Original: Comparing AI Agents Python Library Options for Production

Short summary

A practical comparison of three Python libraries for building production AI agents: LangChain for granular control, CrewAI for multi-agent orchestration, and LlamaIndex for data-centric retrieval. Includes installation commands, code snippets for each library, and a shared weather-lookup agent example. Notes version-mismatch gotchas and recommends pinning dependencies.

  • •LangChain best for granular prompt/memory/tool control
  • •CrewAI ideal for multi-agent task decomposition and role assignment
  • •LlamaIndex excels at document retrieval and natural-language querying over vector stores

Generated with AI, which can make mistakes.
