Best for	Engineering teams offloading tickets. Ops/platform work.	Developers. Non-developers who want to ship working code.	Students, researchers, anyone with a stack of PDFs or a topic to learn.	Photographers animating stills, cinematic b-roll.
Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	Best image-to-video in the category Great camera motion control Ray 2 model produces striking shots
Weaknesses	Expensive Best for well-scoped tasks Not for solo hobbyists	Can feel overwhelming for non-coders Expensive at scale	Google-only Can be slow on large corpora	Prompt fidelity below Runway Queue times on free tier
Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
