Defaults to adding one to the patch version. - __Optional__: `--bump-deps` eg `--bump-deps` Will find all packages in the repo which depend on this workspace and checkout a new branch, update the dep version, run yarn install, commit & push to new branch. - __Optional__: `--tag ` eg `--tag beta` Add a tag to the NPM release. -- __Optional__: `--inc ` eg `--inc patch` The semver increment to apply to the version. Can be one of `major`, `minor`, `patch`, `premajor`, `preminor`, `prepatch`, or `prerelease`. Defaults to `patch`. This script automatically bumps the package version, creates a new release branch with the changes, pushes the branch to GitHub, uses `release-it` to automatically release to NPM, and more depending on the flags passed.

Retrieval is useful when you have too much data to pass to the LLM directly. +You can then use a retriever to fetch only the most relevant pieces and pass those in. -const messages = [new HumanMessage({ content: text })]; +In this process, we will look up relevant documents from a Retriever and then pass them into the prompt. +A Retriever can be backed by anything - a SQL table, the internet, etc - but in this instance we will populate a vector store and use that as a retriever. +For more information on vectorstores, see [this documentation](/docs/modules/data_connection/vectorstores). -const llmResult = await llm.predictMessages(messages); -/* - AIMessage { - content: "Feetful of Fun" - } -*/ +First, we need to load the data that we want to index. We'll use [a document loader](/docs/integrations/document_loaders/web_loaders/web_cheerio) that uses the popular +[Cheerio npm package](https://www.npmjs.com/package/cheerio) as a peer dependency to parse data from webpages. Install it as shown below: -const chatModelResult = await chatModel.predictMessages(messages); -/* - AIMessage { - content: "Socks O'Color" - } -*/ +```bash npm2yarn +npm install cheerio ``` -For both these methods, you can also pass in parameters as keyword arguments. For example, you could pass in `temperature: 0` to adjust the temperature that is used from what the object was configured with. Whatever values are passed in during run time will always override what the object was configured with. +Then, use it like this: -## Prompt templates +```ts +import { CheerioWebBaseLoader } from "langchain/document_loaders/web/cheerio"; -Most LLM applications do not pass user input directly into an LLM. Usually they will add the user input to a larger piece of text, called a prompt template, that provides additional context on the specific task at hand. +const loader = new CheerioWebBaseLoader( + "https://docs.smith.langchain.com/overview" +); -In the previous example, the text we passed to the model contained instructions to generate a company name. For our application, it'd be great if the user only had to provide the description of a company/product, without having to worry about giving the model instructions. +const docs = await loader.load(); -PromptTemplates help with exactly this! They bundle up all the logic for going from user input into a fully formatted prompt. This can start off very simple - for example, a prompt to produce the above string would just be: +console.log(docs.length); +console.log(docs[0].pageContent.length); +``` -```typescript -import { PromptTemplate } from "langchain/prompts"; +``` +45772 +``` -const prompt = PromptTemplate.fromTemplate( - "What is a good name for a company that makes {product}?" +Note that the size of the loaded document is large and may exceed the maximum amount of data we can pass in a single model call. +We can split the document into more manageable chunks to get around this limitation and to reduce the amount of distraction +to the model using a [text splitter](/docs/modules/data_connection/document_transformers/): + +``` +import { RecursiveCharacterTextSplitter } from "langchain/text_splitter"; + +const splitter = new RecursiveCharacterTextSplitter(); + +const splitDocs = await splitter.splitDocuments(docs); + +console.log(splitDocs.length); +console.log(splitDocs[0].pageContent.length); +``` + +``` +60 +441 +``` + +Next, we need to index the loaded documents into a vectorstore. +This requires a few components, namely an [embedding model](/docs/modules/data_connection/text_embedding) and a [vectorstore](/docs/modules/data_connection/vectorstores). + +There are many options for both components. Here are some examples for accessing via OpenAI and via local models: + + + + +Make sure you have the `@langchain/openai` package installed and the appropriate environment variables set (these are the same as needed for the model above). + +```ts +import { OpenAIEmbeddings } from "@langchain/openai"; + +const embeddings = new OpenAIEmbeddings(); +``` + + + + +Make sure you have Ollama running (same set up as with the model). + +```ts +import { OllamaEmbeddings } from "@langchain/community/ollama/embeddings"; + +const embeddings = new OllamaEmbeddings({ + model: "mistral", + maxConcurrency: 5, +}); +``` + + + + +Now, we can use this embedding model to ingest documents into a vectorstore. We will use a [simple in-memory demo vectorstore](/docs/integrations/vectorstores/memory) for simplicity's sake: + +**Note:** If you are using local embeddings, this ingestion process may take some time depending on your local hardware. + +```ts +import { MemoryVectorStore } from "langchain/vectorstores/memory"; + +const vectorstore = await MemoryVectorStore.fromDocuments( + splitDocs, + embeddings ); +``` + +The LangChain vectorstore class will automatically prepare each raw document using the embeddings model. + +Now that we have this data indexed in a vectorstore, we will create a retrieval chain. This chain will take an incoming question, look up relevant documents, then pass those documents along with the original question into an LLM and ask it to answer the original question. -const formattedPrompt = await prompt.format({ - product: "colorful socks", +First, let's set up the chain that takes a question and the retrieved documents and generates an answer. + +```ts +import { createStuffDocumentsChain } from "langchain/chains/combine_documents"; +import { ChatPromptTemplate } from "@langchain/core/prompts"; + +const prompt = + ChatPromptTemplate.fromTemplate(`Answer the following question based only on the provided context: + + +{context} + + +Question: {input}`); + +const documentChain = await createStuffDocumentsChain({ + llm: chatModel, + prompt, }); -/* - "What is a good name for a company that makes colorful socks?" -*/ ``` -There are several advantages to using these over raw string formatting. You can "partial" out variables - e.g. you can format only some of the variables at a time. You can compose them together, easily combining different templates into a single prompt. For explanations of these functionalities, see the [section on prompts](/docs/modules/model_io/prompts) for more detail. +If we wanted to, we could run this ourselves by passing in documents directly: -PromptTemplates can also be used to produce a list of messages. In this case, the prompt not only contains information about the content, but also each message (its role, its position in the list, etc). Here, what happens most often is a ChatPromptTemplate is a list of ChatMessageTemplates. Each ChatMessageTemplate contains instructions for how to format that ChatMessage - its role, and then also its content. Let's take a look at this below: +```ts +import { Document } from "@langchain/core/documents"; -```typescript -import { ChatPromptTemplate } from "langchain/prompts"; +await documentChain.invoke({ + input: "what is LangSmith?", + context: [ + new Document({ + pageContent: + "LangSmith is a platform for building production-grade LLM applications.", + }), + ], +}); +``` + +``` + LangSmith is a platform for building production-grade Large Language Model (LLM) applications. +``` + +However, we want the documents to first come from the retriever we just set up. +That way, for a given question we can use the retriever to dynamically select the most relevant documents and pass those in. + +```ts +import { createRetrievalChain } from "langchain/chains/retrieval"; + +const retriever = vectorstore.asRetriever(); + +const retrievalChain = await createRetrievalChain({ + combineDocsChain: documentChain, + retriever, +}); +``` + +We can now invoke this chain. This returns an object - the response from the LLM is in the `answer` key: + +```ts +const result = await retrievalChain.invoke({ + input: "what is LangSmith?", +}); + +console.log(result.answer); +``` + +``` + LangSmith is a tool developed by LangChain that is used for debugging and monitoring LLMs, chains, and agents in order to improve their performance and reliability for use in production. +``` + +:::tip +Check out this public [LangSmith trace](https://smith.langchain.com/public/b4c3e7bd-d850-4cb2-9c44-2e8c2daed7ba/r) showing the steps of the retrieval chain. +::: + +This answer should be much more accurate! + +### Diving Deeper + +We've now successfully set up a basic retrieval chain. We only touched on the basics of retrieval - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/data_connection). + +## Conversation Retrieval Chain + +The chain we've created so far can only answer single questions. One of the main types of LLM applications that people are building are chat bots.

Exact Input/Output Visualization: LangSmith provides a straightforward visualization of the exact inputs and outputs for all LLM calls. This helps you understand the specific inputs provided to the model and the corresponding output generated. -In this getting started guide, we will write our own output parser - one that converts a comma separated list into a list. +2. Editing Prompts: If you encounter a bad output or want to experiment with different inputs, you can edit the prompts directly in LangSmith. By modifying the prompt, you can observe the resulting changes in the output. LangSmith includes a playground feature where you can modify prompts and re-run them multiple times to analyze the impact on the output. -```typescript -import { BaseOutputParser } from "langchain/schema/output_parser"; - -/** - * Parse the output of an LLM call to a comma-separated list. - */ -class CommaSeparatedListOutputParser extends BaseOutputParser { - async parse(text: string): Promise { - return text.split(",").map((item) => item.trim()); - } -} +3. Constructing Datasets: LangSmith simplifies the process of constructing datasets for testing changes in your application. You can quickly edit examples and add them to datasets, expanding your evaluation sets or fine-tuning your model for improved quality or reduced costs. -const parser = new CommaSeparatedListOutputParser(); +4. Monitoring and Troubleshooting: Once your application is ready for production, LangSmith can be used to monitor its performance. You can log all traces, visualize latency and token usage statistics, and troubleshoot specific issues as they arise. LangSmith also allows you to associate feedback programmatically with runs, enabling you to track performance over time and pinpoint underperforming data points. -const result = await parser.parse("hi, bye"); -/* - ['hi', 'bye'] -*/ +In summary, LangSmith helps you test, debug, and monitor your LLM applications, providing tools to visualize inputs/outputs, edit prompts, construct datasets, and monitor performance. ``` -## PromptTemplate + LLM + OutputParser +:::tip +Here's a public [LangSmith trace](https://smith.langchain.com/public/bd2cc487-cdab-4934-b1ee-fceec154992b/r) of the above run! +::: -We can now combine all these into one chain. This chain will take input variables, pass those to a prompt template to create a prompt, pass the prompt to a language model, and then pass the output through an (optional) output parser.

Currently, running the chain over the data points needs to be done client-side. The LangSmith client makes it easy to pull down a dataset and then run a chain over them, logging the results to a new project associated with the dataset. From there, you can review them. We've made it easy to assign feedback to runs and mark them as correct or incorrect directly in the web app, displaying aggregate statistics for each test project.We also make it easier to evaluate these runs.

It includes a name and description that communicate to the model what the tool does and when to use it. +The simpler the input to a tool is, the easier it is for an LLM to be able to use it. +Many agents will only work with tools that have a single string input. +For a list of agent types and which ones work with more complicated inputs, please see [this documentation](/docs/modules/agents/agent_types) + +Importantly, the name, description, and schema (if used) are all used in the prompt. +Therefore, it is really important that they are clear and describe exactly how the tool should be used. You may need to change the default name, description, or schema if the LLM is not understanding how to use the tool. + +## Default Tools + +Let's take a look at how to work with tools. To do this, let's look at a built in tool that takes a simple string input: ```typescript -interface Tool { - call(arg: string): Promise; +import { WikipediaQueryRun } from "@langchain/community/tools/wikipedia_query_run"; - name: string; +const tool = new WikipediaQueryRun({ + topKResults: 1, + maxDocContentLength: 100, +}); - description: string; -} -``` +console.log(tool.name); -## Advanced +/* + wikipedia-api +*/ -To implement your own tool you can subclass the `Tool` class and implement the `_call` method. The `_call` method is called with the input text and should return the output text. The Tool superclass implements the `call` method, which takes care of calling the right CallbackManager methods before and after calling your `_call` method. When an error occurs, the `_call` method should when possible return a string representing an error, rather than throwing an error. This allows the error to be passed to the LLM and the LLM can decide how to handle it. If an error is thrown then execution of the agent will stop. +console.log(tool.description); -```typescript -abstract class Tool { - abstract _call(arg: string): Promise; +/* + A tool for interacting with and fetching data from the Wikipedia API. +*/ + +const res = await tool.invoke("Langchain"); - abstract name: string; +console.log(res); - abstract description: string; -} +/* + Page: LangChain + Summary: LangChain is a framework designed to simplify the creation of applications +*/ ``` + +You can define more complex `StructuredTool`s as well that require object inputs with several different parameters. diff --git a/docs/core_docs/docs/modules/agents/tools/toolkits.mdx b/docs/core_docs/docs/modules/agents/tools/toolkits.mdx new file mode 100644 index 000000000000..f0fdf230629f --- /dev/null +++ b/docs/core_docs/docs/modules/agents/tools/toolkits.mdx @@ -0,0 +1,21 @@ +--- +sidebar_position: 0 +--- + +# Toolkits + +Toolkits are collections of tools that are designed to be used together for specific tasks and have convenient loading methods. +For a complete list of these, visit the section in [Integrations](/docs/integrations/toolkits). + +All Toolkits expose a `getTools()` method which returns a list of tools.

LangChain gives you the building blocks to interface with any language model. Everything in this section is about making it easier to work with models. This largely involves a clear interface for what a model is, helper utils for constructing inputs to models, and helper utils for working with the outputs of models. + +## Models + +There are two main types of models that LangChain integrates with: LLMs and Chat Models. These are defined by their input and output types. + +### LLMs + +LLMs in LangChain refer to pure text completion models. +The APIs they wrap take a string prompt as input and output a string completion. OpenAI's GPT-3 is implemented as an LLM. + +### Chat Models + +Chat models are often backed by LLMs but tuned specifically for having conversations. +Crucially, their provider APIs use a different interface than pure text completion models. Instead of a single string, +they take a list of chat messages as input and they return an AI message as output. See the section below for more details on what exactly a message consists of. GPT-4 and Anthropic's Claude-2 are both implemented as chat models. + +### Considerations + +These two API types have pretty different input and output schemas. This means that best way to interact with them may be quite different. Although LangChain makes it possible to treat them interchangeably, that doesn't mean you **should**. In particular, the prompting strategies for LLMs vs ChatModels may be quite different. This means that you will want to make sure the prompt you are using is designed for the model type you are working with. + +Additionally, not all models are the same. Different models have different prompting strategies that work best for them. For example, Anthropic's models work best with XML while OpenAI's work best with JSON. This means that the prompt you use for one model may not transfer to other ones. LangChain provides a lot of default prompts, however these are not garunteed to work well with the model are you using. Historically speaking, most prompts work well with OpenAI but are not heavily tested on other models. This is something we are working to address, but it is something you should keep in mind. + +## Messages + +ChatModels take a list of messages as input and return a message. There are a few different types of messages. All messages have a `role` and a `content` property. The `role` describes WHO is saying the message. LangChain has different message classes for different roles. The `content` property described the content of the message. This can be a few different things: + +- A string (most models are this way) +- A List of dictionaries (this is used for multi-modal input, where the dictionary contains information about that input type and that input location) + +In addition, messages have an `additional_kwargs` property. This is where additional information about messages can be passed. This is largely used for input parameters that are _provider specific_ and not general. The best known example of this is `function_call` from OpenAI. + +### HumanMessage + +This represents a message from the user. Generally consists only of content. + +### AIMessage + +This represents a message from the model. This may have `additional_kwargs` in it - for example `functional_call` if using OpenAI Function calling. + +### SystemMessage + +This represents a system message. Only some models support this. This tells the model how to behave. This generally only consists of content. + +### FunctionMessage + +This represents the result of a function call. In addition to `role` and `content`, this message has a `name` parameter which conveys the name of the function that was called to produce this result. + +### ToolMessage + +This represents the result of a tool call. This is distinct from a FunctionMessage in order to match OpenAI's `function` and `tool` message types. In addition to `role` and `content`, this message has a `tool_call_id` parameter which conveys the id of the call to the tool that was called to produce this result. + +## Prompts + +The inputs to language models are often called prompts. Oftentimes, the user input from your app is not the direct input to the model. Rather, their input is transformed in some way to product the string or list of messages that does go into the model. The objects that take user input and transform it into the final string or messages are known as "Prompt Templates". LangChain provides several abstractions to make working with prompts easier. + +### PromptValue + +ChatModels and LLMs take different input types. PromptValue is class designed to be interoptable between the two. It exposes a method to be cast to a string (to work with LLMs) and another to be cast to a list of messages (to work with ChatModels). + +### PromptTemplate + +This is an example of a prompt template. This consists of a template string. This string is then formatted with user inputs to produce a final string. + +### MessagePromptTemplate + +This is an example of a prompt template. This consists of a template **message** - meaning a specific role and a PromptTemplate. This PromptTemplate is then formatted with user inputs to produce a final string that becomes the `content` of this message. + +#### HumanMessagePromptTemplate + +This is MessagePromptTemplate that produces a HumanMessage. + +#### AIMessagePromptTemplate + +This is MessagePromptTemplate that produces an AIMessage. + +#### SystemMessagePromptTemplate + +This is MessagePromptTemplate that produces a SystemMessage. + +### MessagesPlaceholder + +Oftentimes inputs to prompts can be a list of messages. This is when you would use a MessagesPlaceholder. These objects are parameterized by a `variable_name` argument. The input with the same value as this `variable_name` value should be a list of messages. + +### ChatPromptTemplate + +This is an example of a prompt template. This consists of a list of MessagePromptTemplates or MessagePlaceholders. These are then formatted with user inputs to produce a final list of messages. + +## Output Parsers + +The output of models are either strings or a message. Oftentimes, the string or messages contains information formatted in a specific format to be used downstream (e.g. a comma separated list, or JSON blob). Output parsers are responsible for taking in the output of a model and transforming it into a more usable form. These generally work on the `content` of the output message, but occasionally work on values in the `additional_kwargs` field. + +### StrOutputParser + +This is a simple output parser that just converts the output of a language model (LLM or ChatModel) into a string. If the model is an LLM (and therefore outputs a string) it just passes that string through. If the output is a ChatModel (and therefore outputs a message) it passes through the `.content` attribute of the message. + +### OpenAI Functions Parsers + +There are a few parsers dedicated to working with OpenAI function calling. They take the output of the `function_call` and `arguments` parameters (which are inside `additional_kwargs`) and work with those, largely ignoring content. + +### Agent Output Parsers + +[Agents](../agents) are systems that use language models to determine what steps to take. The output of a language model therefore needs to be parsed into some schema that can represent what actions (if any) are to be taken. AgentOutputParsers are responsible for taking raw LLM or ChatModel output and converting it to that schema. The logic inside these output parsers can differ depending on the model and prompting strategy being used. diff --git a/docs/core_docs/docs/modules/model_io/index.mdx b/docs/core_docs/docs/modules/model_io/index.mdx index 3b29596c252c..7a8ccc46f3ef 100644 --- a/docs/core_docs/docs/modules/model_io/index.mdx +++ b/docs/core_docs/docs/modules/model_io/index.mdx @@ -7,10 +7,30 @@ sidebar_class_name: hidden # Model I/O -The core element of any language model application is...the model.
