Found out this on simonw blog [0]: "his is the first model I've seen that sets different prices for four different sizes of input" [1]

It seems now a every expensive model to run with alibaba as provider. You only get this low price for input <32k. For input <256k both gemini 2.5 pro and o3 is cheaper.
