Tagline	The fastest AI inference in the world. Crazy low latency.	Terminal-based AI pair programmer. Git-aware, model-flexible.
Category	Dev Platform	Coding
Pricing	Free tier + pay-as-you-go API	Free (open source) + whatever API you use
Best for	Developers who need sub-100ms LLM responses.	Developers who want open-source tooling with full control.
Strengths	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier	Works in any terminal Auto-commits changes with meaningful messages Works with any model (Claude, GPT, local) Minimal learning curve
Weaknesses	Open-weight models only (no Claude/GPT) Less flexibility on custom configs	Terminal-only Less agentic than Claude Code Setup on Windows is fiddly
