Summary

The hires fix on the Images page used a latent upscale at denoise 0.7 whenever its fields were left empty. On a model made for 512-pixel images (such as SD-Turbo) that regenerates the picture at twice its size, so the result repeats structure and no longer matches the same seed without hires.

Every hires field a request leaves out now takes the selected model's suggestion when the job runs: the Lanczos upscaler, the job's steps, denoise 0.35, and scale 2 for models whose native size is at most 640 pixels (1.5 for larger ones). A latent upscaler chosen without a denoise gets 0.55. A model with no known family gets Lanczos, 2 and 0.35. Values the request sets are used as given.

• GET /api/imagine/native-models returns the suggestion in preview.hires.
• The Images page shows it as the upscaler's first option and as the scale and denoise placeholders, and sends only the fields the user filled. A typed value is never replaced when the model changes; a new "Use suggested values" button fills the fields with the suggestion.
• Latent upscalers stay selectable; the sidecar records the values a job used.

How to verify

Pick SD-Turbo, generate one image with a fixed seed, then tick Hires fix with every hires field empty and generate again with the same seed: the second image is the same picture at 1024 pixels.
