FAQ

About GPT Image 1.5 API

It is OpenAI's GPT Image 1.5 model with the same request fields as GPT Image 1: prompt, optional aspect_ratio, optional quality, and optional image_urls for references.

Both expose the same controls in the playground. Image 1.5 is the newer tier aimed at better detail and adherence when prompts and references are demanding.

You can include up to 16 reference images in one call, each up to 100 MB, matching the GPT Image 1 limits.

Requests are billed through Unifically using the openai/gpt-image-1.5 price key. Check the product pricing table for the current rate.
