Hello!
This update introduces important improvements to stability, performance, and image quality across the app.
The highlight of this release is the new Grain Toggle, which gives users a little more flexibility over the final look of their upscaled images—allowing them to retain natural results or add aesthetic texture to match their creative intent.
Overall, this update enhances both the quality of results and the efficiency of your editing experience.
We appreciate your feedback and look forward to seeing results from your use of Grain!
Thank you!

New Addition: GRAIN
The new Grain Toggle, now available for all models both locally and in the cloud! While our generative models can occasionally introduce results that feel a bit too smooth or artificial, this subtle but powerful control lets users dial grain back into the image to restore texture and realism. Whether you’re matching the feel of a camera sensor, preserving film-like detail, or avoiding overly polished outputs, the Grain Toggle offers a simple way to create more natural-looking results with just a single adjustment.
You can find the Grain toggle beneath the model settings in the right panel.
Use the different sliders to adjust the grain to your liking. Turn the toggle on and off to review the grain.
Let us know if there is more we can do to improve this feature!
