## Decision facts: langchaingo

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

## Choose when

### Choose Agent-Reach if…

- Agent-Reach is primarily Python; langchaingo is Go.
- Tags unique to Agent-Reach: agent-infrastructure, ai-agent, ai-search, automation.
- Also covers AI Agents.

### Choose langchaingo if…

- langchaingo is primarily Go; Agent-Reach is Python.
- Tags unique to langchaingo: ai, go, golang, langchain.
- - You are working on a project that requires LLM-based capabilities, but prefer to code in Go.

## When NOT to use Agent-Reach

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use langchaingo

- - 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.
