Price list
Image models, priced per picture
Every model that draws, at the price its vendor publishes: per image, per megapixel or per token. One key calls any of them.
Each price includes Antimatter's 10% margin on the upstream's published price. A picture is billed what the upstream reports for it, plus that margin.

A price per token depends on the size and quality asked for: a larger or finer picture takes more image tokens.
“From” is the lowest of several published prices, for the smallest size or the cheapest host. Reference images may cost extra where the vendor charges for them.
