Weaknesses	Cold starts on less-popular models Pricing gets real at scale	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	UX is rough for English speakers Queue times	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate
Kai's verdict	S-tier for open-source model APIs. The default in this space.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	B-tier. Still early. Manus is more flexible for less money.
