# Using Docker
|
||||
|
||||
To quickly get started, run the command `make docker`.
|
||||
|
||||
If docker is installed the Makefile will export extra targets in the fomrat `docker.*` to build and run the docker image. Type `make` for a list of available tasks.
|
||||
|
||||
There is a basic `docker-compose.yml` in the docker directory.
|
||||
|
||||
## Building the development image
|
||||
|
||||
Using `make docker` will build the dev image if it does not exist, then drops
|
||||
you inside the container with the langchain environment available in the shell.
|
||||
|
||||
### Customizing the image and installed dependencies
|
||||
|
||||
The image is built with a default python version and all extras and dev
|
||||
dependencies. It can be customized by changing the variables in the [.env](/docker/.env)
|
||||
file.
|
||||
|
||||
If you don't need all the `extra` dependencies a slimmer image can be obtained by
|
||||
commenting out `POETRY_EXTRA_PACKAGES` in the [.env](docker/.env) file.
|
||||
|
||||
### Image caching
|
||||
|
||||
The Dockerfile is optimized to cache the poetry install step. A rebuild is triggered when there a change to the source code.
|
||||
|
||||
## Example Usage
|
||||
|
||||
All commands from langchain's python environment are available by default in the container.
|
||||
|
||||
A few examples:
|
||||
```bash
|
||||
# run jupyter notebook
|
||||
docker run --rm -it IMG jupyter notebook
|
||||
|
||||
# run ipython
|
||||
docker run --rm -it IMG ipython
|
||||
|
||||
# start web server
|
||||
docker run --rm -p 8888:8888 IMG python -m http.server 8888
|
||||
```
|
||||
|
||||
## Testing / Linting
|
||||
|
||||
Tests and lints are run using your local source directory that is mounted on the volume /src.
|
||||
|
||||
Run unit tests in the container with `make docker.test`.
|
||||
|
||||
Run the linting and formatting checks with `make docker.lint`.
|
||||
|
||||
Note: this task can run in parallel using `make -j4 docker.lint`.

# Deployments
|
||||
|
||||
So you've made a really cool chain - now what? How do you deploy it and make it easily sharable with the world?
|
||||
|
||||
This section covers several options for that.
|
||||
Note that these are meant as quick deployment options for prototypes and demos, and not for production systems.
|
||||
If you are looking for help with deployment of a production system, please contact us directly.
|
||||
|
||||
What follows is a list of template GitHub repositories aimed that are intended to be
|
||||
very easy to fork and modify to use your chain.
|
||||
This is far from an exhaustive list of options, and we are EXTREMELY open to contributions here.
|
||||
|
||||

### VectorStore
|
||||
|
||||
There exists a wrapper around the Atlas neural database, allowing you to use it as a vectorstore.
|
||||
This vectorstore also gives you full access to the underlying AtlasProject object, which will allow you to use the full range of Atlas map interactions, such as bulk tagging and automatic topic modeling.
|
||||
Please see [the Nomic docs](https://docs.nomic.ai/atlas_api.html) for more detailed information.
|
||||

# Banana
|
||||
|
||||
This page covers how to use the Banana ecosystem within LangChain.
|
||||
It is broken into two parts: installation and setup, and then references to specific Banana wrappers.
|
||||
|
||||
## Installation and Setup
|
||||
|
||||
- Install with `pip3 install banana-dev`
|
||||
- Get an Banana api key and set it as an environment variable (`BANANA_API_KEY`)
|
||||
|
||||
## Define your Banana Template
|
||||
|
||||
If you want to use an available language model template you can find one [here](https://app.banana.dev/templates/conceptofmind/serverless-template-palmyra-base).
|
||||
This template uses the Palmyra-Base model by [Writer](https://writer.com/product/api/).
|
||||
You can check out an example Banana repository [here](https://github.com/conceptofmind/serverless-template-palmyra-base).
|
||||
|
||||
## Build the Banana app
|
||||
|
||||
Banana Apps must include the "output" key in the return json.
|
||||
There is a rigid response structure.
|
||||
|
||||
```python
|
||||
# Return the results as a dictionary
|
||||
result = {'output': result}
|
||||
```
|
||||
|
||||
An example inference function would be:
|
||||
|
||||
```python
|
||||
def inference(model_inputs:dict) -> dict:
|
||||
global model
|
||||
global tokenizer
|
||||
|
||||
# Parse out your arguments
|
||||
prompt = model_inputs.get('prompt', None)
|
||||
if prompt == None:
|
||||
return {'message': "No prompt provided"}
|
||||
|
||||
# Run the model
|
||||
input_ids = tokenizer.encode(prompt, return_tensors='pt').cuda()
|
||||
output = model.generate(
|
||||
input_ids,
|
||||
max_length=100,
|
||||
do_sample=True,
|
||||
top_k=50,
|
||||
top_p=0.95,
|
||||
num_return_sequences=1,
|
||||
temperature=0.9,
|
||||
early_stopping=True,
|
||||
no_repeat_ngram_size=3,
|
||||
num_beams=5,
|
||||
length_penalty=1.5,
|
||||
repetition_penalty=1.5,
|
||||
bad_words_ids=[[tokenizer.encode(' ', add_prefix_space=True)[0]]]
|
||||
)
|
||||
|
||||
result = tokenizer.decode(output[0], skip_special_tokens=True)
|
||||
# Return the results as a dictionary
|
||||
result = {'output': result}
|
||||
return result
|
||||
```
|
||||
|
||||

||||
|
||||
## Tracing and Monitoring
|
||||
|
||||
Graphsignal automatically instruments and starts tracing and monitoring chains. Traces, metrics and errors are then available in your [Graphsignal dashboard](https://app.graphsignal.com/). No prompts or other sensitive data are sent to Graphsignal cloud, only statistics and metadata.
|
||||
|
||||
Initialize the tracer by providing a deployment name:
|
||||
|
||||
```python
|
||||
import graphsignal
|
||||
|
||||
graphsignal.configure(deployment='my-langchain-app-prod')
|
||||
```
|
||||
|
||||
In order to trace full runs and see a breakdown by chains and tools, you can wrap the calling routine or use a decorator:
|
||||
|
||||
```python
|
||||
with graphsignal.start_trace('my-chain'):
|
||||
chain.run("some initial text")
|
||||
```
|
||||
|
||||
Optionally, enable profiling to record function-level statistics for each trace.
|
||||
|
||||
```python
|
||||
with graphsignal.start_trace(
|
||||
'my-chain', options=graphsignal.TraceOptions(enable_profiling=True)):
|
||||
chain.run("some initial text")
|
||||
```
|
||||

||||
- Create a PromptLayer account
|
||||
- Create an api token and set it as an environment variable (`PROMPTLAYER_API_KEY`)
|
||||
|
||||
## Wrappers
|
||||
|
||||
### LLM
|
||||
|
||||
There exists an PromptLayer OpenAI LLM wrapper, which you can access with
|
||||
```python
|
||||
from langchain.llms import PromptLayerOpenAI
|
||||
```
|
||||
|
||||
To tag your requests, use the argument `pl_tags` when instanializing the LLM
|
||||
```python
|
||||
from langchain.llms import PromptLayerOpenAI
|
||||
llm = PromptLayerOpenAI(pl_tags=["langchain-requests", "chatbot"])
|
||||
```
|
||||
|
||||
This LLM is identical to the [OpenAI LLM](./openai), except that
|
||||
- all your requests will be logged to your PromptLayer account
|
||||
- you can add `pl_tags` when instantializing to tag your requests on PromptLayer

||||
It is broken into two parts: installation and setup, and then references to the specific SearxNG API wrapper.
|
||||
|
||||
## Installation and Setup
|
||||
|
||||
- You can find a list of public SearxNG instances [here](https://searx.space/).
|
||||
- It recommended to use a self-hosted instance to avoid abuse on the public instances. Also note that public instances often have a limit on the number of requests.
|
||||
- To run a self-hosted instance see [this page](https://searxng.github.io/searxng/admin/installation.html) for more information.
|
||||
- To use the tool you need to provide the searx host url by:
|
||||
1. passing the named parameter `searx_host` when creating the instance.
|
||||
2. exporting the environment variable `SEARXNG_HOST`.

# Unstructured
|
||||
|
||||
This page covers how to use the [`unstructured`](https://github.com/Unstructured-IO/unstructured)
|
||||
ecosystem within LangChain. The `unstructured` package from
|
||||
[Unstructured.IO](https://www.unstructured.io/) extracts clean text from raw source documents like
|
||||
PDFs and Word documents.
|
||||
|
||||
|
||||
This page is broken into two parts: installation and setup, and then references to specific
|
||||
`unstructured` wrappers.
|
||||
|
||||
## Installation and Setup
|
||||
- Install the Python SDK with `pip install "unstructured[local-inference]"`
|
||||
- Install the following system dependencies if they are not already available on your system.
|
||||
Depending on what document types you're parsing, you may not need all of these.
|
||||
- `libmagic-dev`
|
||||
- `poppler-utils`
|
||||
- `tesseract-ocr`
|
||||
- `libreoffice`
|
||||
- If you are parsing PDFs, run the following to install the `detectron2` model, which
|
||||
`unstructured` uses for layout detection:
|
||||
- `pip install "detectron2@git+https://github.com/facebookresearch/detectron2.git@v0.6#egg=detectron2"`
|
||||
|
||||
## Wrappers
|
||||
|
||||
### Data Loaders
|
||||
|
||||
The primary `unstructured` wrappers within `langchain` are data loaders. The following
|
||||
shows how to use the most basic unstructured data loader. There are other file-specific
|
||||
data loaders available in the `langchain.document_loaders` module.
|
||||
|
||||
```python
|
||||
from langchain.document_loaders import UnstructuredFileLoader
|
||||
|
||||
loader = UnstructuredFileLoader("state_of_the_union.txt")
|
||||
loader.load()
|
||||
```
|
||||
|
||||
If you instantiate the loader with `UnstructuredFileLoader(mode="elements")`, the loader
|
||||
will track additional metadata like the page number and text type (i.e. title, narrative text)
|
||||
when that information is available.

# 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 far 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).
|
||||
|
||||
For this example, you will also need to install the SerpAPI Python package.
|
||||
|
||||
```bash
|
||||
pip install google-search-results
|
||||
```
|
||||
|
||||
And set the appropriate environment variables.
|
||||
|
||||
```python
|
||||
import os
|
||||
os.environ["SERPAPI_API_KEY"] = "..."
|
||||
```
|
||||
|
||||
Now we can get started!
|
||||
|
||||
```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!

```
|
||||
|

`````{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)
|
||||

Welcome to LangChain
|
||||
==========================
|
||||
|
||||
Large language models (LLMs) are emerging as a transformative technology, enabling
|
||||
developers to build applications that they previously could not.
|
||||
But using these LLMs in isolation is often not enough to
|
||||
create a truly powerful app - the real power comes when you are able to
|
||||
combine them with other sources of computation or knowledge.
|
||||
|
||||
This library is aimed at assisting in the development of those types of applications. Common examples of these types of applications include:
|
||||
|
||||
**❓ Question Answering over specific documents**
|
||||
|
||||
- `Documentation <./use_cases/question_answering.html>`_
|
||||
- End-to-end Example: `Question Answering over Notion Database <https://github.com/hwchase17/notion-qa>`_
|
||||
|
||||
**💬 Chatbots**
|
||||
|
||||
- `Documentation <./use_cases/chatbots.html>`_
|
||||
- End-to-end Example: `Chat-LangChain <https://github.com/hwchase17/chat-langchain>`_
|
||||
|
||||
**🤖 Agents**
|
||||
|
||||
- `Documentation <./use_cases/agents.html>`_
|
||||

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:
|
||||
|
||||
|
||||
- `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.
|
||||
|
||||
- `Document Loaders <./modules/document_loaders.html>`_: This includes a standard interface for loading documents, as well as specific integrations to all types of text data sources.
|
||||
|
||||
- `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.
|
||||
|
||||
- `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.
|
||||
|
||||
- `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.

Use Cases
|
||||
----------
|
||||
|
||||
The above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.
|
||||
|
||||
- `Agents <./use_cases/agents.html>`_: Agents are systems that use a language model to interact with other tools. These can be used to do more grounded question/answering, interact with APIs, or even take actions.
|
||||
|
||||
- `Chatbots <./use_cases/chatbots.html>`_: Since language models are good at producing text, that makes them ideal for creating chatbots.
|
||||
|
||||
- `Data Augmented Generation <./use_cases/combine_docs.html>`_: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.
|
||||
|
||||
- `Question Answering <./use_cases/question_answering.html>`_: Answering questions over specific documents, only utilizing the information in those documents to construct an answer. A type of Data Augmented Generation.
|
||||
|
||||
- `Summarization <./use_cases/summarization.html>`_: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.
|
||||
|
||||
- `Evaluation <./use_cases/evaluation.html>`_: 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.
|
||||
|
||||
- `Generate similar examples <./use_cases/generate_examples.html>`_: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.
|
||||
|
||||
- `Compare models <./use_cases/model_laboratory.html>`_: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.

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's 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.
|
||||
|
||||
The following sections of documentation are provided:
|
||||
|
||||
- `Getting Started <./agents/getting_started.html>`_: A notebook to help you get started working with agents as quickly as possible.
|
||||
|
||||
- `Key Concepts <./agents/key_concepts.html>`_: A conceptual guide going over the various concepts related to agents.
|
||||
|
||||
- `How-To Guides <./agents/how_to_guides.html>`_: A collection of how-to guides. These highlight how to integrate various types of tools, how to work with different types of agents, and how to customize agents.
|
||||
|
||||
- `Reference <../reference/modules/agents.html>`_: API reference documentation for all Agent classes.

# Agents
|
||||
|
||||
Agents 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 a response to the user.
|
||||
For a list of easily loadable tools, see [here](tools.md).
|
||||
Here are the agents available in LangChain.
|
||||
|
||||
For a tutorial on how to load agents, see [here](getting_started.ipynb).
|
||||
|
||||
## `zero-shot-react-description`
|
||||
|
||||
This agent uses the ReAct framework to determine which tool to use
|
||||
based solely on the tool's description. Any number of tools can be provided.
|
||||
This agent requires that a description is provided for each tool.
|
||||
|
||||
## `react-docstore`
|
||||
|
||||
This agent uses the ReAct framework to interact with a docstore. Two tools must
|
||||
be provided: a `Search` tool and a `Lookup` tool (they must be named exactly as so).
|
||||
The `Search` tool should search for a document, while the `Lookup` tool should lookup
|
||||
a term in the most recently found document.
|
||||
This agent is equivalent to the
|
||||
original [ReAct paper](https://arxiv.org/pdf/2210.03629.pdf), specifically the Wikipedia example.
|
||||
|
||||
## `self-ask-with-search`
|
||||
|
||||
This agent utilizes a single tool that should be named `Intermediate Answer`.
|
||||
This tool should be able to lookup factual answers to questions. This agent
|
||||
is equivalent to the original [self ask with search paper](https://ofir.io/self-ask.pdf),
|
||||
where a Google search API was provided as the tool.
|
||||
|
||||
### `conversational-react-description`
|
||||
|
||||
This agent is designed to be used in conversational settings.
|
||||
The prompt is designed to make the agent helpful and conversational.
|
||||
It uses the ReAct framework to decide which tool to use, and uses memory to remember the previous conversation interactions.

There are two different ways of doing this - you can either let the agent use the vectorstores as normal tools, or you can set `return_direct=True` to really just use the agent as a router."

"This notebook goes over how to serialize agents. For this notebook, it is important to understand the distinction we draw between `agents` and `tools`. An agent is the LLM powered decision maker that decides which actions to take and in which order. Tools are various instruments (functions) an agent has access to, through which an agent can interact with the outside world. When people generally use agents, they primarily talk about using an agent WITH tools. However, when we talk about serialization of agents, we are talking about the agent by itself. We plan to add support for serializing an agent WITH tools sometime in the future.\n",

||||
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 <./tools.html>`_
|
||||
- Agents: An agent uses an LLMChain to determine which tools to use. For a list of all available agent types, see `here <./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.

# 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.
|
||||
|
||||
Currently, tools can be loaded with the following snippet:
|
||||
|
||||
```python
|
||||
from langchain.agents import load_tools
|
||||
tool_names = [...]
|
||||
tools = load_tools(tool_names)
|
||||
```
|
||||
|
||||
Some tools (e.g. chains, agents) may require a base LLM to use to initialize them.
|
||||
In that case, you can pass in an LLM as well:
|
||||
|
||||
```python
|
||||
from langchain.agents import load_tools
|
||||
tool_names = [...]
|
||||
llm = ...
|
||||
tools = load_tools(tool_names, llm=llm)
|
||||
```
|
||||
|
||||
Below is a list of all supported tools and relevant information:
|
||||
|
||||
- Tool Name: The name the LLM refers to the tool by.
|
||||
- Tool Description: The description of the tool that is passed to the LLM.
|
||||
- Notes: Notes about the tool that are NOT passed to the LLM.
|
||||
- Requires LLM: Whether this tool requires an LLM to be initialized.
|
||||
- (Optional) Extra Parameters: What extra parameters are required to initialize this tool.
|
||||
|
||||
## List of Tools
|
||||
|
||||
**python_repl**
|
||||
|
||||
- Tool Name: Python REPL
|
||||
- Tool Description: A Python shell. Use this to execute python commands. Input should be a valid python command. If you expect output it should be printed out.
|
||||
- Notes: Maintains state.
|
||||
- Requires LLM: No
|
||||
|
||||
**serpapi**
|
||||
|
||||
- Tool Name: Search
|
||||
- Tool Description: A search engine. Useful for when you need to answer questions about current events. Input should be a search query.
|
||||
- Notes: Calls the Serp API and then parses results.
|
||||

"# Moderation\n",
|

"This notebook walks through examples of how to use a moderation chain, and several common ways for doing so. Moderation chains are useful for detecting text that could be hateful, violent, etc. This can be useful to apply on both user input, but also on the output of a Language Model. Some API providers, like OpenAI, [specifically prohibit](https://beta.openai.com/docs/usage-policies/use-case-policy) you, or your end users, from generating some types of harmful content. To comply with this (and to just generally prevent your application from being harmful) you may often want to append a moderation chain to any LLMChains, in order to make sure any output the LLM generates is not harmful.\n",
|
||||
"\n",
|
||||
"If the content passed into the moderation chain is harmful, there is not one best way to handle it, it probably depends on your application. Sometimes you may want to throw an error in the Chain (and have your application handle that). Other times, you may want to return something to the user explaining that the text was harmful. There could even be other ways to handle it! We will cover all these ways in this notebook.\n",
