Does the price change with image size or prompt length?

No — billing is flat per image, whatever the prompt length or output size.

Can it use a reference image or edit an existing picture?

Not on RouteMux: Image-01 takes text input only here. MiniMax's own API accepts one subject reference image for image-to-image, but that path is not open on RouteMux.

What is MiniMax Image-01

MiniMax Image-01 (model ID image-01) is MiniMax's image generation model, released in February 2025. MiniMax's release notes describe it as text-to-image generation in multiple sizes.

On RouteMux it takes text input only and answers on the OpenAI Images protocol, so /v1/images/generations works the way an OpenAI-compatible client expects. MiniMax's own API also has an image-to-image path, where a single subject reference image keeps the same character across new scenes; that path is not open on RouteMux, so here the model generates and does not edit or take references.

Billing is a flat rate per image: the price of a picture does not change with prompt length or output size, so the budget for a batch is the image count times the rate. Per MiniMax's docs, prompts can run to 1,500 characters, the default aspect ratio is 1:1 at 1024×1024, and the eight listed ratios run from 16:9 at 1280×720 to 21:9 at 1344×576.
