Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier in its niche. The only one that actually gets emotion right.S-tier for open-source model APIs. The default in this space.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
