add markdown header metadata to docs

This PR refactors the ArxivAPIWrapper class making
`doc_content_chars_max` parameter optional. Additionally, tests have
been added to ensure the functionality of the doc_content_chars_max
parameter.

Fixes #6027 (issue)

+## 🗺️ Guidelines
+
+### 👩‍💻 Contributing Code
 
 To contribute to this project, please follow a ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow.
 Please do not try to push directly to this repo unless you are maintainer.
 
-## 🗺️Contributing Guidelines
+Please follow the checked-in pull request template when opening pull requests. Note related issues and tag relevant
+maintainers.
+
+Pull requests cannot land without passing the formatting, linting and testing checks first. See
+[Common Tasks](#-common-tasks) for how to run these checks locally.
+
+It's essential that we maintain great documentation and testing. If you:
+- Fix a bug
+  - Add a relevant unit or integration test when possible. These live in `tests/unit_tests` and `tests/integration_tests`.
+- Make an improvement
+  - Update any affected example notebooks and documentation. These lives in `docs`.
+  - Update unit and integration tests when relevant.
+- Add a feature
+  - Add a demo notebook in `docs/modules`.
+  - Add unit and integration tests.
+
+We're a small, building-oriented team. If there's something you'd like to add or change, opening a pull request is the
+best way to get our attention.

+### Working with Optional Dependencies
+
+Langchain relies heavily on optional dependencies to keep the Langchain package lightweight.
+
+If you're adding a new dependency to Langchain, assume that it will be an optional dependency, and
+that most users won't have it installed.
+
+Users that do not have the dependency installed should be able to **import** your code without
+any side effects (no warnings, no errors, no exceptions). 
+
+To introduce the dependency to the pyproject.toml file correctly, please do the following: 
+
+1. Add the dependency to the main group as an optional dependency
+  ```bash
+  poetry add --optional [package_name]
+  ```
+2. Open pyproject.toml and add the dependency to the `extended_testing` extra
+3. Relock the poetry file to update the extra.
+  ```bash
+  poetry lock --no-update
+  ```
+4. Add a unit test that the very least attempts to import the new code. Ideally the unit
+test makes use of lightweight fixtures to test the logic of the code.
+5. Please use the `@pytest.mark.requires(package_name)` decorator for any tests that require the dependency.

+===========================
+Deploying LLMs in Production
+===========================
+
+In today's fast-paced technological landscape, the use of Large Language Models (LLMs) is rapidly expanding. As a result, it's crucial for developers to understand how to effectively deploy these models in production environments. LLM interfaces typically fall into two categories:
+
+- **Case 1: Utilizing External LLM Providers (OpenAI, Anthropic, etc.)**
+    In this scenario, most of the computational burden is handled by the LLM providers, while LangChain simplifies the implementation of business logic around these services. This approach includes features such as prompt templating, chat message generation, caching, vector embedding database creation, preprocessing, etc.
+
+- **Case 2: Self-hosted Open-Source Models**
+    Alternatively, developers can opt to use smaller, yet comparably capable, self-hosted open-source LLM models. This approach can significantly decrease costs, latency, and privacy concerns associated with transferring data to external LLM providers.
+
+Regardless of the framework that forms the backbone of your product, deploying LLM applications comes with its own set of challenges. It's vital to understand the trade-offs and key considerations when evaluating serving frameworks.
+
+Outline
+=======
+
+This guide aims to provide a comprehensive overview of the requirements for deploying LLMs in a production setting, focusing on:
+
+- `Designing a Robust LLM Application Service <#robust>`_
+- `Maintaining Cost-Efficiency <#cost>`_
+- `Ensuring Rapid Iteration <#iteration>`_
+
+Understanding these components is crucial when assessing serving systems. LangChain integrates with several open-source projects designed to tackle these issues, providing a robust framework for productionizing your LLM applications. Some notable frameworks include:
+
+- `Ray Serve <../integrations/ray_serve.html>`_
+- `BentoML <https://github.com/ssheng/BentoChain>`_
+- `Modal <../integrations/modal.html>`_
+
+These links will provide further information on each ecosystem, assisting you in finding the best fit for your LLM deployment needs.
+
+Designing a Robust LLM Application Service
+===========================================
+.. _robust:
+
+When deploying an LLM service in production, it's imperative to provide a seamless user experience free from outages. Achieving 24/7 service availability involves creating and maintaining several sub-systems surrounding your application.
+
+Monitoring
+----------
+
+Monitoring forms an integral part of any system running in a production environment. In the context of LLMs, it is essential to monitor both performance and quality metrics.
+
+**Performance Metrics:** These metrics provide insights into the efficiency and capacity of your model. Here are some key examples:
+
+- Query per second (QPS): This measures the number of queries your model processes in a second, offering insights into its utilization.
+- Latency: This metric quantifies the delay from when your client sends a request to when they receive a response.
+- Tokens Per Second (TPS): This represents the number of tokens your model can generate in a second.
+
+**Quality Metrics:** These metrics are typically customized according to the business use-case. For instance, how does the output of your system compare to a baseline, such as a previous version? Although these metrics can be calculated offline, you need to log the necessary data to use them later.
+
+Fault tolerance
+---------------
+
+Your application may encounter errors such as exceptions in your model inference or business logic code, causing failures and disrupting traffic. Other potential issues could arise from the machine running your application, such as unexpected hardware breakdowns or loss of spot-instances during high-demand periods. One way to mitigate these risks is by increasing redundancy through replica scaling and implementing recovery mechanisms for failed replicas. However, model replicas aren't the only potential points of failure. It's essential to build resilience against various failures that could occur at any point in your stack.
+
+
+Zero down time upgrade
+----------------------
+
+System upgrades are often necessary but can result in service disruptions if not handled correctly. One way to prevent downtime during upgrades is by implementing a smooth transition process from the old version to the new one. Ideally, the new version of your LLM service is deployed, and traffic gradually shifts from the old to the new version, maintaining a constant QPS throughout the process.
+
+
+Load balancing
+--------------
+
+Load balancing, in simple terms, is a technique to distribute work evenly across multiple computers, servers, or other resources to optimize the utilization of the system, maximize throughput, minimize response time, and avoid overload of any single resource. Think of it as a traffic officer directing cars (requests) to different roads (servers) so that no single road becomes too congested.
+
+There are several strategies for load balancing. For example, one common method is the *Round Robin* strategy, where each request is sent to the next server in line, cycling back to the first when all servers have received a request. This works well when all servers are equally capable. However, if some servers are more powerful than others, you might use a *Weighted Round Robin* or *Least Connections* strategy, where more requests are sent to the more powerful servers, or to those currently handling the fewest active requests. Let's imagine you're running a LLM chain. If your application becomes popular, you could have hundreds or even thousands of users asking questions at the same time. If one server gets too busy (high load), the load balancer would direct new requests to another server that is less busy. This way, all your users get a timely response and the system remains stable.
+
+
+
+Maintaining Cost-Efficiency and Scalability
+============================================
+.. _cost:
+
+Deploying LLM services can be costly, especially when you're handling a large volume of user interactions. Charges by LLM providers are usually based on tokens used, making a chat system inference on these models potentially expensive. However, several strategies can help manage these costs without compromising the quality of the service.
+
+
+Self-hosting models
+-------------------
+
+Several smaller and open-source LLMs are emerging to tackle the issue of reliance on LLM providers. Self-hosting allows you to maintain similar quality to LLM provider models while managing costs. The challenge lies in building a reliable, high-performing LLM serving system on your own machines. 
+
+Resource Management and Auto-Scaling
+------------------------------------
+
+Computational logic within your application requires precise resource allocation. For instance, if part of your traffic is served by an OpenAI endpoint and another part by a self-hosted model, it's crucial to allocate suitable resources for each. Auto-scaling—adjusting resource allocation based on traffic—can significantly impact the cost of running your application. This strategy requires a balance between cost and responsiveness, ensuring neither resource over-provisioning nor compromised application responsiveness.
+
+Utilizing Spot Instances
+------------------------
+
+On platforms like AWS, spot instances offer substantial cost savings, typically priced at about a third of on-demand instances. The trade-off is a higher crash rate, necessitating a robust fault-tolerance mechanism for effective use.
+
+Independent Scaling
+-------------------
+
+When self-hosting your models, you should consider independent scaling. For example, if you have two translation models, one fine-tuned for French and another for Spanish, incoming requests might necessitate different scaling requirements for each.
+
+Batching requests
+-----------------
+
+In the context of Large Language Models, batching requests can enhance efficiency by better utilizing your GPU resources. GPUs are inherently parallel processors, designed to handle multiple tasks simultaneously. If you send individual requests to the model, the GPU might not be fully utilized as it's only working on a single task at a time. On the other hand, by batching requests together, you're allowing the GPU to work on multiple tasks at once, maximizing its utilization and improving inference speed. This not only leads to cost savings but can also improve the overall latency of your LLM service.
+
+
+In summary, managing costs while scaling your LLM services requires a strategic approach. Utilizing self-hosting models, managing resources effectively, employing auto-scaling, using spot instances, independently scaling models, and batching requests are key strategies to consider. Open-source libraries such as Ray Serve and BentoML are designed to deal with these complexities. 
+
+
+
+Ensuring Rapid Iteration
+========================
+
+.. _iteration:
+
+The LLM landscape is evolving at an unprecedented pace, with new libraries and model architectures being introduced constantly. Consequently, it's crucial to avoid tying yourself to a solution specific to one particular framework. This is especially relevant in serving, where changes to your infrastructure can be time-consuming, expensive, and risky. Strive for infrastructure that is not locked into any specific machine learning library or framework, but instead offers a general-purpose, scalable serving layer. Here are some aspects where flexibility plays a key role:
+
+Model composition
+-----------------
+
+Deploying systems like LangChain demands the ability to piece together different models and connect them via logic. Take the example of building a natural language input SQL query engine. Querying an LLM and obtaining the SQL command is only part of the system. You need to extract metadata from the connected database, construct a prompt for the LLM, run the SQL query on an engine, collect and feed back the response to the LLM as the query runs, and present the results to the user. This demonstrates the need to seamlessly integrate various complex components built in Python into a dynamic chain of logical blocks that can be served together.
+
+Cloud providers
+---------------
+
+Many hosted solutions are restricted to a single cloud provider, which can limit your options in today's multi-cloud world. Depending on where your other infrastructure components are built, you might prefer to stick with your chosen cloud provider.
+
+
+Infrastructure as Code (IaC)
+---------------------------
+
+Rapid iteration also involves the ability to recreate your infrastructure quickly and reliably. This is where Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or Kubernetes YAML files come into play. They allow you to define your infrastructure in code files, which can be version controlled and quickly deployed, enabling faster and more reliable iterations.
+
+
+CI/CD
+-----
+
+In a fast-paced environment, implementing CI/CD pipelines can significantly speed up the iteration process. They help automate the testing and deployment of your LLM applications, reducing the risk of errors and enabling faster feedback and iteration.

+# Baseten
+
+Learn how to use LangChain with models deployed on Baseten.
+
+## Installation and setup
+
+- Create a [Baseten](https://baseten.co) account and [API key](https://docs.baseten.co/settings/api-keys).
+- Install the Baseten Python client with `pip install baseten`
+- Use your API key to authenticate with `baseten login`
+
+## Invoking a model
+
+Baseten integrates with LangChain through the LLM module, which provides a standardized and interoperable interface for models that are deployed on your Baseten workspace.
+
+You can deploy foundation models like WizardLM and Alpaca with one click from the [Baseten model library](https://app.baseten.co/explore/) or if you have your own model, [deploy it with this tutorial](https://docs.baseten.co/deploying-models/deploy).
+
+In this example, we'll work with WizardLM. [Deploy WizardLM here](https://app.baseten.co/explore/wizardlm) and follow along with the deployed [model's version ID](https://docs.baseten.co/managing-models/manage).
+
+```python
+from langchain.llms import Baseten
+
+wizardlm = Baseten(model="MODEL_VERSION_ID", verbose=True)
+
+wizardlm("What is the difference between a Wizard and a Sorcerer?")

+# Concepts
+
+These are concepts and terminology commonly used when developing LLM applications.
+It contains reference to external papers or sources where the concept was first introduced,
+as well as to places in LangChain where the concept is used.
+
+## Chain of Thought
+
+`Chain of Thought (CoT)` is a prompting technique used to encourage the model to generate a series of intermediate reasoning steps.
+A less formal way to induce this behavior is to include “Let’s think step-by-step” in the prompt.
+
+- [Chain-of-Thought Paper](https://arxiv.org/pdf/2201.11903.pdf)
+- [Step-by-Step Paper](https://arxiv.org/abs/2112.00114)
+
+## Action Plan Generation
+
+`Action Plan Generation` is a prompting technique that uses a language model to generate actions to take.
+The results of these actions can then be fed back into the language model to generate a subsequent action.
+
+- [WebGPT Paper](https://arxiv.org/pdf/2112.09332.pdf)
+- [SayCan Paper](https://say-can.github.io/assets/palm_saycan.pdf)
+
+## ReAct
+
+`ReAct` is a prompting technique that combines Chain-of-Thought prompting with action plan generation.
+This induces the model to think about what action to take, then take it.
+
+- [Paper](https://arxiv.org/pdf/2210.03629.pdf)
+- [LangChain Example](../modules/agents/agents/examples/react.ipynb)
+
+## Self-ask
+
+`Self-ask` is a prompting method that builds on top of chain-of-thought prompting.
+In this method, the model explicitly asks itself follow-up questions, which are then answered by an external search engine.
+
+- [Paper](https://ofir.io/self-ask.pdf)
+- [LangChain Example](../modules/agents/agents/examples/self_ask_with_search.ipynb)
+
+## Prompt Chaining
+
+`Prompt Chaining` is combining multiple LLM calls, with the output of one-step being the input to the next.
+
+- [PromptChainer Paper](https://arxiv.org/pdf/2203.06566.pdf)
+- [Language Model Cascades](https://arxiv.org/abs/2207.10342)
+- [ICE Primer Book](https://primer.ought.org/)
+- [Socratic Models](https://socraticmodels.github.io/)
+
+## Memetic Proxy
+
+`Memetic Proxy` is encouraging the LLM
+to respond in a certain way framing the discussion in a context that the model knows of and that 
+will result in that type of response.
+For example, as a conversation between a student and a teacher.
+
+- [Paper](https://arxiv.org/pdf/2102.07350.pdf)
+
+## Self Consistency
+
+`Self Consistency` is a decoding strategy that samples a diverse set of reasoning paths and then selects the most consistent answer.
+Is most effective when combined with Chain-of-thought prompting.
+
+- [Paper](https://arxiv.org/pdf/2203.11171.pdf)
+
+## Inception
+
+`Inception` is also called `First Person Instruction`.
+It is encouraging the model to think a certain way by including the start of the model’s response in the prompt.
+
+- [Example](https://twitter.com/goodside/status/1583262455207460865?s=20&t=8Hz7XBnK1OF8siQrxxCIGQ)
+
+## MemPrompt
+
+`MemPrompt` maintains a memory of errors and user feedback, and uses them to prevent repetition of mistakes.

 ## Chat Prompt Templates
 Similar to LLMs, you can make use of templating by using a `MessagePromptTemplate`. You can build a `ChatPromptTemplate` from one or more `MessagePromptTemplate`s. You can use `ChatPromptTemplate`'s `format_prompt` -- this returns a `PromptValue`, which you can convert to a string or `Message` object, depending on whether you want to use the formatted value as input to an llm or chat model.

 Modules
 -----------
 
-There are several main modules that LangChain provides support for.
-For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.
-These modules are, in increasing order of complexity:
+| These modules are the core abstractions which we view as the building blocks of any LLM-powered application.
+For each module LangChain provides standard, extendable interfaces. LangChain also provides external integrations and even end-to-end implementations for off-the-shelf use.
 
-- `Models <./modules/models.html>`_: The various model types and model integrations LangChain supports.
+| The docs for each module contain quickstart examples, how-to guides, reference docs, and conceptual guides.
 
-- `Prompts <./modules/prompts.html>`_: This includes prompt management, prompt optimization, and prompt serialization.
+| The modules are (from least to most complex):
 
-- `Memory <./modules/memory.html>`_: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.
+- `Models <./modules/models.html>`_: Supported model types and integrations.
 
-- `Indexes <./modules/indexes.html>`_: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.
+- `Prompts <./modules/prompts.html>`_: Prompt management, optimization, and serialization.
 
-- `Chains <./modules/chains.html>`_: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.
+- `Memory <./modules/memory.html>`_: Memory refers to state that is persisted between calls of a chain/agent.
 
-- `Agents <./modules/agents.html>`_: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.
+- `Indexes <./modules/indexes.html>`_: Language models become much more powerful when combined with application-specific data - this module contains interfaces and integrations for loading, querying and updating external data.
 
+- `Chains <./modules/chains.html>`_: Chains are structured sequences of calls (to an LLM or to a different utility).
+
+- `Agents <./modules/agents.html>`_: An agent is a Chain in which an LLM, given a high-level directive and a set of tools, repeatedly decides an action, executes the action and observes the outcome until the high-level directive is complete.
+
+- `Callbacks <./modules/callbacks/getting_started.html>`_: Callbacks let you log and stream the intermediate steps of any chain, making it easy to observe, debug, and evaluate the internals of an application.

+>[Beam](https://docs.beam.cloud/introduction) makes it easy to run code on GPUs, deploy scalable web APIs, 
+> schedule cron jobs, and run massively parallel workloads — without managing any infrastructure.
+ 
+
+## Installation and Setup
+
+- [Create an account](https://www.beam.cloud/)
+- Install the Beam CLI with `curl https://raw.githubusercontent.com/slai-labs/get-beam/main/get-beam.sh -sSfL | sh`
+- Register API keys with `beam configure`
+- Set environment variables (`BEAM_CLIENT_ID`) and (`BEAM_CLIENT_SECRET`)
+- Install the Beam SDK:
+```bash
+pip install beam-sdk
+```
+
+## LLM
+
+
+```python
+from langchain.llms.beam import Beam
+```
+
+### Example of the Beam app
+
+This is the environment you’ll be developing against once you start the app.
+It's also used to define the maximum response length from the model.
+```python
+llm = Beam(model_name="gpt2",
+           name="langchain-gpt2-test",
+           cpu=8,
+           memory="32Gi",
+           gpu="A10G",
+           python_version="python3.8",
+           python_packages=[
+               "diffusers[torch]>=0.10",

+               "xformers",],
+           max_length="50",
+           verbose=False)
+```
+
+### Deploy the Beam app
+
+Once defined, you can deploy your Beam app by calling your model's `_deploy()` method.
+
+```python
+llm._deploy()
+```
+
+### Call the Beam app
+
+Once a beam model is deployed, it can be called by calling your model's `_call()` method.
+This returns the GPT2 text response to your prompt.
+
+```python
+response = llm._call("Running machine learning on a remote GPU")
+```
+
+An example script which deploys the model and calls it would be:
+
+```python
+from langchain.llms.beam import Beam
+import time
+
+llm = Beam(model_name="gpt2",
+           name="langchain-gpt2-test",

+# ClickHouse
+
+This page covers how to use ClickHouse Vector Search within LangChain.
+
+[ClickHouse](https://clickhouse.com) is a open source real-time OLAP database with full SQL support and a wide range of functions to assist users in writing analytical queries. Some of these functions and data structures perform distance operations between vectors, enabling ClickHouse to be used as a vector database.
+
+Due to the fully parallelized query pipeline, ClickHouse can process vector search operations very quickly, especially when performing exact matching through a linear scan over all rows, delivering processing speed comparable to dedicated vector databases.
+
+High compression levels, tunable through custom compression codecs, enable very large datasets to be stored and queried. ClickHouse is not memory-bound, allowing multi-TB datasets containing embeddings to be queried.
+
+The capabilities for computing the distance between two vectors are just another SQL function and can be effectively combined with more traditional SQL filtering and aggregation capabilities. This allows vectors to be stored and queried alongside metadata, and even rich text, enabling a broad array of use cases and applications.
+
+Finally, experimental ClickHouse capabilities like [Approximate Nearest Neighbour (ANN) indices](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/annindexes) support faster approximate matching of vectors and provide a promising development aimed to further enhance the vector matching capabilities of ClickHouse.
+
+## Installation
+- Install clickhouse server by [binary](https://clickhouse.com/docs/en/install) or [docker image](https://hub.docker.com/r/clickhouse/clickhouse-server/)
+- Install the Python SDK with `pip install clickhouse-connect`
+
+### Configure clickhouse vector index
+
+Customize `ClickhouseSettings` object with parameters
+
+    ```python
+    from langchain.vectorstores import ClickHouse, ClickhouseSettings
+    config = ClickhouseSettings(host="<clickhouse-server-host>", port=8123, ...)
+    index = Clickhouse(embedding_function, config)
+    index.add_documents(...)
+    ```
+  
+## Wrappers
+supported functions:
+- `add_texts`
+- `add_documents`
+- `from_texts`
+- `from_documents`
+- `similarity_search`
+- `asimilarity_search`
+- `similarity_search_by_vector`
+- `asimilarity_search_by_vector`
+- `similarity_search_with_relevance_scores`
+
+### VectorStore
+
+There exists a wrapper around open source Clickhouse database, allowing you to use it as a vectorstore,
+whether for semantic search or similar example retrieval.
+
+To import this vectorstore:
+```python
+from langchain.vectorstores import Clickhouse
+```

+# C Transformers
+
+This page covers how to use the [C Transformers](https://github.com/marella/ctransformers) library within LangChain.
+It is broken into two parts: installation and setup, and then references to specific C Transformers wrappers.
+
+## Installation and Setup
+
+- Install the Python package with `pip install ctransformers`
+- Download a supported [GGML model](https://huggingface.co/TheBloke) (see [Supported Models](https://github.com/marella/ctransformers#supported-models))
+
+## Wrappers
+
+### LLM
+
+There exists a CTransformers LLM wrapper, which you can access with:
+
+```python
+from langchain.llms import CTransformers
+```
+
+It provides a unified interface for all models:
+
+```python
+llm = CTransformers(model='/path/to/ggml-gpt-2.bin', model_type='gpt2')
+
+print(llm('AI is going to'))
+```
+
+If you are getting `illegal instruction` error, try using `lib='avx'` or `lib='basic'`:
+
+```py
+llm = CTransformers(model='/path/to/ggml-gpt-2.bin', model_type='gpt2', lib='avx')
+```
+
+It can be used with models hosted on the Hugging Face Hub:
+
+```py
+llm = CTransformers(model='marella/gpt-2-ggml')
+```
+
+If a model repo has multiple model files (`.bin` files), specify a model file using:
+
+```py
+llm = CTransformers(model='marella/gpt-2-ggml', model_file='ggml-model.bin')
+```
+
+Additional parameters can be passed using the `config` parameter:
+
+```py
+config = {'max_new_tokens': 256, 'repetition_penalty': 1.1}
+
+llm = CTransformers(model='marella/gpt-2-ggml', config=config)
+```
+
+See [Documentation](https://github.com/marella/ctransformers#config) for a list of available parameters.
+
+For a more detailed walkthrough of this, see [this notebook](../modules/models/llms/integrations/ctransformers.ipynb).

+Databricks
+==========
+
+The [Databricks](https://www.databricks.com/) Lakehouse Platform unifies data, analytics, and AI on one platform.
+
+Databricks embraces the LangChain ecosystem in various ways:
+
+1. Databricks connector for the SQLDatabase Chain: SQLDatabase.from_databricks() provides an easy way to query your data on Databricks through LangChain
+2. Databricks-managed MLflow integrates with LangChain: Tracking and serving LangChain applications with fewer steps
+3. Databricks as an LLM provider: Deploy your fine-tuned LLMs on Databricks via serving endpoints or cluster driver proxy apps, and query it as langchain.llms.Databricks
+4. Databricks Dolly: Databricks open-sourced Dolly which allows for commercial use, and can be accessed through the Hugging Face Hub
+
+Databricks connector for the SQLDatabase Chain
+----------------------------------------------
+You can connect to [Databricks runtimes](https://docs.databricks.com/runtime/index.html) and [Databricks SQL](https://www.databricks.com/product/databricks-sql) using the SQLDatabase wrapper of LangChain. See the notebook [Connect to Databricks](./databricks/databricks.html) for details.
+
+Databricks-managed MLflow integrates with LangChain
+---------------------------------------------------
+
+MLflow is an open source platform to manage the ML lifecycle, including experimentation, reproducibility, deployment, and a central model registry. See the notebook [MLflow Callback Handler](./mlflow_tracking.ipynb) for details about MLflow's integration with LangChain.
+
+Databricks provides a fully managed and hosted version of MLflow integrated with enterprise security features, high availability, and other Databricks workspace features such as experiment and run management and notebook revision capture. MLflow on Databricks offers an integrated experience for tracking and securing machine learning model training runs and running machine learning projects. See [MLflow guide](https://docs.databricks.com/mlflow/index.html) for more details.
+
+Databricks-managed MLflow makes it more convenient to develop LangChain applications on Databricks. For MLflow tracking, you don't need to set the tracking uri. For MLflow Model Serving, you can save LangChain Chains in the MLflow langchain flavor, and then register and serve the Chain with a few clicks on Databricks, with credentials securely managed by MLflow Model Serving.
+
+Databricks as an LLM provider
+-----------------------------
+
+The notebook [Wrap Databricks endpoints as LLMs](../modules/models/llms/integrations/databricks.html) illustrates the method to wrap Databricks endpoints as LLMs in LangChain. It supports two types of endpoints: the serving endpoint, which is recommended for both production and development, and the cluster driver proxy app, which is recommended for interactive development. 
+
+Databricks endpoints support Dolly, but are also great for hosting models like MPT-7B or any other models from the Hugging Face ecosystem. Databricks endpoints can also be used with proprietary models like OpenAI to provide a governance layer for enterprises.
+
+Databricks Dolly
+----------------
+
+Databricks’ Dolly is an instruction-following large language model trained on the Databricks machine learning platform that is licensed for commercial use. The model is available on Hugging Face Hub as databricks/dolly-v2-12b. See the notebook [Hugging Face Hub](../modules/models/llms/integrations/huggingface_hub.html) for instructions to access it through the Hugging Face Hub integration with LangChain.
