|---|---|---|---|
| Prompt | string | Text prompt describing the image to generate. Maximum 20,000 characters. | A girl doing livestream makeup tutorials while tiny workers inside her mirror physically repaint the reflection in real time, miniature ladders, paint buckets, glowing vanity lights, cluttered modern bedroom aesthetic, insanely detailed reflections, playful surreal realism, highly creative composition, luxury commercial quality. |

highDeveloper documentation
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.
Frequently asked
Be specific about the subject, style, lighting, background, and mood. More detail generally produces better results. Prompts up to 20,000 characters are supported.
`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.
Each request generates one image. Submit multiple requests to generate variations.
The model supports a wide range of styles including photorealistic, illustration, concept art, product photography, and more.
