About this project

LangChain Go is the Go-language implementation of LangChain, intended for building applications that combine large language models through composable components. The repository provides a documentation site, package API reference, and usage examples. One example creates an OpenAI model, submits a single prompt asking for a company name, handles errors, and prints the generated completion. The README also links to articles covering Gemini, Ollama, and Go-based ChatGPT-style applications. Developers can seek support, discuss contributions, and join the project's community through Discord.
