Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier inside Photoshop (Generative Fill). B-tier standalone.
