Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier if you already pay Gemini. B-tier standalone.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
