As a stealth model, it was priced as $1.25M in / $10M out

Right now, it seems free when you are a Cursor Pro user, but I'd love more clarity on how much it will cost (I can't believe it'll be unlimited usage for subscribers)

A bit late but it's actually not free. You can see it on their models page. It's similarly priced to GPT-5 and Gemini 2.5 Pro.
