Weaknesses	Cold starts on less-popular models Pricing gets real at scale	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Bot-joining model Team features gated	Can burn tokens fast if not watched Less polished than Cursor
Kai's verdict	S-tier for open-source model APIs. The default in this space.	B-tier. Still early. Manus is more flexible for less money.	S-tier for solo + free. The best free option, hands down.	A-tier. Best free agentic option in VS Code. Use with Claude for best results.
