Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for open-source model APIs. The default in this space.
