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.
What does your usage look like?
Not used it but from perusing forums, consensus is OpenRouter has terrible/broken caching for Deepseek wildly inflating token use. The cache metrics are visible so you can verify for yourself (apparently, it's what others have done).
DeepInfra's Cache Read is 6.5 times more expensive than DeepSeek.
And in many scenarios, cache hits are 99% of tokens, so the price difference in caching really adds up quickly.
Interesting. My anecdotal experience is that it is.
