Tagline	The pro's AI video tool. Gen-4 is the current bar.	VS Code fork that made AI coding actually work.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Open weights + strong photorealism. The open-source answer.
Category	Video	Coding	Coding	Image
Pricing	Free + $15-$95/mo	Free + $20/mo Pro + $40/mo Business	Part of Claude Pro/Max/Team plans	API + open weights (Schnell is Apache 2.0)
Best for	Marketing video, pitch decks, b-roll, creative shorts.	Developers. Non-developers who want to ship working code.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Developers + power users who want control and privacy.
Strengths	Most mature video workflow Character consistency via Act-One Gen-4 quality is production-grade	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Runs locally on a beefy GPU Very photoreal Best open-weight model
Weaknesses	Expensive at scale Still needs post-editing	Can feel overwhelming for non-coders Expensive at scale	Terminal-based — learning curve Can't be used without Claude subscription	Harder to use than hosted tools Needs infra
Kai's verdict	S-tier. Market leader with reason. Start here for serious video.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. S-tier if you self-host. The reason open-source image gen matters.
