Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Useful for first drafts. v0 is the better bet for shipping code.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
