Strengths	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy	First drafts with Make Designs Rename/rearrange layers automatically Natural language asset search	Clone your face + voice in 2 minutes Instant translation into 40+ languages with lip sync Avatars look less uncanny than competitors
Weaknesses	Google-only Can be slow on large corpora	Cold starts on less-popular models Pricing gets real at scale	Features vary by plan + region Still rolling out	Pricey for serious volume Long shots still feel off Ethics — easy to misuse
Kai's verdict	S-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 multilingual video. If you sell courses or speak at events, this is a cheat code.
