TaglineThe fastest AI inference in the world. Crazy low latency.One API, every model. Pay-as-you-go, no subscriptions.Anthropic's CLI agent. Opus-powered, operates on your repo directly.Vector + raster AI for designers. Actually controls the output.

Best forDevelopers who need sub-100ms LLM responses.Developers experimenting across models. Apps that want fallback logic.Developers who want an agent, not autocomplete. Large refactors, tests, docs.Designers, brand teams, anyone needing vector output or tight style control.
Strengths
  • 500+ tokens/sec on Llama/Mixtral — feels instant
  • Custom LPU hardware
  • Great free tier
  • 300+ models from one endpoint
  • Automatic fallbacks between providers
  • No subscription — just pay what you use
  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • Exports SVG vectors — rare in AI image gen
  • Strong style control + consistency
  • Brand kit for consistent outputs
Weaknesses
  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs
  • Slight markup over direct API
  • Some provider features not exposed
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • Less hyped than Midjourney
  • Learning curve for non-designers
Kai's verdictS-tier for speed. When latency is the product, start here.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for designers. The only one that takes vectors seriously.
