Best forDevelopers experimenting across models. Apps that want fallback logic.Designers, brand teams, anyone needing vector output or tight style control.People who want to hand off tasks entirely — trip planning, research, spreadsheet building.Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths
  • 300+ models from one endpoint
  • Automatic fallbacks between providers
  • No subscription — just pay what you use
  • Exports SVG vectors — rare in AI image gen
  • Strong style control + consistency
  • Brand kit for consistent outputs
  • General-purpose agent — research, book, build, analyze
  • Parallel task execution
  • Web browsing + file creation + coding
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
Weaknesses
  • Slight markup over direct API
  • Some provider features not exposed
  • Less hyped than Midjourney
  • Learning curve for non-designers
  • Still hit-or-miss on complex multi-hour tasks
  • Can burn credits fast
  • Cold starts on less-popular models
  • Pricing gets real at scale
Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier for designers. The only one that takes vectors seriously.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for open-source model APIs. The default in this space.
