Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for open-source model APIs. The default in this space.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
