Pros
  • Official, well-tested abstractions
  • Same primitives as Claude Code
  • Strong tool-use ergonomics
  • TypeScript + Python SDKs
  • OpenAI-compatible endpoint, so most SDKs and agent harnesses drop in unchanged
  • Per-tier fallbacks keep agents running through provider outages and rate limits
  • Auto-fix silently corrects deprecated model IDs and bad parameters
  • Self-hostable via Docker with support for local runtimes (Ollama, LM Studio, Llama.cpp)
  • BYOK plus subscription routing lets you actually use the ChatGPT/Claude plans you already pay for
Cons
  • Claude-only
  • Newer than LangGraph/CrewAI
  • Adds a network hop and another moving piece to debug when calls fail
  • Managed cloud is still early access; production users are mostly on self-host
  • Routing rules and budgets only help if you actually configure them thoughtfully
