Simple, transparent pricing

Public prices for AI video and image models. Pay only for what you generate, with one balance shared with the Modelflare API.

Pay per generation

Each image or video is charged from actual model usage. Nothing is billed while you browse, compare or write a prompt.

Priced by specification

Resolution, duration, size and quality set the rate. Choose a specification and the price updates before you generate.

One balance with Modelflare

Funds go into a shared wallet that also pays for direct API calls. No second wallet, no conversion step, and the balance does not expire.

Image & video models

Public prices for every model available in Studio and through the API. Expand a row for billing details.

Language models are priced per million tokens

GPT, Claude, Grok and other language models are billed on Modelflare with separate input and output rates. The full pricing page lists cache, long-context and other conditions.
