 ## 🚀 How does LangChain help?
-
 The main value props of the LangChain libraries are:
-
 1. **Components**: composable building blocks, tools and integrations for working with language models. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not
 2. **Off-the-shelf chains**: built-in assemblages of components for accomplishing higher-level tasks
 
-Off-the-shelf chains make it easy to get started. Components make it easy to customize existing chains and build new ones.
+Off-the-shelf chains make it easy to get started. Components make it easy to customize existing chains and build new ones. 
 
 ## LangChain Expression Language (LCEL)
 
-LCEL is a key part of LangChain, allowing you to build and organize chains of processes in a straightforward, declarative manner. It was designed to support taking prototypes directly into production without needing to alter any code. This means you can use LCEL to set up everything from basic "prompt + LLM" setups to intricate, multi-step workflows.
+LCEL is the foundation of many of LangChain's components, and is a declarative way to compose chains. LCEL was designed from day 1 to support putting prototypes in production, with no code changes, from the simplest “prompt + LLM” chain to the most complex chains.

-**Abstract:** Retrieval-Augmented Large Language Models (LLMs), which incorporate the
-non-parametric knowledge from external knowledge bases into LLMs, have emerged
-as a promising approach to enhancing response accuracy in several tasks, such
-as Question-Answering (QA). However, even though there are various approaches
-dealing with queries of different complexities, they either handle simple
-queries with unnecessary computational overhead or fail to adequately address
-complex multi-step queries; yet, not all user requests fall into only one of
-the simple or complex categories. In this work, we propose a novel adaptive QA
-framework, that can dynamically select the most suitable strategy for
-(retrieval-augmented) LLMs from the simplest to the most sophisticated ones
-based on the query complexity. Also, this selection process is operationalized
-with a classifier, which is a smaller LM trained to predict the complexity
-level of incoming queries with automatically collected labels, obtained from
-actual predicted outcomes of models and inherent inductive biases in datasets.
-This approach offers a balanced strategy, seamlessly adapting between the
-iterative and single-step retrieval-augmented LLMs, as well as the no-retrieval
-methods, in response to a range of query complexities. We validate our model on
-a set of open-domain QA datasets, covering multiple query complexities, and
-show that ours enhances the overall efficiency and accuracy of QA systems,
-compared to relevant baselines including the adaptive retrieval approaches.

-**Abstract:** Code generation problems differ from common natural language problems - they
-require matching the exact syntax of the target language, identifying happy
-paths and edge cases, paying attention to numerous small details in the problem
-spec, and addressing other code-specific issues and requirements. Hence, many
-of the optimizations and tricks that have been successful in natural language
-generation may not be effective for code tasks. In this work, we propose a new
-approach to code generation by LLMs, which we call AlphaCodium - a test-based,
-multi-stage, code-oriented iterative flow, that improves the performances of
-LLMs on code problems. We tested AlphaCodium on a challenging code generation
-dataset called CodeContests, which includes competitive programming problems
-from platforms such as Codeforces. The proposed flow consistently and
-significantly improves results. On the validation set, for example, GPT-4
-accuracy (pass@5) increased from 19% with a single well-designed direct prompt
-to 44% with the AlphaCodium flow. Many of the principles and best practices
-acquired in this work, we believe, are broadly applicable to general code
-generation tasks. Full implementation is available at:

-is the sequential decoding approach adopted by almost all state-of-the-art

-decoding to complete the contents of each skeleton point in parallel. Not only
-does SoT provide considerable speed-ups across 12 LLMs, but it can also
-potentially improve the answer quality on several question categories. SoT is
-an initial attempt at data-centric optimization for inference efficiency, and

-**Abstract:** While recent language models have the ability to take long contexts as input,
-relatively little is known about how well they use longer context. We analyze
-the performance of language models on two tasks that require identifying
-relevant information in their input contexts: multi-document question answering
-and key-value retrieval. We find that performance can degrade significantly
-when changing the position of relevant information, indicating that current
-language models do not robustly make use of information in long input contexts.
-In particular, we observe that performance is often highest when relevant
-information occurs at the beginning or end of the input context, and
-significantly degrades when models must access relevant information in the
-middle of long contexts, even for explicitly long-context models. Our analysis
-provides a better understanding of how language models use their input context
-and provides new evaluation protocols for future long-context language models.

-**Abstract:** As AI systems become more capable, we would like to enlist their help to
-supervise other AIs. We experiment with methods for training a harmless AI
-assistant through self-improvement, without any human labels identifying
-harmful outputs. The only human oversight is provided through a list of rules
-or principles, and so we refer to the method as 'Constitutional AI'. The
-process involves both a supervised learning and a reinforcement learning phase.
-In the supervised phase we sample from an initial model, then generate
-self-critiques and revisions, and then finetune the original model on revised
-responses. In the RL phase, we sample from the finetuned model, use a model to
-evaluate which of the two samples is better, and then train a preference model
-from this dataset of AI preferences. We then train with RL using the preference
-model as the reward signal, i.e. we use 'RL from AI Feedback' (RLAIF). As a
-result we are able to train a harmless but non-evasive AI assistant that
-engages with harmful queries by explaining its objections to them. Both the SL
-and RL methods can leverage chain-of-thought style reasoning to improve the
-human-judged performance and transparency of AI decision making. These methods
-make it possible to control AI behavior more precisely and with far fewer human
-labels.

-**Abstract:** Neural information retrieval (IR) has greatly advanced search and other
-knowledge-intensive language tasks. While many neural IR methods encode queries
-and documents into single-vector representations, late interaction models
-produce multi-vector representations at the granularity of each token and
-decompose relevance modeling into scalable token-level computations. This
-decomposition has been shown to make late interaction more effective, but it
-inflates the space footprint of these models by an order of magnitude. In this
-work, we introduce ColBERTv2, a retriever that couples an aggressive residual
-compression mechanism with a denoised supervision strategy to simultaneously
-improve the quality and space footprint of late interaction. We evaluate
-ColBERTv2 across a wide range of benchmarks, establishing state-of-the-art
-quality within and outside the training domain while reducing the space
-footprint of late interaction models by 6--10$\times$.

 ### Runnable interface
 <span data-heading-keywords="invoke,runnable"></span>
 
-To make it as easy as possible to create custom chains, we've implemented a ["Runnable"](https://python.langchain.com/v0.2/api_reference/core/runnables/langchain_core.runnables.base.Runnable.html#langchain_core.runnables.base.Runnable) protocol. Many LangChain components implement the `Runnable` protocol, including chat models, LLMs, output parsers, retrievers, prompt templates, and more. There are also several useful primitives for working with runnables, which you can read about below.

 One common prompting technique for achieving better performance is to include examples as part of the prompt.

-### Few-shot prompting
-
-One of the most effective ways to improve model performance is to give a model examples of what you want it to do. The technique of adding example inputs and expected outputs to a model prompt is known as "few-shot prompting". There are a few things to think about when doing few-shot prompting:
-
-1. How are examples generated?
-2. How many examples are in each prompt?
-3. How are examples selected at runtime?
-4. How are examples formatted in the prompt?
-
-Here are the considerations for each.
-
-#### 1. Generating examples
-
-The first and most important step of few-shot prompting is coming up with a good dataset of examples. Good examples should be relevant at runtime, clear, informative, and provide information that was not already known to the model.
-
-At a high-level, the basic ways to generate examples are:
-- Manual: a person/people generates examples they think are useful.
-- Better model: a better (presumably more expensive/slower) model's responses are used as examples for a worse (presumably cheaper/faster) model.
-- User feedback: users (or labelers) leave feedback on interactions with the application and examples are generated based on that feedback (for example, all interactions with positive feedback could be turned into examples).
-- LLM feedback: same as user feedback but the process is automated by having models evaluate themselves.
-
-Which approach is best depends on your task. For tasks where a small number core principles need to be understood really well, it can be valuable hand-craft a few really good examples.
-For tasks where the space of correct behaviors is broader and more nuanced, it can be useful to generate many examples in a more automated fashion so that there's a higher likelihood of there being some highly relevant examples for any runtime input.
-
-**Single-turn v.s. multi-turn examples**
-
-Another dimension to think about when generating examples is what the example is actually showing.
-
-The simplest types of examples just have a user input and an expected model output. These are single-turn examples.
-
-One more complex type if example is where the example is an entire conversation, usually in which a model initially responds incorrectly and a user then tells the model how to correct its answer.
-This is called a multi-turn example. Multi-turn examples can be useful for more nuanced tasks where its useful to show common errors and spell out exactly why they're wrong and what should be done instead.
-
-#### 2. Number of examples
-
-Once we have a dataset of examples, we need to think about how many examples should be in each prompt.
-The key tradeoff is that more examples generally improve performance, but larger prompts increase costs and latency.
-And beyond some threshold having too many examples can start to confuse the model.
-Finding the right number of examples is highly dependent on the model, the task, the quality of the examples, and your cost and latency constraints.
-Anecdotally, the better the model is the fewer examples it needs to perform well and the more quickly you hit steeply diminishing returns on adding more examples.
-But, the best/only way to reliably answer this question is to run some experiments with different numbers of examples.
-
-#### 3. Selecting examples
-
-Assuming we are not adding our entire example dataset into each prompt, we need to have a way of selecting examples from our dataset based on a given input. We can do this:
-- Randomly
-- By (semantic or keyword-based) similarity of the inputs
-- Based on some other constraints, like token size
-
-LangChain has a number of [`ExampleSelectors`](/docs/concepts/#example-selectors) which make it easy to use any of these techniques.
-
-Generally, selecting by semantic similarity leads to the best model performance. But how important this is is again model and task specific, and is something worth experimenting with.
-
-#### 4. Formatting examples
-
-Most state-of-the-art models these days are chat models, so we'll focus on formatting examples for those. Our basic options are to insert the examples:
-- In the system prompt as a string
-- As their own messages
-
-If we insert our examples into the system prompt as a string, we'll need to make sure it's clear to the model where each example begins and which parts are the input versus output. Different models respond better to different syntaxes, like [ChatML](https://learn.microsoft.com/en-us/azure/ai-services/openai/how-to/chat-markup-language), XML, TypeScript, etc.
-
-If we insert our examples as messages, where each example is represented as a sequence of Human, AI messages, we might want to also assign [names](/docs/concepts/#messages) to our messages like `"example_user"` and `"example_assistant"` to make it clear that these messages correspond to different actors than the latest input message.
-
-**Formatting tool call examples**
-
-One area where formatting examples as messages can be tricky is when our example outputs have tool calls. This is because different models have different constraints on what types of message sequences are allowed when any tool calls are generated.
-- Some models require that any AIMessage with tool calls be immediately followed by ToolMessages for every tool call,
-- Some models additionally require that any ToolMessages be immediately followed by an AIMessage before the next HumanMessage,
-- Some models require that tools are passed in to the model if there are any tool calls / ToolMessages in the chat history.
-
-These requirements are model-specific and should be checked for the model you are using. If your model requires ToolMessages after tool calls and/or AIMessages after ToolMessages and your examples only include expected tool calls and not the actual tool outputs, you can try adding dummy ToolMessages / AIMessages to the end of each example with generic contents to satisfy the API constraints.
-In these cases it's especially worth experimenting with inserting your examples as strings versus messages, as having dummy messages can adversely affect certain models.
-
-You can see a case study of how Anthropic and OpenAI respond to different few-shot prompting techniques on two different tool calling benchmarks [here](https://blog.langchain.dev/few-shot-prompting-to-improve-tool-calling-performance/).

 ### Retrieval
 
 LLMs are trained on a large but fixed dataset, limiting their ability to reason over private or recent information. Fine-tuning an LLM with specific facts is one way to mitigate this, but is often [poorly suited for factual recall](https://www.anyscale.com/blog/fine-tuning-is-for-form-not-facts) and [can be costly](https://www.glean.com/blog/how-to-build-an-ai-assistant-for-the-enterprise).
