According to the official technical report, version 2.5 mainly improves in three aspects:
Enhanced color and contrast. This model can generate images with richer colors and stronger contrast.
Improved generation capabilities at various image scales. Considered the generation needs in different devices and scenarios during training, using datasets containing images of different scales.
Improved detail-oriented enhancements. By better aligning with human preferences, it can generate images with richer details and more in line with human eye expectations.
You can download the model on HuggingFace (link at the end of the article) and configure it for use with A1111 (or Autumn installation package) and comfyUI.
If you are a novice user or do not want to spend effort configuring the environment, you can directly use the online tools provided by Playground.
