Model overview

gpt-image-1.5 is OpenAI's latest image generation model that improves upon previous versions with better instruction following and closer adherence to user prompts. This model generates high-quality images from text descriptions and can incorporate input images to guide the generation process. Compared to gpt-image-1, this version delivers enhanced prompt understanding and more reliable results that match user intentions.

Model inputs and outputs

The model accepts a variety of parameters to control image generation. Users provide a text prompt describing the desired image and can optionally include reference images to influence the output style and features. The model returns generated images in the requested format and dimensions.

Inputs

Prompt: A text description of the desired image
Aspect ratio: The dimensions of the generated image (1:1, 3:2, or 2:3)
Input fidelity: Controls how much the model matches the style and facial features of input images (low or high)
Input images: Optional reference images to guide generation
Number of images: How many images to generate (1-10)
Quality: The quality level of output (low, medium, high, or auto)
Background: Whether the background is transparent, opaque, or automatic
Output format: File format for the generated images (PNG, JPEG, or WebP)
Output compression: Compression level for the output (0-100%)
Moderation: Content moderation level (auto or low)
