Pricing	Included with ChatGPT Plus/Pro	Free + $12/mo Pro + enterprise	Part of Claude Pro/Max/Team plans	Credit-based, free trial
Best for	ChatGPT subscribers experimenting with cinematic shots.	Game developers, podcasters needing SFX, video creators needing background music.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Anyone who wants top-tier video quality for less.
Strengths	Up to 20-sec clips at 1080p Strong physics + scene composition Storyboard feature for longer narratives Remix existing videos	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Very strong motion + physics Often beats Runway on realism Great price
Weaknesses	Stricter content policy than competitors Hit-or-miss on complex motion Text-in-video still struggles	Not for full songs with vocals Shorter generation limits	Terminal-based — learning curve Can't be used without Claude subscription	UX is rough for English speakers Queue times
Kai's verdict	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
