Missing image run for Sana-Sprint 1.6B 1024px

Three tasks are archived. The infographic was rejected before generation on November 1, 2026 because the ZeroGPU daily quota was exhausted. No overall score is assigned without the fourth output. Run the missing infographic once when the same official demo is available again, then evaluate the complete cohort together.

Documentation
Test protocol of the images

Both models receive the same archived prompt in exactly one request, and the first result counts. Files are normalized to 1,024 × 1,024 pixels without cropping. Provider resolution, randomness, quality tier and prompt processing can still differ. The images are a practical visual test, not a reconstruction of the arena configuration.
