Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OpenRouter

  • No free tier; all usage incurs cost
  • Pricing varies by model; specific rates not published on main site without account access
  • Adds latency through additional routing layer compared to direct provider APIs
  • Dependent on upstream provider uptime and API compatibility

Ray

  • Windows support is beta and multi node Ray clusters are untested on Windows
  • Windows lacks copy on write forking, which raises memory requirements, and Ray code assumes UNIX filenames
  • Multi node clusters are untested on Apple Silicon Macs
  • The Java API is experimental and community supported only, and requires matching Java and Python versions
  • Python 3.13 support is beta
