Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
