Kai's verdictS-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.A-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
