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.
