Strengths	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Unlimited free tier for solo use Strong summaries + action items Works in Zoom, Meet, Teams	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier

Kai's verdict	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for solo + free. The best free option, hands down.	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier for speed. When latency is the product, start here.
