Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
