Langchaingo is the Go language port of LangChain, providing composable building blocks for writing LLM-powered applications in Go. It offers integrations with providers like OpenAI, Gemini, and Ollama for generation, chains, agents, and retrieval workflows.

Use cases

• build llm apps in go
• create a chatgpt clone in golang
• call openai from go
• use ollama with go
• build rag pipelines in go
• write llm agents in go
• use gemini models from go

When to choose

• you are building LLM-based applications in Go and want composable abstractions
• you need multi-provider LLM support (OpenAI, Gemini, Ollama) behind one API
• you want a LangChain-style ecosystem (chains, agents, embeddings) natively in Go

When to avoid

• you are working in Python or JavaScript where the original LangChain has a larger ecosystem
• you need only a single provider's SDK with no abstraction layer
• you need cutting-edge LangChain features that may lag behind the Python version
