Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
