How to Use GPT Image 2 Text to Image

Write your prompt: Describe the image you want in detail. You can include style, lighting, subject, background, and mood. Up to 20,000 characters are supported.
Pick a quality: Choose low or medium for fast, lower-cost drafts, or high for the highest fidelity output. high is the default.
Pick aspect ratio and resolution: Select an aspect ratio (e.g. 1:1, 16:9, 9:16) and a resolution (1K, 2K, or 4K). Note that 1:1 cannot be rendered at 4K, and auto aspect ratio is locked to 1K.
Submit the request: Click Generate. The model processes your prompt and returns the generated image.
Review and iterate: If the result needs adjustment, refine your prompt with more specific instructions and regenerate.

Common Questions

Frequently asked

What should I include in my prompt?

Be specific about the subject, style, lighting, background, and mood. More detail generally produces better results. Prompts up to 20,000 characters are supported.

What does the quality setting do?

`low` and `medium` are faster and cheaper and are well suited to drafts and bulk generation. `high` runs the full-fidelity model and is best for finals. Pricing scales with both quality and resolution.

Can I generate multiple images at once?

Each request generates one image. Submit multiple requests to generate variations.

What image styles are supported?

The model supports a wide range of styles including photorealistic, illustration, concept art, product photography, and more.
