# Weaviate
This page covers how to use the Weaviate ecosystem within LangChain.
What is Weaviate?
**Weaviate in a nutshell:**
- Weaviate is an open-source database of the type vector search engine.
- Weaviate allows you to store JSON documents in a class property-like fashion while attaching machine learning vectors to these documents to represent them in vector space.
- Weaviate can be used stand-alone (aka bring your vectors) or with a variety of modules that can do the vectorization for you and extend the core capabilities.
- Weaviate has a GraphQL-API to access your data easily.
- We aim to bring your vector search set up to production to query in mere milliseconds (check our [open source benchmarks](https://weaviate.io/developers/weaviate/current/benchmarks/) to see if Weaviate fits your use case).
- Get to know Weaviate in the [basics getting started guide](https://weaviate.io/developers/weaviate/current/core-knowledge/basics.html) in under five minutes.
**Weaviate in detail:**
Weaviate is a low-latency vector search engine with out-of-the-box support for different media types (text, images, etc.). It offers Semantic Search, Question-Answer Extraction, Classification, Customizable Models (PyTorch/TensorFlow/Keras), etc. Built from scratch in Go, Weaviate stores both objects and vectors, allowing for combining vector search with structured filtering and the fault tolerance of a cloud-native database. It is all accessible through GraphQL, REST, and various client-side programming languages.
## Installation and Setup
- Install the Python SDK with `pip install weaviate-client`
## Wrappers
### VectorStore
There exists a wrapper around Weaviate indexes, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores import Weaviate
```
For a more detailed walkthrough of the Weaviate wrapper, see [this notebook](../modules/utils/combine_docs_examples/vectorstores.ipynb)

Agents
======
The first category of how-to guides here cover specific parts of working with agents.
`Custom Tools <agents/custom_tools.ipynb>`_: How to create custom tools that an agent can use.
`Intermediate Steps <agents/intermediate_steps.ipynb>`_: How to access and use intermediate steps to get more visibility into the internals of an agent.
`Custom Agent <agents/custom_agent.ipynb>`_: How to create a custom agent (specifically, a custom LLM + prompt to drive that agent).
`Multi Input Tools <agents/multi_input_tool.ipynb>`_: How to use a tool that requires multiple inputs with an agent.
The next set of examples are all end-to-end agents for specific applications.
In all examples there is an Agent with a particular set of tools.
- Tools: A tool can be anything that takes in a string and returns a string. This means that you can use both the primitives AND the chains found in `this <chains.rst>`_ documentation. LangChain also provides a list of easily loadable tools. For detailed information on those, please see `this documentation <../explanation/tools.md>`_
- Agents: An agent uses an LLMChain to determine which tools to use. For a list of all available agent types, see `here <../explanation/agents.md>`_.
**MRKL**
- **Tools used**: Search, SQLDatabaseChain, LLMMathChain
- **Agent used**: `zero-shot-react-description`
- `Paper <https://arxiv.org/pdf/2205.00445.pdf>`_
- **Note**: This is the most general purpose example, so if you are looking to use an agent with arbitrary tools, please start here.
- `Example Notebook <agents/mrkl.ipynb>`_
**Self-Ask-With-Search**
- **Tools used**: Search
- **Agent used**: `self-ask-with-search`
- `Paper <https://ofir.io/self-ask.pdf>`_
- `Example Notebook <agents/self_ask_with_search.ipynb>`_
**ReAct**
- **Tools used**: Wikipedia Docstore
- **Agent used**: `react-docstore`

Chains
======
The examples here are all end-to-end chains for specific applications.
A chain is made up of links, which can be either primitives or other chains.
The following primitives exist as options to use for links:
#. `LLM: <../reference/modules/llms.rst>`_ A language model takes text as input and outputs text.
#. `PromptTemplate: <../reference/modules/prompt.rst>`_ A prompt template takes arbitrary string inputs and returns a final formatted string.
#. `Python REPL: <../reference/modules/python.rst>`_ A Python REPL takes a string representing a Python command to run, runs that command, and then returns anything that was printed during that run.
#. `SQL Database: <../reference/modules/sql_database.rst>`_ A SQL database takes a string representing a SQL command as input and executes that command against the database. If any rows are returned, then those are cast to a string and returned.
#. `Search: <../reference/modules/serpapi.rst>`_ A search object takes a string as input and executes that against a search object, returning any results.
With these primitives in mind, the following chains exist:
**LLMChain**
- **Links Used**: PromptTemplate, LLM
- **Notes**: This chain is the simplest chain, and is widely used by almost every other chain. This chain takes arbitrary user input, creates a prompt with it from the PromptTemplate, passes that to the LLM, and then returns the output of the LLM as the final output.
- `Example Notebook <chains/llm_chain.ipynb>`_
**LLMMath**
- **Links Used**: Python REPL, LLMChain
- **Notes**: This chain takes user input (a math question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.
- `Example Notebook <chains/llm_math.ipynb>`_
**PAL**
- **Links Used**: Python REPL, LLMChain
- **Notes**: This chain takes user input (a reasoning question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.
- `Paper <https://arxiv.org/abs/2211.10435>`_
- `Example Notebook <chains/pal.ipynb>`_
**SQLDatabase Chain**
- **Links Used**: SQLDatabase, LLMChain
- **Notes**: This chain takes user input (a question), uses a first LLM chain to construct a SQL query to run against the SQL database, and then uses another LLMChain to take the results of that query and use it to answer the original question.

# Core Concepts
This section goes over the core concepts of LangChain.
Understanding these will go a long way in helping you understand the codebase and how to construct chains.
## PromptTemplates
PromptTemplates generically have a `format` method that takes in variables and returns a formatted string.
The most simple implementation of this is to have a template string with some variables in it, and then format it with the incoming variables.
More complex iterations dynamically construct the template string from few shot examples, etc.
For a more detailed explanation of how LangChain approaches prompts and prompt templates, see [here](/examples/prompts/prompt_management).
## LLMs
Wrappers around Large Language Models (in particular, the `generate` ability of large language models) are at the core of LangChain functionality.
These wrappers are classes that are callable: they take in an input string, and return the generated output string.
## Embeddings
These classes are very similar to the LLM classes in that they are wrappers around models,
but rather than return a string they return an embedding (list of floats). These are particularly useful when
implementing semantic search functionality. They expose separate methods for embedding queries versus embedding documents.
## Vectorstores
These are datastores that store documents. They expose a method for passing in a string and finding similar documents.
## Chains
These are pipelines that combine multiple of the above ideas.
They vary greatly in complexity and are combination of generic, highly configurable pipelines and more narrow (but usually more complex) pipelines.
## Agents
As opposed to a chain, whether the steps to be taken are known ahead of time, agents
use an LLM to determine which tools to call and in what order.
## Memory
By default, Chains and Agents are stateless, meaning that they treat each incoming query independently.
In some applications (chatbots being a GREAT example) it is highly important to remember previous interactions,
both at a short term but also at a long term level. The concept of "Memory" exists to do exactly that.

# Setting up your environment
Using LangChain will usually require integrations with one or more model providers, data stores, apis, etc.
There are two components to setting this up, installing the correct python packages and setting the right environment variables.
## Python packages
The python package needed varies based on the integration. See the list of integrations for details.
There should also be helpful error messages raised if you try to run an integration and are missing any required python packages.
## Environment Variables
The environment variable needed varies based on the integration. See the list of integrations for details.
There should also be helpful error messages raised if you try to run an integration and are missing any required environment variables.
You can set the environment variable in a few ways.
If you are trying to set the environment variable `FOO` to value `bar`, here are the ways you could do so:
- From the command line:
```
export FOO=bar
```
- From the python notebook/script:
```python
import os
os.environ["FOO"] = "bar"
```
For the Getting Started example, we will be using OpenAI's APIs, so we will first need to install their SDK:
```
pip install openai
```
We will then need to set the environment variable. Let's do this from inside the Jupyter notebook (or Python script).
```python
import os
os.environ["OPENAI_API_KEY"] = "..."
```

# Quickstart Guide
This tutorial gives you a quick walkthrough about building an end-to-end language model application with LangChain.
## Installation
To get started, install LangChain with the following command:
```bash
pip install langchain
```
## Environment Setup
Using LangChain will usually require integrations with one or more model providers, data stores, apis, etc.
For this example, we will be using OpenAI's APIs, so we will first need to install their SDK:
```bash
pip install openai
```
We will then need to set the environment variable in the terminal.
```bash
export OPENAI_API_KEY="..."
```
Alternatively, you could do this from inside the Jupyter notebook (or Python script):
```python
import os
os.environ["OPENAI_API_KEY"] = "..."
```
## Building a Language Model Application
Now that we have installed LangChain and set up our environment, we can start building our language model application.
LangChain provides many modules that can be used to build language model applications. Modules can be combined to create more complex applications, or be used individually for simple applications.
`````{dropdown} LLMs: Get predictions from a language model
The most basic building block of LangChain is calling an LLM on some input.
Let's walk through a simple example of how to do this.
For this purpose, let's pretend we are building a service that generates a company name based on what the company makes.
In order to do this, we first need to import the LLM wrapper.
```python
from langchain.llms import OpenAI
```
We can then initialize the wrapper with any arguments.
In this example, we probably want the outputs to be MORE random, so we'll initialize it with a HIGH temperature.
```python
llm = OpenAI(temperature=0.9)
```
We can now call it on some input!
```python
text = "What would be a good company name a company that makes colorful socks?"
print(llm(text))
```
```pycon
Feetful of Fun
```
For more details on how to use LLMs within LangChain, see the [LLM getting started guide](../modules/llms/getting_started.ipynb).
`````
`````{dropdown} Prompt Templates: Manage prompts for LLMs
Calling an LLM is a great first step, but it's just the beginning.
Normally when you use an LLM in an application, you are not sending user input directly to the LLM.
Instead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.
For example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.
In this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.
This is easy to do with LangChain!
First lets define the prompt template:
```python
from langchain.prompts import PromptTemplate
prompt = PromptTemplate(
input_variables=["product"],
template="What is a good name for a company that makes {product}?",
)
```
Let's now see how this works! We can call the `.format` method to format it.
```python
print(prompt.format(product="colorful socks"))
```
```pycon
What is a good name for a company that makes colorful socks?
```
[For more details, check out the getting started guide for prompts.](../modules/prompts/getting_started.ipynb)
`````
`````{dropdown} Chains: Combine LLMs and prompts in multi-step workflows
Up until now, we've worked with the PromptTemplate and LLM primitives by themselves. But of course, a real application is not just one primitive, but rather a combination of them.
A chain in LangChain is made up of links, which can be either primitives like LLMs or other chains.
The most core type of chain is an LLMChain, which consists of a PromptTemplate and an LLM.
Extending the previous example, we can construct an LLMChain which takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM.
```python
from langchain.prompts import PromptTemplate
from langchain.llms import OpenAI
llm = OpenAI(temperature=0.9)
prompt = PromptTemplate(
input_variables=["product"],
template="What is a good name for a company that makes {product}?",
)
```
We can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:
```python
from langchain.chains import LLMChain
chain = LLMChain(llm=llm, prompt=prompt)
```
Now we can run that chain only specifying the product!
```python
chain.run("colorful socks")
# -> '\n\nSocktastic!'
```
There we go! There's the first chain - an LLM Chain.
This is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.
[For more details, check out the getting started guide for chains.](../modules/chains/getting_started.ipynb)
`````
`````{dropdown} Agents: Dynamically call chains based on user input
So for the chains we've looked at run in a predetermined order.
Agents no longer do: they use an LLM to determine which actions to take and in what order. An action can either be using a tool and observing its output, or returning to the user.
When used correctly agents can be extremely powerful. In this tutorial, we show you how to easily use agents through the simplest, highest level API.
In order to load agents, you should understand the following concepts:
- Tool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.
- LLM: The language model powering the agent.
- Agent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see the documentation for custom agents (coming soon).
**Agents**: For a list of supported agents and their specifications, see [here](../modules/agents/agents.md).
**Tools**: For a list of predefined tools and their specifications, see [here](../modules/agents/tools.md).
```python
from langchain.agents import load_tools
from langchain.agents import initialize_agent
from langchain.llms import OpenAI
# First, let's load the language model we're going to use to control the agent.
llm = OpenAI(temperature=0)
# Next, let's load some tools to use. Note that the `llm-math` tool uses an LLM, so we need to pass that in.
tools = load_tools(["serpapi", "llm-math"], llm=llm)
# Finally, let's initialize an agent with the tools, the language model, and the type of agent we want to use.
agent = initialize_agent(tools, llm, agent="zero-shot-react-description", verbose=True)
# Now let's test it out!
agent.run("Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?")
```
```pycon
Entering new AgentExecutor chain...
I need to find out who Olivia Wilde's boyfriend is and then calculate his age raised to the 0.23 power.
Action: Search
Action Input: "Olivia Wilde boyfriend"
Observation: Jason Sudeikis
Thought: I need to find out Jason Sudeikis' age
Action: Search
Action Input: "Jason Sudeikis age"
Observation: 47 years
Thought: I need to calculate 47 raised to the 0.23 power
Action: Calculator
Action Input: 47^0.23
Observation: Answer: 2.4242784855673896
Thought: I now know the final answer
Final Answer: Jason Sudeikis, Olivia Wilde's boyfriend, is 47 years old and his age raised to the 0.23 power is 2.4242784855673896.
> Finished AgentExecutor chain.
"Jason Sudeikis, Olivia Wilde's boyfriend, is 47 years old and his age raised to the 0.23 power is 2.4242784855673896."
```
`````
`````{dropdown} Memory: Add state to chains and agents
So far, all the chains and agents we've gone through have been stateless. But often, you may want a chain or agent to have some concept of "memory" so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of "short-term memory". On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of "long-term memory". For more concrete ideas on the latter, see this [awesome paper](https://memprompt.com/).
LangChain provides several specially created chains just for this purpose. This notebook walks through using one of those chains (the `ConversationChain`) with two different types of memory.
By default, the `ConversationChain` has a simple type of memory that remembers all previous inputs/outputs and adds them to the context that is passed. Let's take a look at using this chain (setting `verbose=True` so we can see the prompt).
```python
from langchain import OpenAI, ConversationChain
llm = OpenAI(temperature=0)
conversation = ConversationChain(llm=llm, verbose=True)
conversation.predict(input="Hi there!")
```
```pycon
> Entering new chain...
Prompt after formatting:
The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.
Current conversation:
Human: Hi there!
AI:
> Finished chain.
' Hello! How are you today?'
```
```python
conversation.predict(input="I'm doing well! Just having a conversation with an AI.")
```
```pycon
> Entering new chain...

This library is aimed at assisting in the development of those types of applications. This library is aimed at assisting in the development of those types of applications.
There are six main areas that LangChain is designed to help with. Getting Started
These are, in increasing order of complexity: ----------------
1. LLM and Prompts Checkout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.
2. Chains
3. Data Augmented Generation
4. Agents
5. Memory
6. [BETA] Evaluation
Let's go through these categories and for each one identify key concepts (to clarify terminology) as well as the problems in this area LangChain helps solve.
**🦜 LLMs and Prompts**
Calling out to an LLM once is pretty easy, with most of them being behind well documented APIs.
However, there are still some challenges going from that to an application running in production that LangChain attempts to address.
*Key Concepts*
- LLM: A large language model, in particular a text-to-text model.
- Prompt: The input to a language model. Typically this is not simply a hardcoded string but rather a combination of a template, some examples, and user input.
- Prompt Template: An object responsible for constructing the final prompt to pass to a LLM.
*Problems Solved*
- Switching costs: by exposing a standard interface for all the top LLM providers, LangChain makes it easy to switch from one provider to another, whether it be for production use cases or just for testing stuff out.
- Prompt management: managing your prompts is easy when you only have one simple one, but can get tricky when you have a bunch or when they start to get more complex. LangChain provides a standard way for storing, constructing, and referencing prompts.
- Prompt optimization: despite the underlying models getting better and better, there is still currently a need for carefully constructing prompts.
**🔗️ Chains**
Using an LLM in isolation is fine for some simple applications, but many more complex ones require chaining LLMs - either with eachother or with other experts.
LangChain provides several parts to help with that.
*Key Concepts*
- Tools: APIs designed for assisting with a particular use case (search, databases, Python REPL, etc). Prompt templates, LLMs, and chains can also be considered tools.
- Chains: A combination of multiple tools in a deterministic manner.
*Problems Solved*
- Standard interface for working with Chains
- Easy way to construct chains of LLMs
- Lots of integrations with other tools that you may want to use in conjunction with LLMs
- End-to-end chains for common workflows (database question/answer, api calling, etc)
**📚 Data Augmented Generation**
LLMs have access to all the data they were trained on, but there are still large chunks of data they were not trained on.
Data Augmented Generation covers how to use LLMs to generate text conditioning on data outside of what the LLM was trained on.
*Key Concepts*
- Documents: A document is a piece of text, along with some associated metadata, that can be inserted into the context of a query to condition generation on that text.
- Embeddings: A vector representation of text (or other unstructured data). Useful for being able to numerically compare pieces of text.
- Vectorstore: A database which stores embeddings and can be searched over.
*Problems Solved*
- Standard interface for working with Documents, Embeddings, and Vectorstores
- Lots of integrations with common embedding providers and vectorstores
- End-to-end chains for common workflows (recursive summarization, question answering over documents, etc)
**🤖 Agents**
Some applications will require not just a predetermined chain of calls to LLMs/other tools, but potentially an unknown chain that depends on the user input.
In these types of chains, there is a “agent” which has access to a suite of tools.
Depending on the user input, the agent can then decide which, if any, of these tools to call.
*Key Concepts*
- Tools: same as above.
- Agent: An LLM-powered class responsible for determining which tools to use and in what order.
*Problems Solved*
- Standard agent interfaces
- A selection of powerful agents to choose from
- Common chains that can be used as tools
**🧠 Memory**
By default, Chains and Agents are stateless, meaning that they treat each incoming query independently.
In some applications (chatbots being a GREAT example) it is highly important to remember previous interactions,
both at a short term but also at a long term level. The concept of "Memory" exists to do exactly that.
*Key Concepts*
- Memory: A class that can be added to an Agent or Chain to (1) pull in memory variables before calling that chain/agent, and (2) create new memories after the chain/agent finishes.
- Memory Variables: Variables returned from a Memory class, to be passed into the chain/agent along with the user input.
*Problems Solved*
- Standard memory interfaces
- A collection of common memory implementations to choose from
- Common chains/agents that use memory (e.g. chatbots)
**🧐 Evaluation:**
[BETA] Generative models are notoriously hard to evaluate with traditional metrics.
One new way of evaluating them is using language models themselves to do the evaluation.
LangChain provides some prompts/chains for assisting in this.
This is still in Beta, which also means that feedback is especially appreciated here.

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:
- `Prompts <modules/prompts.html>`_: This includes prompt management, prompt optimization, and prompt serialization.
- `LLMs <modules/llms.html>`_: This includes a generic interface for all LLMs, and common utilities for working with LLMs.
- `Utils <modules/utils.html>`_: Language models are often more powerful when interacting with other sources of knowledge or computation. This can include Python REPLs, embeddings, search engines, and more. LangChain provides a large collection of common utils to use in your application.
- `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.
- `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.
- `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.

How-To Guides
=============
The first category of how-to guides here cover specific parts of working with agents.
`Custom Tools <examples/custom_tools.html>`_: How to create custom tools that an agent can use.
`Intermediate Steps <examples/intermediate_steps.html>`_: How to access and use intermediate steps to get more visibility into the internals of an agent.
`Custom Agent <examples/custom_agent.html>`_: How to create a custom agent (specifically, a custom LLM + prompt to drive that agent).
`Multi Input Tools <examples/multi_input_tool.html>`_: How to use a tool that requires multiple inputs with an agent.
`Search Tools <examples/search_tools.html>`_: How to use the different type of search tools that LangChain supports.
`Max Iterations <examples/max_iterations.html>`_: How to restrict an agent to a certain number of iterations.
The next set of examples are all end-to-end agents for specific applications.
In all examples there is an Agent with a particular set of tools.
- Tools: A tool can be anything that takes in a string and returns a string. This means that you can use both the primitives AND the chains found in `this <chains.html>`_ documentation. LangChain also provides a list of easily loadable tools. For detailed information on those, please see `this documentation <../explanation/tools.html>`_
- Agents: An agent uses an LLMChain to determine which tools to use. For a list of all available agent types, see `here <../explanation/agents.html>`_.
**MRKL**
- **Tools used**: Search, SQLDatabaseChain, LLMMathChain
- **Agent used**: `zero-shot-react-description`
- `Paper <https://arxiv.org/pdf/2205.00445.pdf>`_
- **Note**: This is the most general purpose example, so if you are looking to use an agent with arbitrary tools, please start here.
- `Example Notebook <implementations/mrkl.html>`_
**Self-Ask-With-Search**
- **Tools used**: Search
- **Agent used**: `self-ask-with-search`
- `Paper <https://ofir.io/self-ask.pdf>`_
- `Example Notebook <implementations/self_ask_with_search.html>`_
**ReAct**
- **Tools used**: Wikipedia Docstore
- **Agent used**: `react-docstore`
- `Paper <https://arxiv.org/pdf/2210.03629.pdf>`_
- `Example Notebook <implementations/react.html>`_

# Key Concepts
## Agents
Agents use an LLM to determine which actions to take and in what order.
For more detailed information on agents, and different types of agents in LangChain, see [this documentation](agents.md).
## Tools
Tools are functions that agents can use to interact with the world.
These tools can be generic utilities (e.g. search), other chains, or even other agents.
For more detailed information on tools, and different types of tools in LangChain, see [this documentation](tools.md).

Chains
==========================
Using an LLM in isolation is fine for some simple applications,
but many more complex ones require chaining LLMs - either with eachother or with other experts.
LangChain provides a standard interface for Chains, as well as some common implementations of chains for easy use.
The following sections of documentation are provided:
- `Getting Started <chains/getting_started.html>`_: A getting started guide for chains, to get you up and running quickly.
- `Key Concepts <chains/key_concepts.html>`_: A conceptual guide going over the various concepts related to chains.
- `How-To Guides <chains/how_to_guides.html>`_: A collection of how-to guides. These highlight how to use various types of chains.
- `Reference </reference/chains.html>`_: API reference documentation for all Chain classes.

# CombineDocuments Chains
CombineDocuments chains are useful for when you need to run a language over multiple documents.
Common use cases for this include question answering, question answering with sources, summarization, and more.
For more information on specific use cases as well as different methods for **fetching** these documents, please see
[this overview](/use_cases/combine_docs.md).
This documentation now picks up from after you've fetched your documents - now what?
How do you pass them to the language model in a format it can understand?
There are a few different methods, or chains, for doing so. LangChain supports three of the more common ones - and
we are actively looking to include more, so if you have any ideas please reach out! Note that there is not
one best method - the decision of which one to use is often very context specific. In order from simplest to
most complex:
## Stuffing
Stuffing is the simplest method, whereby you simply stuff all the related data into the prompt as context
to pass to the language model. This is implemented in LangChain as the `StuffDocumentsChain`.
**Pros:** Only makes a single call to the LLM. When generating text, the LLM has access to all the data at once.
**Cons:** Most LLMs have a context length, and for large documents (or many documents) this will not work as it will result in a prompt larger than the context length.
The main downside of this method is that it only works one smaller pieces of data. Once you are working
with many pieces of data, this approach is no longer feasible. The next two approaches are designed to help deal with that.
## Map Reduce
This method involves an initial prompt on each chunk of data (for summarization tasks, this
could be a summary of that chunk; for question-answering tasks, it could be an answer based solely on that chunk).
Then a different prompt is run to combine all the initial outputs. This is implemented in the LangChain as the `MapReduceDocumentsChain`.
**Pros:** Can scale to larger documents (and more documents) than `StuffDocumentsChain`. The calls to the LLM on individual documents are independent and can therefore be parallelized.
**Cons:** Requires many more calls to the LLM than `StuffDocumentsChain`. Loses some information during the final combining call.
## Refine
This method involves an initial prompt on the first chunk of data, generating some output.
For the remaining documents, that output is passed in, along with the next document,
asking the LLM to refine the output based on the new document.
**Pros:** Can pull in more relevant context, and may be less lossy than `MapReduceDocumentsChain`.
**Cons:** Requires many more calls to the LLM than `StuffDocumentsChain`. The calls are also NOT independent, meaning they cannot be paralleled like `MapReduceDocumentsChain`. There is also some potential dependencies on the ordering of the documents.

CombineDocuments Chains
-----------------------
A chain is made up of links, which can be either primitives or other chains.
Primitives can be either `prompts <../prompts.html>`_, `llms <../llms.html>`_, `utils <../utils.html>`_, or other chains.
The examples here are all end-to-end chains for working with documents.
`Question Answering <combine_docs_examples/question_answering.html>`_: A walkthrough of how to use LangChain for question answering over specific documents.
`Question Answering with Sources <combine_docs_examples/qa_with_sources.html>`_: A walkthrough of how to use LangChain for question answering (with sources) over specific documents.
`Summarization <combine_docs_examples/summarize.html>`_: A walkthrough of how to use LangChain for summarization over specific documents.
`Vector DB Question Answering <combine_docs_examples/vector_db_qa.html>`_: A walkthrough of how to use LangChain for question answering over a vector database.

Generic Chains
--------------
A chain is made up of links, which can be either primitives or other chains.
Primitives can be either `prompts <../prompts.html>`_, `llms <../llms.html>`_, `utils <../utils.html>`_, or other chains.
The examples here are all generic end-to-end chains that are meant to be used to construct other chains rather than serving a specific purpose.
**LLMChain**
- **Links Used**: PromptTemplate, LLM
- **Notes**: This chain is the simplest chain, and is widely used by almost every other chain. This chain takes arbitrary user input, creates a prompt with it from the PromptTemplate, passes that to the LLM, and then returns the output of the LLM as the final output.
- `Example Notebook <generic/llm_chain.html>`_
**Transformation Chain**
- **Links Used**: TransformationChain
- **Notes**: This notebook shows how to use the Transformation Chain, which takes an arbitrary python function and applies it to inputs/outputs of other chains.
- `Example Notebook <generic/transformation.html>`_
**Sequential Chain**
- **Links Used**: Sequential
- **Notes**: This notebook shows how to combine calling multiple other chains in sequence.
- `Example Notebook <generic/sequential_chains.html>`_

How-To Guides
=============
A chain is made up of links, which can be either primitives or other chains.
Primitives can be either `prompts <../prompts.html>`_, `llms <../llms.html>`_, `utils <../utils.html>`_, or other chains.
The examples here are all end-to-end chains for specific applications.
They are broken up into three categories:
1. `Generic Chains <generic_how_to.html>`_: Generic chains, that are meant to help build other chains rather than serve a particular purpose.
2. `CombineDocuments Chains <combine_docs_how_to.html>`_: Chains aimed at making it easy to work with documents (question answering, summarization, etc).
3. `Utility Chains <utility_how_to.html>`_: Chains consisting of an LLMChain interacting with a specific util.

# Key Concepts
## Chains
A chain is made up of links, which can be either primitives or other chains.
They vary greatly in complexity and are combination of generic, highly configurable pipelines and more narrow (but usually more complex) pipelines.
## Sequential Chain
This is a specific type of chain where multiple other chains are run in sequence, with the outputs being added as inputs
to the next. A subtype of this type of chain is the `SimpleSequentialChain`, where all subchains have only one input and one output,
and the output of one is therefor used as sole input to the next chain.
## CombineDocuments Chains
These are a subset of chains designed to work with documents. There are two pieces to consider:
1. The underlying chain method (eg, how the documents are combined)
2. Use cases for these types of chains.
For the first, please see [this documentation](combine_docs.md) for more detailed information on the types of chains LangChain supports.
For the second, please see the Use Cases section for more information on [question answering](/use_cases/question_answering.md),
[question answering with sources](/use_cases/qa_with_sources.md), and [summarization](/use_cases/summarization.md).

Utility Chains
--------------
A chain is made up of links, which can be either primitives or other chains.
Primitives can be either `prompts <../prompts.html>`_, `llms <../llms.html>`_, `utils <../utils.html>`_, or other chains.
The examples here are all end-to-end chains for specific applications, focused on interacting an LLMChain with a specific utility.
**LLMMath**
- **Links Used**: Python REPL, LLMChain
- **Notes**: This chain takes user input (a math question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.
- `Example Notebook <examples/llm_math.html>`_
**PAL**
- **Links Used**: Python REPL, LLMChain
- **Notes**: This chain takes user input (a reasoning question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.
- `Paper <https://arxiv.org/abs/2211.10435>`_
- `Example Notebook <examples/pal.html>`_
**SQLDatabase Chain**
- **Links Used**: SQLDatabase, LLMChain
- **Notes**: This chain takes user input (a question), uses a first LLM chain to construct a SQL query to run against the SQL database, and then uses another LLMChain to take the results of that query and use it to answer the original question.
- `Example Notebook <examples/sqlite.html>`_
**LLMBash Chain**
- **Links Used**: BashProcess, LLMChain
- **Notes**: This chain takes user input (a question), uses an LLM chain to convert it to a bash command to run in the terminal, and then returns that as the result.
- `Example Notebook <examples/llm_bash.html>`_
**LLMChecker Chain**
- **Links Used**: LLMChain
- **Notes**: This chain takes user input (a question), uses an LLM chain to answer that question, and then uses other LLMChains to self-check that answer.
- `Example Notebook <examples/llm_checker.html>`_
**LLMRequests Chain**
- **Links Used**: Requests, LLMChain
- **Notes**: This chain takes a URL and other inputs, uses Requests to get the data at that URL, and then passes that along with the other inputs into an LLMChain to generate a response. The example included shows how to ask a question to Google - it firsts constructs a Google url, then fetches the data there, then passes that data + the original question into an LLMChain to get an answer.
- `Example Notebook <examples/llm_requests.html>`_
**Moderation Chain**
- **Links Used**: LLMChain, ModerationChain
- **Notes**: This chain shows how to use OpenAI's content moderation endpoint to screen output, and shows how to connect this to an LLMChain.
- `Example Notebook <examples/moderation.html>`_

LLMs
==========================
Large Language Models (LLMs) are a core component of LangChain.
LangChain is a provider of LLMs, but rather provides a standard interface through which
you can interact with a variety of LLMs.
The following sections of documentation are provided:
- `Getting Started <llms/getting_started.html>`_: An overview of all the functionality the LangChain LLM class provides.
- `Key Concepts <llms/key_concepts.html>`_: A conceptual guide going over the various concepts related to LLMs.
- `How-To Guides <llms/how_to_guides.html>`_: A collection of how-to guides. These highlight how to accomplish various objectives with our LLM class, as well as how to integrate with various LLM providers.
- `Reference </reference/modules/llms.html>`_: API reference documentation for all LLM classes.

# Key Concepts
## LLMs
Wrappers around Large Language Models (in particular, the "generate" ability of large language models) are at the core of LangChain functionality.
The core method that these classes expose is a `generate` method, which takes in a list of strings and returns an LLMResult (which contains outputs for all input strings).
Read more about LLMResult. This interface operates over a list of strings because often the lists of strings can be batched to the LLM provider,
providing speed and efficiency gains.
For convenience, this class also exposes a simpler, more user friendly interface (via `__call__`).
The interface for this takes in a single string, and returns a single string.
## Generation
The output of a single generation. Currently in LangChain this is just the generated text, although could be extended in the future
to contain log probs or the like.
## LLMResult
The full output of a call to the `generate` method of the LLM class.
Since the `generate` method takes as input a list of strings, this returns a list of results.
Each result consists of a list of generations (since you can request N generations per input string).
This also contains a `llm_output` attribute which contains provider-specific information about the call.

Memory
==========================
By default, Chains and Agents are stateless,
meaning that they treat each incoming query independently.
In some applications (chatbots being a GREAT example) it is highly important
to remember previous interactions, both at a short term but also at a long term level.
The concept of “Memory” exists to do exactly that.
The following sections of documentation are provided:
- `Getting Started <memory/getting_started.html>`_: An overview of how to get started with different types of memory.
- `Key Concepts <memory/key_concepts.html>`_: A conceptual guide going over the various concepts related to memory.
- `How-To Guides <memory/how_to_guides.html>`_: A collection of how-to guides. These highlight how to work with different types of memory, as well as how to customize memory.

"# Conversational Memory Customization\n",
"\n",
"This notebook walks through a few ways to customize conversational memory.\n",
"\n",
"The main way to do so is by changing the AI prefix in the conversation summary. By default, this is set to \"AI\", but you can set this to be anything you want. Note that if you change this, you should also change the prompt used in the chain to reflect this naming change. Let's walk through an example of that in the example below."

# Key Concepts
## Memory
By default, Chains and Agents are stateless, meaning that they treat each incoming query independently.
In some applications (chatbots being a GREAT example) it is highly important to remember previous interactions,
both at a short term but also at a long term level. The concept of "Memory" exists to do exactly that.
## Conversational Memory
One of the simpler forms of memory occurs in chatbots, where they remember previous conversations.
There are a few different ways to accomplish this:
- Buffer: This is just passing in the past `N` interactions in as context. `N` can be chosen based on a fixed number, the length of the interactions, or other!
- Summary: This involves summarizing previous conversations and passing that summary in, instead of the raw dialouge itself. Compared to `Buffer`, this compresses information: meaning it is more lossy, but also less likely to run into context length limits.
- Combination: A combination of the above two approaches, where you compute a summary but also pass in some previous interfactions directly!
