Decision brief

LangChainGo simplifies the integration of Large Language Models into Go projects through easy-to-use APIs and composability.

Good fit when

- You are working on a project that requires LLM-based capabilities, but prefer to code in Go.
- Your team is already proficient in Go and you want to incorporate state-of-the-art language models without switching languages or frameworks.

Avoid when

- If your project strictly adheres to another programming language where other implementations of LangChain are available.
- When your application requires heavy customization at the framework level that might not be directly supported within LangChainGo’s current implementation.
