  • Building directly on one vendor can create lock-in
  • No flat free plan; trial credits are limited and not guaranteed
  • Rate limits and some features gated by usage tier

  • Largest frontier models need the paid cloud
  • No built-in team collaboration features
  • Quality depends on chosen model and quantization
  • Local setup still requires adequate RAM and GPU
