Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for search. I use it before Google now.
