Tagline	Anthropic's flagship — best reasoning + longest useful context.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Open-source VS Code agent. Reads + writes + runs.	Kuaishou's video model. The surprise standout.
Category	Chatbots	Coding	Coding	Video
Pricing	Free + $20/mo Pro + team/enterprise	Part of Claude Pro/Max/Team plans	Free (open source) + your API costs	Credit-based, free trial
Best for	Long writing, code, careful thinking, documents over 50 pages.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	VS Code users who want agentic coding without changing IDEs.	Anyone who wants top-tier video quality for less.
Strengths	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Free extension for VS Code Plan + Act modes Model-agnostic (Claude, GPT, local) Sees terminal output and iterates	Very strong motion + physics Often beats Runway on realism Great price
Weaknesses	Image generation is weak No native web search on all tiers	Terminal-based — learning curve Can't be used without Claude subscription	Can burn tokens fast if not watched Less polished than Cursor	UX is rough for English speakers Queue times
Kai's verdict	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. Best free agentic option in VS Code. Use with Claude for best results.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
