For these applications, LangChain simplifies the entire application lifecycle:
- **Open-source libraries**: Build your applications using LangChain's open-source [building blocks](https://python.langchain.com/v0.2/docs/concepts#langchain-expression-language-lcel), [components](https://python.langchain.com/v0.2/docs/concepts), and [third-party integrations](https://python.langchain.com/v0.2/docs/integrations/platforms/).
Use [LangGraph](/docs/concepts/#langgraph) to build stateful agents with first-class streaming and human-in-the-loop support.
- **Productionization**: Inspect, monitor, and evaluate your apps with [LangSmith](https://docs.smith.langchain.com/) so that you can constantly optimize and deploy with confidence.
- **Deployment**: Turn your LangGraph applications into production-ready APIs and Assistants with [LangGraph Cloud](https://langchain-ai.github.io/langgraph/cloud/).
- **Open-source libraries**: Build your applications using LangChain's [modular building blocks](https://python.langchain.com/docs/expression_language/) and [components](https://python.langchain.com/docs/modules/). Integrate with hundreds of [third-party providers](https://python.langchain.com/docs/integrations/platforms/).
- **Productionization**: Inspect, monitor, and evaluate your apps with [LangSmith](https://python.langchain.com/docs/langsmith/) so that you can constantly optimize and deploy with confidence.
- **Deployment**: Turn any chain into a REST API with [LangServe](https://python.langchain.com/docs/langserve).
### Open-source libraries
- **`langchain-core`**: Base abstractions and LangChain Expression Language.
- **`langchain-community`**: Third party integrations.
- Some integrations have been further split into **partner packages** that only rely on **`langchain-core`**. Examples include **`langchain_openai`** and **`langchain_anthropic`**.
- **`langchain`**: Chains, agents, and retrieval strategies that make up an application's cognitive architecture.
- **[`LangGraph`](https://langchain-ai.github.io/langgraph/)**: A library for building robust and stateful multi-actor applications with LLMs by modeling steps as edges and nodes in a graph. Integrates smoothly with LangChain, but can be used without it.
- **[`LangGraph`](https://python.langchain.com/docs/langgraph)**: A library for building robust and stateful multi-actor applications with LLMs by modeling steps as edges and nodes in a graph.
### Productionization:
- **[LangSmith](https://docs.smith.langchain.com/)**: A developer platform that lets you debug, test, evaluate, and monitor chains built on any LLM framework and seamlessly integrates with LangChain.
- **[LangSmith](https://python.langchain.com/docs/langsmith)**: A developer platform that lets you debug, test, evaluate, and monitor chains built on any LLM framework and seamlessly integrates with LangChain.
### Deployment:

**📚 Retrieval**
**📚 Retrieval:**
Retrieval Augmented Generation involves [loading data](https://python.langchain.com/v0.2/docs/concepts/#document-loaders) from a variety of sources, [preparing it](https://python.langchain.com/v0.2/docs/concepts/#text-splitters), then [searching over (a.k.a. retrieving from)](https://python.langchain.com/v0.2/docs/concepts/#retrievers) it for use in the generation step.

**🤖 Agents**
**🤖 Agents:**
Agents allow an LLM autonomy over how a task is accomplished. Agents make decisions about which Actions to take, then take that Action, observe the result, and repeat until the task is complete. LangChain provides a [standard interface for agents](https://python.langchain.com/v0.2/docs/concepts/#agents), along with [LangGraph](https://github.com/langchain-ai/langgraph) for building custom agents.

"The historical and cultural context of the image is tied to the Great Depression and the Dust Bowl, both of which affected the Cherokee people in Oklahoma. The photograph was taken during this period, and its subject, Florence Owens Thompson, was a leader within her community who worked tirelessly to help those affected by these crises.\n",

"2. Historical and cultural context of the image: The photo was taken in 1936 during the Great Depression, when many families struggled to make ends meet. Dorothea Lange, a renowned American photographer, took this iconic photograph that became an emblem of poverty and hardship experienced by many Americans at that time.\n",
"3. Interpretation of the image's symbolism and meaning: The image conveys a sense of unity and resilience despite adversity. The woman and her children are standing together, displaying their strength as a family unit in the face of economic challenges. The photograph also serves as a reminder of the importance of empathy and support for those who are struggling.\n",

## Self-Discover: Large Language Models Self-Compose Reasoning Structures
- **arXiv id:** 2402.03620v1
- **Title:** Self-Discover: Large Language Models Self-Compose Reasoning Structures
- **Authors:** Pei Zhou, Jay Pujara, Xiang Ren, et al.
- **Published Date:** 2024-02-06
- **URL:** http://arxiv.org/abs/2402.03620v1
- **LangChain:**
- **Cookbook:** [self-discover](https://github.com/langchain-ai/langchain/blob/master/cookbook/self-discover.ipynb)
**Abstract:** We introduce SELF-DISCOVER, a general framework for LLMs to self-discover the
task-intrinsic reasoning structures to tackle complex reasoning problems that
are challenging for typical prompting methods. Core to the framework is a
self-discovery process where LLMs select multiple atomic reasoning modules such
as critical thinking and step-by-step thinking, and compose them into an
explicit reasoning structure for LLMs to follow during decoding. SELF-DISCOVER
substantially improves GPT-4 and PaLM 2's performance on challenging reasoning
benchmarks such as BigBench-Hard, grounded agent reasoning, and MATH, by as
much as 32% compared to Chain of Thought (CoT). Furthermore, SELF-DISCOVER
outperforms inference-intensive methods such as CoT-Self-Consistency by more
than 20%, while requiring 10-40x fewer inference compute. Finally, we show that
the self-discovered reasoning structures are universally applicable across
model families: from PaLM 2-L to GPT-4, and from GPT-4 to Llama2, and share
commonalities with human reasoning patterns.
## RAPTOR: Recursive Abstractive Processing for Tree-Organized Retrieval
- **arXiv id:** 2401.18059v1
- **Title:** RAPTOR: Recursive Abstractive Processing for Tree-Organized Retrieval
- **Authors:** Parth Sarthi, Salman Abdullah, Aditi Tuli, et al.
- **Published Date:** 2024-01-31
- **URL:** http://arxiv.org/abs/2401.18059v1
- **LangChain:**
- **Cookbook:** [RAPTOR](https://github.com/langchain-ai/langchain/blob/master/cookbook/RAPTOR.ipynb)
**Abstract:** Retrieval-augmented language models can better adapt to changes in world
state and incorporate long-tail knowledge. However, most existing methods
retrieve only short contiguous chunks from a retrieval corpus, limiting
holistic understanding of the overall document context. We introduce the novel
approach of recursively embedding, clustering, and summarizing chunks of text,
constructing a tree with differing levels of summarization from the bottom up.
At inference time, our RAPTOR model retrieves from this tree, integrating
information across lengthy documents at different levels of abstraction.
Controlled experiments show that retrieval with recursive summaries offers
significant improvements over traditional retrieval-augmented LMs on several
tasks. On question-answering tasks that involve complex, multi-step reasoning,
we show state-of-the-art results; for example, by coupling RAPTOR retrieval
with the use of GPT-4, we can improve the best performance on the QuALITY
benchmark by 20% in absolute accuracy.
## Corrective Retrieval Augmented Generation

**Abstract:** Large language models (LLMs) inevitably exhibit hallucinations since the
accuracy of generated texts cannot be secured solely by the parametric
knowledge they encapsulate. Although retrieval-augmented generation (RAG) is a
practicable complement to LLMs, it relies heavily on the relevance of retrieved
documents, raising concerns about how the model behaves if retrieval goes
wrong. To this end, we propose the Corrective Retrieval Augmented Generation
(CRAG) to improve the robustness of generation. Specifically, a lightweight
retrieval evaluator is designed to assess the overall quality of retrieved
documents for a query, returning a confidence degree based on which different
knowledge retrieval actions can be triggered. Since retrieval from static and
limited corpora can only return sub-optimal documents, large-scale web searches
are utilized as an extension for augmenting the retrieval results. Besides, a
decompose-then-recompose algorithm is designed for retrieved documents to
selectively focus on key information and filter out irrelevant information in
them. CRAG is plug-and-play and can be seamlessly coupled with various
RAG-based approaches. Experiments on four datasets covering short- and
long-form generation tasks show that CRAG can significantly improve the
performance of RAG-based approaches.

**Abstract:** We introduce Mixtral 8x7B, a Sparse Mixture of Experts (SMoE) language model.
Mixtral has the same architecture as Mistral 7B, with the difference that each
layer is composed of 8 feedforward blocks (i.e. experts). For every token, at
each layer, a router network selects two experts to process the current state
and combine their outputs. Even though each token only sees two experts, the
selected experts can be different at each timestep. As a result, each token has
access to 47B parameters, but only uses 13B active parameters during inference.
Mixtral was trained with a context size of 32k tokens and it outperforms or
matches Llama 2 70B and GPT-3.5 across all evaluated benchmarks. In particular,
Mixtral vastly outperforms Llama 2 70B on mathematics, code generation, and
multilingual benchmarks. We also provide a model fine-tuned to follow
instructions, Mixtral 8x7B - Instruct, that surpasses GPT-3.5 Turbo,
Claude-2.1, Gemini Pro, and Llama 2 70B - chat model on human benchmarks. Both
the base and instruct models are released under the Apache 2.0 license.

**Abstract:** Dense retrieval has become a prominent method to obtain relevant context or
world knowledge in open-domain NLP tasks. When we use a learned dense retriever
on a retrieval corpus at inference time, an often-overlooked design choice is
the retrieval unit in which the corpus is indexed, e.g. document, passage, or
sentence. We discover that the retrieval unit choice significantly impacts the
performance of both retrieval and downstream tasks. Distinct from the typical
approach of using passages or sentences, we introduce a novel retrieval unit,
proposition, for dense retrieval. Propositions are defined as atomic
expressions within text, each encapsulating a distinct factoid and presented in
a concise, self-contained natural language format. We conduct an empirical
comparison of different retrieval granularity. Our results reveal that
proposition-based retrieval significantly outperforms traditional passage or
sentence-based methods in dense retrieval. Moreover, retrieval by proposition
also enhances the performance of downstream QA tasks, since the retrieved texts
are more condensed with question-relevant information, reducing the need for
lengthy input tokens and minimizing the inclusion of extraneous, irrelevant
information.

**Abstract:** Retrieval-augmented language models (RALMs) represent a substantial
advancement in the capabilities of large language models, notably in reducing
factual hallucination by leveraging external knowledge sources. However, the
reliability of the retrieved information is not always guaranteed. The
retrieval of irrelevant data can lead to misguided responses, and potentially
causing the model to overlook its inherent knowledge, even when it possesses
adequate information to address the query. Moreover, standard RALMs often
struggle to assess whether they possess adequate knowledge, both intrinsic and
retrieved, to provide an accurate answer. In situations where knowledge is
lacking, these systems should ideally respond with "unknown" when the answer is
unattainable. In response to these challenges, we introduces Chain-of-Noting
(CoN), a novel approach aimed at improving the robustness of RALMs in facing
noisy, irrelevant documents and in handling unknown scenarios. The core idea of
CoN is to generate sequential reading notes for retrieved documents, enabling a
thorough evaluation of their relevance to the given question and integrating
this information to formulate the final answer. We employed ChatGPT to create
training data for CoN, which was subsequently trained on an LLaMa-2 7B model.
Our experiments across four open-domain QA benchmarks show that RALMs equipped
with CoN significantly outperform standard RALMs. Notably, CoN achieves an
average improvement of +7.9 in EM score given entirely noisy retrieved
documents and +10.5 in rejection rates for real-time questions that fall
outside the pre-training knowledge scope.

**Abstract:** Despite their remarkable capabilities, large language models (LLMs) often
produce responses containing factual inaccuracies due to their sole reliance on
the parametric knowledge they encapsulate. Retrieval-Augmented Generation
(RAG), an ad hoc approach that augments LMs with retrieval of relevant
knowledge, decreases such issues. However, indiscriminately retrieving and
incorporating a fixed number of retrieved passages, regardless of whether
retrieval is necessary, or passages are relevant, diminishes LM versatility or
can lead to unhelpful response generation. We introduce a new framework called
Self-Reflective Retrieval-Augmented Generation (Self-RAG) that enhances an LM's
quality and factuality through retrieval and self-reflection. Our framework
trains a single arbitrary LM that adaptively retrieves passages on-demand, and
generates and reflects on retrieved passages and its own generations using
special tokens, called reflection tokens. Generating reflection tokens makes
the LM controllable during the inference phase, enabling it to tailor its
behavior to diverse task requirements. Experiments show that Self-RAG (7B and
13B parameters) significantly outperforms state-of-the-art LLMs and
retrieval-augmented models on a diverse set of tasks. Specifically, Self-RAG
outperforms ChatGPT and retrieval-augmented Llama2-chat on Open-domain QA,
reasoning and fact verification tasks, and it shows significant gains in
improving factuality and citation accuracy for long-form generations relative
to these models.

LLMs to do abstractions to derive high-level concepts and first principles from
instances containing specific details. Using the concepts and principles to
guide reasoning, LLMs significantly improve their abilities in following a
correct reasoning path towards the solution. We conduct experiments of
Step-Back Prompting with PaLM-2L, GPT-4 and Llama2-70B models, and observe
substantial performance gains on various challenging reasoning-intensive tasks
including STEM, Knowledge QA, and Multi-Hop Reasoning. For instance, Step-Back
Prompting improves PaLM-2L performance on MMLU (Physics and Chemistry) by 7%
and 11% respectively, TimeQA by 27%, and MuSiQue by 7%.

Llama 2-Chat in order to enable the community to build on our work and
contribute to the responsible development of LLMs.

**Abstract:** Large Language Models (LLMs) play powerful, black-box readers in the
retrieve-then-read pipeline, making remarkable progress in knowledge-intensive
tasks. This work introduces a new framework, Rewrite-Retrieve-Read instead of
the previous retrieve-then-read for the retrieval-augmented LLMs from the
perspective of the query rewriting. Unlike prior studies focusing on adapting
either the retriever or the reader, our approach pays attention to the
adaptation of the search query itself, for there is inevitably a gap between
the input text and the needed knowledge in retrieval. We first prompt an LLM to
generate the query, then use a web search engine to retrieve contexts.
Furthermore, to better align the query to the frozen modules, we propose a
trainable scheme for our pipeline. A small language model is adopted as a
trainable rewriter to cater to the black-box LLM reader. The rewriter is
trained using the feedback of the LLM reader by reinforcement learning.
Evaluation is conducted on downstream tasks, open-domain QA and multiple-choice
QA. Experiments results show consistent performance improvement, indicating
that our framework is proven effective and scalable, and brings a new framework
for retrieval-augmented LLM.

**Abstract:** In this paper, we introduce the Tree-of-Thought (ToT) framework, a novel
approach aimed at improving the problem-solving capabilities of auto-regressive
large language models (LLMs). The ToT technique is inspired by the human mind's
approach for solving complex reasoning tasks through trial and error. In this
process, the human mind explores the solution space through a tree-like thought
process, allowing for backtracking when necessary. To implement ToT as a
software system, we augment an LLM with additional modules including a prompter
agent, a checker module, a memory module, and a ToT controller. In order to
solve a given problem, these modules engage in a multi-round conversation with
the LLM. The memory module records the conversation and state history of the
problem solving process, which allows the system to backtrack to the previous
steps of the thought-process and explore other directions from there. To verify
the effectiveness of the proposed technique, we implemented a ToT-based solver
for the Sudoku Puzzle. Experimental results show that the ToT framework can
significantly increase the success rate of Sudoku puzzle solving. Our
implementation of the ToT-based Sudoku solver is available on GitHub:

**Abstract:** Large language models (LLMs) have recently been shown to deliver impressive
performance in various NLP tasks. To tackle multi-step reasoning tasks,
few-shot chain-of-thought (CoT) prompting includes a few manually crafted
step-by-step reasoning demonstrations which enable LLMs to explicitly generate
reasoning steps and improve their reasoning task accuracy. To eliminate the
manual effort, Zero-shot-CoT concatenates the target problem statement with
"Let's think step by step" as an input prompt to LLMs. Despite the success of
Zero-shot-CoT, it still suffers from three pitfalls: calculation errors,
missing-step errors, and semantic misunderstanding errors. To address the
missing-step errors, we propose Plan-and-Solve (PS) Prompting. It consists of
two components: first, devising a plan to divide the entire task into smaller
subtasks, and then carrying out the subtasks according to the plan. To address
the calculation errors and improve the quality of generated reasoning steps, we
extend PS prompting with more detailed instructions and derive PS+ prompting.
We evaluate our proposed prompting strategy on ten datasets across three
reasoning problems. The experimental results over GPT-3 show that our proposed
zero-shot prompting consistently outperforms Zero-shot-CoT across all datasets
by a large margin, is comparable to or exceeds Zero-shot-Program-of-Thought
Prompting, and has comparable performance with 8-shot CoT prompting on the math
reasoning problem. The code can be found at

**Abstract:** Instruction tuning large language models (LLMs) using machine-generated
instruction-following data has improved zero-shot capabilities on new tasks,
but the idea is less explored in the multimodal field. In this paper, we
present the first attempt to use language-only GPT-4 to generate multimodal
language-image instruction-following data. By instruction tuning on such
generated data, we introduce LLaVA: Large Language and Vision Assistant, an
end-to-end trained large multimodal model that connects a vision encoder and
LLM for general-purpose visual and language understanding.Our early experiments
show that LLaVA demonstrates impressive multimodel chat abilities, sometimes
exhibiting the behaviors of multimodal GPT-4 on unseen images/instructions, and
yields a 85.1% relative score compared with GPT-4 on a synthetic multimodal
instruction-following dataset. When fine-tuned on Science QA, the synergy of
LLaVA and GPT-4 achieves a new state-of-the-art accuracy of 92.53%. We make
GPT-4 generated visual instruction tuning data, our model and code base
publicly available.

**Abstract:** Believable proxies of human behavior can empower interactive applications
ranging from immersive environments to rehearsal spaces for interpersonal
communication to prototyping tools. In this paper, we introduce generative
agents--computational software agents that simulate believable human behavior.
Generative agents wake up, cook breakfast, and head to work; artists paint,
while authors write; they form opinions, notice each other, and initiate
conversations; they remember and reflect on days past as they plan the next
day. To enable generative agents, we describe an architecture that extends a
large language model to store a complete record of the agent's experiences
using natural language, synthesize those memories over time into higher-level
reflections, and retrieve them dynamically to plan behavior. We instantiate
generative agents to populate an interactive sandbox environment inspired by
The Sims, where end users can interact with a small town of twenty five agents
using natural language. In an evaluation, these generative agents produce
believable individual and emergent social behaviors: for example, starting with
only a single user-specified notion that one agent wants to throw a Valentine's
Day party, the agents autonomously spread invitations to the party over the
next two days, make new acquaintances, ask each other out on dates to the
party, and coordinate to show up for the party together at the right time. We
demonstrate through ablation that the components of our agent
architecture--observation, planning, and reflection--each contribute critically
to the believability of agent behavior. By fusing large language models with
computational, interactive agents, this work introduces architectural and
interaction patterns for enabling believable simulations of human behavior.

**Abstract:** The rapid advancement of chat-based language models has led to remarkable

human input to guide the conversation, which can be challenging and
time-consuming. This paper explores the potential of building scalable
techniques to facilitate autonomous cooperation among communicative agents, and
provides insight into their "cognitive" processes. To address the challenges of
achieving autonomous cooperation, we propose a novel communicative agent
framework named role-playing. Our approach involves using inception prompting
to guide chat agents toward task completion while maintaining consistency with
human intentions. We showcase how role-playing can be used to generate
conversational data for studying the behaviors and capabilities of a society of
agents, providing a valuable resource for investigating conversational language
models. In particular, we conduct comprehensive studies on
instruction-following cooperation in multi-agent settings. Our contributions
include introducing a novel communicative agent framework, offering a scalable
approach for studying the cooperative behaviors and capabilities of multi-agent
systems, and open-sourcing our library to support research on communicative
agents and beyond: https://github.com/camel-ai/camel.

**Abstract:** Solving complicated AI tasks with different domains and modalities is a key
step toward artificial general intelligence. While there are numerous AI models
available for various domains and modalities, they cannot handle complicated AI
tasks autonomously. Considering large language models (LLMs) have exhibited
exceptional abilities in language understanding, generation, interaction, and
reasoning, we advocate that LLMs could act as a controller to manage existing
AI models to solve complicated AI tasks, with language serving as a generic
interface to empower this. Based on this philosophy, we present HuggingGPT, an
LLM-powered agent that leverages LLMs (e.g., ChatGPT) to connect various AI
models in machine learning communities (e.g., Hugging Face) to solve AI tasks.
Specifically, we use ChatGPT to conduct task planning when receiving a user
request, select models according to their function descriptions available in
Hugging Face, execute each subtask with the selected AI model, and summarize
the response according to the execution results. By leveraging the strong
language capability of ChatGPT and abundant AI models in Hugging Face,
HuggingGPT can tackle a wide range of sophisticated AI tasks spanning different
modalities and domains and achieve impressive results in language, vision,
speech, and other challenging tasks, which paves a new way towards the
realization of artificial general intelligence.

**Abstract:** We report the development of GPT-4, a large-scale, multimodal model which can
accept image and text inputs and produce text outputs. While less capable than
humans in many real-world scenarios, GPT-4 exhibits human-level performance on
various professional and academic benchmarks, including passing a simulated bar
exam with a score around the top 10% of test takers. GPT-4 is a
Transformer-based model pre-trained to predict the next token in a document.
The post-training alignment process results in improved performance on measures
of factuality and adherence to desired behavior. A core component of this
project was developing infrastructure and optimization methods that behave
predictably across a wide range of scales. This allowed us to accurately
predict some aspects of GPT-4's performance based on models trained with no
more than 1/1,000th the compute of GPT-4.

**Abstract:** Potential harms of large language models can be mitigated by watermarking
model output, i.e., embedding signals into generated text that are invisible to
humans but algorithmically detectable from a short span of tokens. We propose a
watermarking framework for proprietary language models. The watermark can be
embedded with negligible impact on text quality, and can be detected using an
efficient open-source algorithm without access to the language model API or
parameters. The watermark works by selecting a randomized set of "green" tokens
before a word is generated, and then softly promoting use of green tokens
during sampling. We propose a statistical test for detecting the watermark with
interpretable p-values, and derive an information-theoretic framework for
analyzing the sensitivity of the watermark. We test the watermark using a
multi-billion parameter model from the Open Pretrained Transformer (OPT)
family, and discuss robustness and security.

**Abstract:** While dense retrieval has been shown effective and efficient across tasks and
languages, it remains difficult to create effective fully zero-shot dense
retrieval systems when no relevance label is available. In this paper, we
recognize the difficulty of zero-shot learning and encoding relevance. Instead,
we propose to pivot through Hypothetical Document Embeddings~(HyDE). Given a
query, HyDE first zero-shot instructs an instruction-following language model
(e.g. InstructGPT) to generate a hypothetical document. The document captures
relevance patterns but is unreal and may contain false details. Then, an
unsupervised contrastively learned encoder~(e.g. Contriever) encodes the
document into an embedding vector. This vector identifies a neighborhood in the
corpus embedding space, where similar real documents are retrieved based on
vector similarity. This second step ground the generated document to the actual
corpus, with the encoder's dense bottleneck filtering out the incorrect
details. Our experiments show that HyDE significantly outperforms the
state-of-the-art unsupervised dense retriever Contriever and shows strong
performance comparable to fine-tuned retrievers, across various tasks (e.g. web
search, QA, fact verification) and languages~(e.g. sw, ko, ja).

**Abstract:** The spread of misinformation, propaganda, and flawed argumentation has been
amplified in the Internet era. Given the volume of data and the subtlety of
identifying violations of argumentation norms, supporting information analytics
tasks, like content moderation, with trustworthy methods that can identify
logical fallacies is essential. In this paper, we formalize prior theoretical
work on logical fallacies into a comprehensive three-stage evaluation framework
of detection, coarse-grained, and fine-grained classification. We adapt
existing evaluation datasets for each stage of the evaluation. We employ three
families of robust and explainable methods based on prototype reasoning,
instance-based reasoning, and knowledge injection. The methods combine language
models with background knowledge and explainable mechanisms. Moreover, we
address data sparsity with strategies for data augmentation and curriculum
learning. Our three-stage framework natively consolidates prior datasets and
methods from existing tasks, like propaganda detection, serving as an
overarching evaluation testbed. We extensively evaluate these methods on our
datasets, focusing on their robustness and explainability. Our results provide
insight into the strengths and weaknesses of the methods on different
components and fallacy classes, indicating that fallacy identification is a
challenging task that may require specialized forms of reasoning to capture
various classes. We share our open-source code and data on GitHub to support
further work on logical fallacy identification.

**Abstract:** Large language models (LLMs) have exhibited remarkable capabilities in
learning from explanations in prompts, but there has been limited understanding
of exactly how these explanations function or why they are effective. This work
aims to better understand the mechanisms by which explanations are used for
in-context learning. We first study the impact of two different factors on the
performance of prompts with explanations: the computation trace (the way the
solution is decomposed) and the natural language used to express the prompt. By
perturbing explanations on three controlled tasks, we show that both factors
contribute to the effectiveness of explanations. We further study how to form
maximally effective sets of explanations for solving a given test query. We
find that LLMs can benefit from the complementarity of the explanation set:
diverse reasoning skills shown by different exemplars can lead to better
performance. Therefore, we propose a maximal marginal relevance-based exemplar
selection approach for constructing exemplar sets that are both relevant as
well as complementary, which successfully improves the in-context learning
performance across three real-world tasks on multiple LLMs.

**Abstract:** Large language models (LLMs) have recently demonstrated an impressive ability
to perform arithmetic and symbolic reasoning tasks, when provided with a few
examples at test time ("few-shot prompting"). Much of this success can be
attributed to prompting methods such as "chain-of-thought'', which employ LLMs
for both understanding the problem description by decomposing it into steps, as
well as solving each step of the problem. While LLMs seem to be adept at this
sort of step-by-step decomposition, LLMs often make logical and arithmetic
mistakes in the solution part, even when the problem is decomposed correctly.
In this paper, we present Program-Aided Language models (PAL): a novel approach
that uses the LLM to read natural language problems and generate programs as
the intermediate reasoning steps, but offloads the solution step to a runtime
such as a Python interpreter. With PAL, decomposing the natural language
problem into runnable steps remains the only learning task for the LLM, while
solving is delegated to the interpreter. We demonstrate this synergy between a
neural LLM and a symbolic interpreter across 13 mathematical, symbolic, and
algorithmic reasoning tasks from BIG-Bench Hard and other benchmarks. In all
these natural language reasoning tasks, generating code using an LLM and
reasoning using a Python interpreter leads to more accurate results than much
larger models. For example, PAL using Codex achieves state-of-the-art few-shot
accuracy on the GSM8K benchmark of math word problems, surpassing PaLM-540B
which uses chain-of-thought by absolute 15% top-1. Our code and data are
publicly available at http://reasonwithpal.com/ .

**Abstract:** While large language models (LLMs) have demonstrated impressive capabilities
across tasks in language understanding and interactive decision making, their
abilities for reasoning (e.g. chain-of-thought prompting) and acting (e.g.
action plan generation) have primarily been studied as separate topics. In this
paper, we explore the use of LLMs to generate both reasoning traces and
task-specific actions in an interleaved manner, allowing for greater synergy
between the two: reasoning traces help the model induce, track, and update
action plans as well as handle exceptions, while actions allow it to interface
with external sources, such as knowledge bases or environments, to gather
additional information. We apply our approach, named ReAct, to a diverse set of
language and decision making tasks and demonstrate its effectiveness over
state-of-the-art baselines, as well as improved human interpretability and
trustworthiness over methods without reasoning or acting components.
Concretely, on question answering (HotpotQA) and fact verification (Fever),
ReAct overcomes issues of hallucination and error propagation prevalent in
chain-of-thought reasoning by interacting with a simple Wikipedia API, and
generates human-like task-solving trajectories that are more interpretable than
baselines without reasoning traces. On two interactive decision making
benchmarks (ALFWorld and WebShop), ReAct outperforms imitation and
reinforcement learning methods by an absolute success rate of 34% and 10%
respectively, while being prompted with only one or two in-context examples.

**Abstract:** Traditional data lakes provide critical data infrastructure for analytical
workloads by enabling time travel, running SQL queries, ingesting data with
ACID transactions, and visualizing petabyte-scale datasets on cloud storage.
They allow organizations to break down data silos, unlock data-driven
decision-making, improve operational efficiency, and reduce costs. However, as
deep learning usage increases, traditional data lakes are not well-designed for
applications such as natural language processing (NLP), audio processing,
computer vision, and applications involving non-tabular datasets. This paper
presents Deep Lake, an open-source lakehouse for deep learning applications
developed at Activeloop. Deep Lake maintains the benefits of a vanilla data
lake with one key difference: it stores complex data, such as images, videos,
annotations, as well as tabular data, in the form of tensors and rapidly
streams the data over the network to (a) Tensor Query Language, (b) in-browser
visualization engine, or (c) deep learning frameworks without sacrificing GPU
utilization. Datasets stored in Deep Lake can be accessed from PyTorch,
TensorFlow, JAX, and integrate with numerous MLOps tools.

**Abstract:** Scaling multilingual representation learning beyond the hundred most frequent
languages is challenging, in particular to cover the long tail of low-resource
languages. A promising approach has been to train one-for-all multilingual
models capable of cross-lingual transfer, but these models often suffer from
insufficient capacity and interference between unrelated languages. Instead, we
move away from this approach and focus on training multiple language (family)
specific representations, but most prominently enable all languages to still be
encoded in the same representational space. To achieve this, we focus on
teacher-student training, allowing all encoders to be mutually compatible for
bitext mining, and enabling fast learning of new languages. We introduce a new
teacher-student training scheme which combines supervised and self-supervised
training, allowing encoders to take advantage of monolingual training data,
which is valuable in the low-resource setting.
Our approach significantly outperforms the original LASER encoder. We study
very low-resource languages and handle 50 African languages, many of which are
not covered by any other model. For these languages, we train sentence
encoders, mine bitexts, and validate the bitexts by training NMT systems.

language model. We find that, without any finetuning, Codex is a strong
baseline on the Spider benchmark; we also analyze the failure modes of Codex in
this setting. Furthermore, we demonstrate on the GeoQuery and Scholar
benchmarks that a small number of in-domain examples provided in the prompt
enables Codex to perform better than state-of-the-art models finetuned on such
few-shot examples.

**Abstract:** Today's probabilistic language generators fall short when it comes to
producing coherent and fluent text despite the fact that the underlying models
perform well under standard metrics, e.g., perplexity. This discrepancy has
puzzled the language generation community for the last few years. In this work,
we posit that the abstraction of natural language generation as a discrete
stochastic process--which allows for an information-theoretic analysis--can
provide new insights into the behavior of probabilistic language generators,
e.g., why high-probability texts can be dull or repetitive. Humans use language
as a means of communicating information, aiming to do so in a simultaneously
efficient and error-minimizing manner; in fact, psycholinguistics research
suggests humans choose each word in a string with this subconscious goal in
mind. We formally define the set of strings that meet this criterion: those for
which each word has an information content close to the expected information
content, i.e., the conditional entropy of our model. We then propose a simple
and efficient procedure for enforcing this criterion when generating from
probabilistic models, which we call locally typical sampling. Automatic and
human evaluations show that, in comparison to nucleus and top-k sampling,
locally typical sampling offers competitive performance (in both abstractive
summarization and story generation) in terms of quality while consistently
reducing degenerate repetitions.
## Learning Transferable Visual Models From Natural Language Supervision

**Abstract:** State-of-the-art computer vision systems are trained to predict a fixed set
of predetermined object categories. This restricted form of supervision limits
their generality and usability since additional labeled data is needed to
specify any other visual concept. Learning directly from raw text about images
is a promising alternative which leverages a much broader source of
supervision. We demonstrate that the simple pre-training task of predicting
which caption goes with which image is an efficient and scalable way to learn
SOTA image representations from scratch on a dataset of 400 million (image,
text) pairs collected from the internet. After pre-training, natural language
is used to reference learned visual concepts (or describe new ones) enabling
zero-shot transfer of the model to downstream tasks. We study the performance
of this approach by benchmarking on over 30 different existing computer vision
datasets, spanning tasks such as OCR, action recognition in videos,
geo-localization, and many types of fine-grained object classification. The
model transfers non-trivially to most tasks and is often competitive with a
fully supervised baseline without the need for any dataset specific training.
For instance, we match the accuracy of the original ResNet-50 on ImageNet
zero-shot without needing to use any of the 1.28 million training examples it
was trained on. We release our code and pre-trained model weights at
https://github.com/OpenAI/CLIP.

**Abstract:** Large-scale language models show promising text generation capabilities, but
users cannot easily control particular aspects of the generated text. We
release CTRL, a 1.63 billion-parameter conditional transformer language model,
trained to condition on control codes that govern style, content, and
task-specific behavior. Control codes were derived from structure that
naturally co-occurs with raw text, preserving the advantages of unsupervised
learning while providing more explicit control over text generation. These
codes also allow CTRL to predict which parts of the training data are most
likely given a sequence. This provides a potential method for analyzing large
amounts of data via model-based source attribution. We have released multiple
full-sized, pretrained versions of CTRL at https://github.com/salesforce/ctrl.

**Abstract:** BERT (Devlin et al., 2018) and RoBERTa (Liu et al., 2019) has set a new
state-of-the-art performance on sentence-pair regression tasks like semantic
textual similarity (STS). However, it requires that both sentences are fed into
the network, which causes a massive computational overhead: Finding the most
similar pair in a collection of 10,000 sentences requires about 50 million
inference computations (~65 hours) with BERT. The construction of BERT makes it
unsuitable for semantic similarity search as well as for unsupervised tasks
like clustering.
In this publication, we present Sentence-BERT (SBERT), a modification of the
pretrained BERT network that use siamese and triplet network structures to
derive semantically meaningful sentence embeddings that can be compared using
cosine-similarity. This reduces the effort for finding the most similar pair
from 65 hours with BERT / RoBERTa to about 5 seconds with SBERT, while
maintaining the accuracy from BERT.
We evaluate SBERT and SRoBERTa on common STS tasks and transfer learning
tasks, where it outperforms other state-of-the-art sentence embeddings methods.

# General guidelines
Here are some things to keep in mind for all types of contributions:
- Follow the ["fork and pull request"](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project) workflow.
- Fill out the checked-in pull request template when opening pull requests. Note related issues and tag relevant maintainers.
- Ensure your PR passes formatting, linting, and testing checks before requesting a review.
- If you would like comments or feedback on your current progress, please open an issue or discussion and tag a maintainer.
- See the sections on [Testing](/docs/contributing/code/setup#testing) and [Formatting and Linting](/docs/contributing/code/setup#formatting-and-linting) for how to run these checks locally.
- Backwards compatibility is key. Your changes must not be breaking, except in case of critical bug and security fixes.
- Look for duplicate PRs or issues that have already been opened before opening a new one.
- Keep scope as isolated as possible. As a general rule, your changes should not affect more than one package at a time.
## Bugfixes
We encourage and appreciate bugfixes. We ask that you:
- Explain the bug in enough detail for maintainers to be able to reproduce it.
- If an accompanying issue exists, link to it. Prefix with `Fixes` so that the issue will close automatically when the PR is merged.
- Avoid breaking changes if possible.
- Include unit tests that fail without the bugfix.
If you come across a bug and don't know how to fix it, we ask that you open an issue for it describing in detail the environment in which you encountered the bug.
## New features
We aim to keep the bar high for new features. We generally don't accept new core abstractions, changes to infra, changes to dependencies,
or new agents/chains from outside contributors without an existing GitHub discussion or issue that demonstrates an acute need for them.
- New features must come with docs, unit tests, and (if appropriate) integration tests.
- New integrations must come with docs, unit tests, and (if appropriate) integration tests.
- See [this page](/docs/contributing/integrations) for more details on contributing new integrations.
- New functionality should not inherit from or use deprecated methods or classes.
- We will reject features that are likely to lead to security vulnerabilities or reports.
- Do not add any hard dependencies. Integrations may add optional dependencies.

# Documentation Style Guide
# LangChain Documentation Style Guide
## Introduction
As LangChain continues to grow, the surface area of documentation required to cover it continues to grow too.
This page provides guidelines for anyone writing documentation for LangChain, as well as some of our philosophies around
@@ -10,139 +12,116 @@ organization and structure.
## Philosophy
LangChain's documentation follows the [Diataxis framework](https://diataxis.fr).
Under this framework, all documentation falls under one of four categories: [Tutorials](/docs/contributing/documentation/style_guide/#tutorials),
[How-to guides](/docs/contributing/documentation/style_guide/#how-to-guides),
[References](/docs/contributing/documentation/style_guide/#references), and [Explanations](/docs/contributing/documentation/style_guide/#conceptual-guide).
LangChain's documentation aspires to follow the [Diataxis framework](https://diataxis.fr).
Under this framework, all documentation falls under one of four categories:
### Tutorials
Tutorials are lessons that take the reader through a practical activity. Their purpose is to help the user
gain understanding of concepts and how they interact by showing one way to achieve some goal in a hands-on way. They should **avoid** giving
multiple permutations of ways to achieve that goal in-depth. Instead, it should guide a new user through a recommended path to accomplishing the tutorial's goal. While the end result of a tutorial does not necessarily need to
be completely production-ready, it should be useful and practically satisfy the the goal that you clearly stated in the tutorial's introduction. Information on how to address additional scenarios
belongs in how-to guides.
To quote the Diataxis website:
> A tutorial serves the users *acquisition* of skills and knowledge - their study. Its purpose is not to help the user get something done, but to help them learn.
In LangChain, these are often higher level guides that show off end-to-end use cases.
Some examples include:
- [Build a Simple LLM Application with LCEL](/docs/tutorials/llm_chain/)
- [Build a Retrieval Augmented Generation (RAG) App](/docs/tutorials/rag/)
A good structural rule of thumb is to follow the structure of this [example from Numpy](https://numpy.org/numpy-tutorials/content/tutorial-svd.html).
Here are some high-level tips on writing a good tutorial:
- Focus on guiding the user to get something done, but keep in mind the end-goal is more to impart principles than to create a perfect production system.
- Be specific, not abstract and follow one path.
- No need to go deeply into alternative approaches, but its ok to reference them, ideally with a link to an appropriate how-to guide.
- Get "a point on the board" as soon as possible - something the user can run that outputs something.
- You can iterate and expand afterwards.
- Try to frequently checkpoint at given steps where the user can run code and see progress.
- Focus on results, not technical explanation.
- Crosslink heavily to appropriate conceptual/reference pages.
- The first time you mention a LangChain concept, use its full name (e.g. "LangChain Expression Language (LCEL)"), and link to its conceptual/other documentation page.
- It's also helpful to add a prerequisite callout that links to any pages with necessary background information.
- End with a recap/next steps section summarizing what the tutorial covered and future reading, such as related how-to guides.
### How-to guides
A how-to guide, as the name implies, demonstrates how to do something discrete and specific.
It should assume that the user is already familiar with underlying concepts, and is trying to solve an immediate problem, but
should still give some background or list the scenarios where the information contained within can be relevant.
They can and should discuss alternatives if one approach may be better than another in certain cases.
To quote the Diataxis website:
> A how-to guide serves the work of the already-competent user, whom you can assume to know what they want to do, and to be able to follow your instructions correctly.
Some examples include:
- [How to: return structured data from a model](/docs/how_to/structured_output/)
- [How to: write a custom chat model](/docs/how_to/custom_chat_model/)
Here are some high-level tips on writing a good how-to guide:
- Clearly explain what you are guiding the user through at the start.
- Assume higher intent than a tutorial and show what the user needs to do to get that task done.
- Assume familiarity of concepts, but explain why suggested actions are helpful.
- Crosslink heavily to conceptual/reference pages.
- Discuss alternatives and responses to real-world tradeoffs that may arise when solving a problem.
- Use lots of example code.
- Prefer full code blocks that the reader can copy and run.
- End with a recap/next steps section summarizing what the tutorial covered and future reading, such as other related how-to guides.
### Conceptual guide
LangChain's conceptual guide falls under the **Explanation** quadrant of Diataxis. They should cover LangChain terms and concepts
in a more abstract way than how-to guides or tutorials, and should be geared towards curious users interested in
gaining a deeper understanding of the framework. Try to avoid excessively large code examples - the goal here is to
impart perspective to the user rather than to finish a practical project. These guides should cover **why** things work they way they do.
This guide on documentation style is meant to fall under this category.
To quote the Diataxis website:
> The perspective of explanation is higher and wider than that of the other types. It does not take the users eye-level view, as in a how-to guide, or a close-up view of the machinery, like reference material. Its scope in each case is a topic - “an area of knowledge”, that somehow has to be bounded in a reasonable, meaningful way.
Some examples include:
- [Retrieval conceptual docs](/docs/concepts/#retrieval)
- [Chat model conceptual docs](/docs/concepts/#chat-models)
Here are some high-level tips on writing a good conceptual guide:
- Explain design decisions. Why does concept X exist and why was it designed this way?
- Use analogies and reference other concepts and alternatives
- Avoid blending in too much reference content
- You can and should reference content covered in other guides, but make sure to link to them
### References
References contain detailed, low-level information that describes exactly what functionality exists and how to use it.
In LangChain, this is mainly our API reference pages, which are populated from docstrings within code.
References pages are generally not read end-to-end, but are consulted as necessary when a user needs to know
how to use something specific.
To quote the Diataxis website:
> The only purpose of a reference guide is to describe, as succinctly as possible, and in an orderly way. Whereas the content of tutorials and how-to guides are led by needs of the user, reference material is led by the product it describes.
Many of the reference pages in LangChain are automatically generated from code,
but here are some high-level tips on writing a good docstring:
- Be concise
- Discuss special cases and deviations from a user's expectations
- Go into detail on required inputs and outputs
- Light details on when one might use the feature are fine, but in-depth details belong in other sections.
- **Tutorials**: Lessons that take the reader by the hand through a series of conceptual steps to complete a project.
- An example of this is our [LCEL streaming guide](/docs/how_to/streaming).
- Our guides on [custom components](/docs/how_to/custom_chat_model) is another one.
- **How-to guides**: Guides that take the reader through the steps required to solve a real-world problem.
- The clearest examples of this are our [Use case](/docs/how_to#use-cases) quickstart pages.
- **Reference**: Technical descriptions of the machinery and how to operate it.
- Our [Runnable interface](/docs/concepts#interface) page is an example of this.
- The [API reference pages](https://api.python.langchain.com/) are another.
- **Explanation**: Explanations that clarify and illuminate a particular topic.
- The [LCEL primitives pages](/docs/how_to/sequence) are an example of this.
Each category serves a distinct purpose and requires a specific approach to writing and structuring the content.
## General guidelines
## Taxonomy
Keeping the above in mind, we have sorted LangChain's docs into categories. It is helpful to think in these terms
when contributing new documentation:
### Getting started
The [getting started section](/docs/introduction) includes a high-level introduction to LangChain, a quickstart that
tours LangChain's various features, and logistical instructions around installation and project setup.
It contains elements of **How-to guides** and **Explanations**.
### Use cases
[Use cases](/docs/how_to#use-cases) are guides that are meant to show how to use LangChain to accomplish a specific task (RAG, information extraction, etc.).
The quickstarts should be good entrypoints for first-time LangChain developers who prefer to learn by getting something practical prototyped,
then taking the pieces apart retrospectively. These should mirror what LangChain is good at.
The quickstart pages here should fit the **How-to guide** category, with the other pages intended to be **Explanations** of more
in-depth concepts and strategies that accompany the main happy paths.
:::note
The below sections are listed roughly in order of increasing level of abstraction.
:::
### Expression Language
[LangChain Expression Language (LCEL)](/docs/concepts#langchain-expression-language) is the fundamental way that most LangChain components fit together, and this section is designed to teach
developers how to use it to build with LangChain's primitives effectively.
This section should contains **Tutorials** that teach how to stream and use LCEL primitives for more abstract tasks, **Explanations** of specific behaviors,
and some **References** for how to use different methods in the Runnable interface.
### Components
The [components section](/docs/concepts) covers concepts one level of abstraction higher than LCEL.
Abstract base classes like `BaseChatModel` and `BaseRetriever` should be covered here, as well as core implementations of these base classes,
such as `ChatPromptTemplate` and `RecursiveCharacterTextSplitter`. Customization guides belong here too.
This section should contain mostly conceptual **Tutorials**, **References**, and **Explanations** of the components they cover.
:::note
As a general rule of thumb, everything covered in the `Expression Language` and `Components` sections (with the exception of the `Composition` section of components) should
cover only components that exist in `langchain_core`.
:::
### Integrations
The [integrations](/docs/integrations/platforms/) are specific implementations of components. These often involve third-party APIs and services.
If this is the case, as a general rule, these are maintained by the third-party partner.
This section should contain mostly **Explanations** and **References**, though the actual content here is more flexible than other sections and more at the
discretion of the third-party provider.
:::note
Concepts covered in `Integrations` should generally exist in `langchain_community` or specific partner packages.
:::
### Guides and Ecosystem
The [Guides](/docs/tutorials) and [Ecosystem](/docs/langsmith/) sections should contain guides that address higher-level problems than the sections above.
This includes, but is not limited to, considerations around productionization and development workflows.
These should contain mostly **How-to guides**, **Explanations**, and **Tutorials**.
### API references
LangChain's API references. Should act as **References** (as the name implies) with some **Explanation**-focused content as well.
## Sample developer journey
We have set up our docs to assist a new developer to LangChain. Let's walk through the intended path:
- The developer lands on https://python.langchain.com, and reads through the introduction and the diagram.
- If they are just curious, they may be drawn to the [Quickstart](/docs/tutorials/llm_chain) to get a high-level tour of what LangChain contains.
- If they have a specific task in mind that they want to accomplish, they will be drawn to the Use-Case section. The use-case should provide a good, concrete hook that shows the value LangChain can provide them and be a good entrypoint to the framework.
- They can then move to learn more about the fundamentals of LangChain through the Expression Language sections.
- Next, they can learn about LangChain's various components and integrations.
- Finally, they can get additional knowledge through the Guides.
This is only an ideal of course - sections will inevitably reference lower or higher-level concepts that are documented in other sections.
## Guidelines
Here are some other guidelines you should think about when writing and organizing documentation.
We generally do not merge new tutorials from outside contributors without an actue need.
We welcome updates as well as new integration docs, how-tos, and references.
### Avoid duplication
Multiple pages that cover the same material in depth are difficult to maintain and cause confusion. There should
be only one (very rarely two), canonical pages for a given concept or feature. Instead, you should link to other guides.
### Link to other sections
### Linking to other sections
Because sections of the docs do not exist in a vacuum, it is important to link to other sections as often as possible
to allow a developer to learn more about an unfamiliar topic inline.
This includes linking to the API references as well as conceptual sections!
### Be concise
### Conciseness
In general, take a less-is-more approach. If a section with a good explanation of a concept already exists, you should link to it rather than
re-explain it, unless the concept you are documenting presents some new wrinkle.
@@ -151,10 +130,9 @@ Be concise, including in code samples.
### General style
- Use active voice and present tense whenever possible
- Use examples and code snippets to illustrate concepts and usage
- Use appropriate header levels (`#`, `##`, `###`, etc.) to organize the content hierarchically

LangChain is organized as a [monorepo](https://en.wikipedia.org/wiki/Monorepo) that contains multiple packages.
You can check out our [installation guide](/docs/how_to/installation/) for more on how they fit together.

For each query, it retrieves a set of relevant documents and takes the unique union across all queries to get a larger set of potentially relevant documents.
