To log traces and run evaluations with LangSmith, you will need to create an API key to authenticate your requests. Currently, an API key is scoped to a workspace, so you will need to create an API key for each workspace you want to use.
There are two primary ways to interface LLMs with external APIs: Functions: For example, OpenAI functions is one popular means of doing this. LLM-generated interface: Use an LLM with access to API documentation to create an interface.
In this quickstart we'll show you how to: Get setup with LangChain, LangSmith and LangServe. Use the most basic and common components of LangChain: prompt templates, models, and output parsers. Use LangChain Expression Language, the protocol that LangChain is built on and which facilitates component chaining.

Apr 11, 2024 · When building with LangChain, all steps will automatically be traced in LangSmith. To set up LangSmith we just need set the following environment variables: export LANGCHAIN_TRACING_V2="true" export LANGCHAIN_API_KEY="<your-api-key>" Define tools. We first need to create the tools we want to use.
Use of LangChain is not necessary - LangSmith works on its own! 1. Install LangSmith. Python. TypeScript. pip install -U langsmith. 2. Create an API key. To create an API key head to the Settings page. Then click Create API Key. 3. Set up your environment. Shell. export LANGCHAIN_TRACING_V2=true. export LANGCHAIN_API_KEY=<your-api-key>
Apr 22, 2024 · To use LangChain effectively, you must set up your development environment with the necessary API keys and configurations. Many LLM providers require authentication to access their APIs. For instance, if you're using OpenAI's models, you'll need to obtain an API key from the OpenAI website and set it as an environment variable:
