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.
I wanted to start using the Alibaba cloud for a personal project six months ago, couldn't make sense of the pricing and just gave up, so it's not new in my humble experience...
Alibaba Plus: input: $1 to $6 output: $5 to $60
Alibaba OpenSource: input: $1.50 to $4.50 output: $7.50 to $22.50
So it doesn't look that cheap comparing to Kimi k2 or their non coder version (Qwen3 235B A22B 2507).
What's more confusing this "up to" pricing that supposed to can reach $60 for output - with agents it's not that easy to control context.
