Image generation: APIs, tasks and billing

Image APIs

• Supports both OpenAI Images and Gemini request formats

• Image and text requests use the same API keys and routing settings

Task processing

• Long-running jobs support queueing and polling

• Busy upstreams return Retry-After so clients can schedule retries

Billing

• Pricing is based on image count and dimensions

• An estimate is reserved on submission; final usage is settled on completion and the remainder is released

• Reasoning text produced before the image is included in usage
