Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for open-source model APIs. The default in this space.S-tier infrastructure. The one platform every AI dev eventually uses.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
