About

LangChain Go is the Go language implementation of LangChain, aimed at building LLM-based programs through composability. The README shows a minimal program that sends one prompt to an OpenAI model through the llms package, and links the API reference on pkg.go.dev. The maintainers say the project is moving toward more community-led development.

Use cases: model-inference, agent-orchestration
