Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for open-source model APIs. The default in this space.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
