Часто задаваемые вопросы
Почему LangChain критикуют?
Over-abstraction (десятки classes для simple chain), fast-changing API (breaking changes every few months), heavy dependencies. Для quick prototype — fine, для production — часто rewrite с simpler.
LlamaIndex vs LangChain?
LlamaIndex: RAG-focused, cleaner для data ingestion/querying. LangChain: более general-purpose (agents, tools, memory).
Vercel AI SDK — что даёт?
Simplest JS framework для LLM. useChat, useCompletion React hooks. Streaming out-of-box. Для Next.js apps — best choice.
Как monitor LLM quality в production?
LangSmith ($39/user), LangFuse (open source), Braintrust. + <a href="/check">Enterno</a> для endpoint uptime.
