Sana Sprint 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 Sana Sprint, so this page shows no scores. We do not publish numbers we have not measured.
Sana Sprint Limitations
- Text-to-image only
- Fine detail trails larger final-render models
- 4K should be reserved for prompts already proven at 1K

Frequently Asked Questions
Is Sana Sprint really a one-step model?+
The research model is built around one/few-step generation; this endpoint defaults to two and allows up to twenty.
Why does 4K cost two credits?+
Provider billing follows output megapixels, so the 4K tier needs a separate margin-safe credit level.
