Best for	Anyone who wants top-tier video quality for less.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Game developers, podcasters needing SFX, video creators needing background music.	Therapy apps, customer service, any voice agent where emotion matters.
Strengths	Very strong motion + physics Often beats Runway on realism Great price	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Detects + mirrors emotional tone EVI (Empathic Voice Interface) feels different Expressive voice output
Weaknesses	UX is rough for English speakers Queue times	Terminal-based — learning curve Can't be used without Claude subscription	Not for full songs with vocals Shorter generation limits	Niche use case Pricing ramps fast
Kai's verdict	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	A-tier in its niche. The only one that actually gets emotion right.
