Why people look for alternatives to Langchain In Action
The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.
- Examples use deprecated LLMChain; LangChain 0.3.0 removes it entirely
- Model names like text-davinci-003 already retired, breaking example code
- Open GitHub issue: Qdrant.from_documents fails with connection errors in RAG lesson
- No pinned requirements.txt — latest libraries often break the demos
