Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
