Not just speed, also reliability. IME, Gemini's speed and quality doesn't degrade badly during weekday working hours compared to OAI, and especially Anthropic.

I've had Gemini model API use degrade the most out of OAI/Anthropic/Google (often "over capacity" vs true failures)

Not sure on consumer/product use though

That's interesting to hear. I should have added that I use Gemini through Google AI Studio as my general chat model, which probably explains our wildly different experiences.
