Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
