Steps
Fifty is the full-model default; reduce it for drafts before increasing resolution.
Guidance
Five is the documented starting point for prompt adherence.
The panel above shows only the parameters HiDream I1 Full actually supports. Switch versions and unsupported controls disappear rather than sitting there doing nothing.

HiDream I1 Full 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 I1 Full, so this page shows no scores. We do not publish numbers we have not measured.
HiDream I1 Full Limitations
- Slower than distilled models
- Text-to-image only on this page
- 2K output costs four times the pixels of 1K
