I agree with parent. OpenRouter might be cheaper list-price, but i have been using 10$ on DS platform since April/May, still have 2$ left. Using OpenRouter i depleted the same dollar-amount in a 1-2 weeks with same usage pattern. No idea why.

DeepInfra's Cache Read is 6.5 times more expensive than DeepSeek.

Interesting. My anecdotal experience is that it is.
