What Is HiDream O1 Image?
HiDream O1 Image is a unified image model: the same operation can start from text, revise one image or combine several subject references. It supports custom dimensions up to roughly 2K without switching to a separate editing model.

HiDream O1 Image Prompt Examples

HiDream O1 Image Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for HiDream O1 Image, so this page shows no scores. We do not publish numbers we have not measured.
HiDream O1 Image Limitations
- The interface caps references at three for predictable prompts
- The full 50-step model is slower than its distilled variants
- Dense copy still needs proofreading

Frequently Asked Questions
Does editing call a different model?+
No. This integration uses the unified HiDream O1 Image operation and passes references directly.
Why only three references?+
The upstream schema allows multiple images without publishing a numeric limit, so the interface uses a conservative cap.
