LangChain Go

A Go version of LangChain for building programs that use AI language models.

New this week

What it does

LangChain is a popular toolkit for building apps on top of AI language models. LangChain Go brings the same ideas to the Go programming language.

Programmers can use it to send prompts to models such as OpenAI's, Google's Gemini or local Ollama models, and combine steps into larger apps like chatbots.

The README links to examples and articles, and the project invites more community maintainers.
