Choose LangChain if...

Engineers building production RAG systems, multi-step AI agents, or complex LLM pipelines.

Avoid LangChain if...

Simple single-API-call applications — direct API calls are simpler and faster.

Choose Together AI if...

If you need the absolute frontier (GPT-5, Claude Opus 4.7) — those are first-party only. Stick with Anthropic/OpenAI direct.
