Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Long writing, code, careful thinking, documents over 50 pages.	Grad students, researchers, anyone doing literature reviews.	Anyone who wants top-tier video quality for less.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing	Searches 125M+ papers Extracts + synthesizes findings across papers Systematic review workflow	Very strong motion + physics Often beats Runway on realism Great price
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Image generation is weak No native web search on all tiers	Academic-only Can hallucinate citations — verify everything	UX is rough for English speakers Queue times
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier for academic research. Nothing else comes close for systematic reviews.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
