Models & tools

Pick the right model for the job. Each one has a fixed credit cost per image.

gramatic gives you a curated set of image models plus a handful of editing tools. Costs are fixed per generation and shown here in credits; you’re only charged when a generation succeeds. For current top-up rates see pricing, and for the full machine-readable parameter schemas see the API reference.

Costs can change

Model availability and pricing are part of gramatic and may change over time. The studio always shows the live cost before you generate.
