Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
