Pros
  • + Clean Pydantic integration
  • + Automatic validation
  • + Retry logic built-in
  • + Multi-provider support
  • + Well-documented
  • + Fastest inference available (500-1000 tok/s)
  • + Free tier with generous limits (250K+ tokens/min)
  • + OpenAI-compatible API — swap one line of code
