TLDRIn this video, Rodney from Kleebz Tech compares the Juggernaut XL V8 and V9 checkpoints, addressing the common question of which version is superior. He explains that a higher version number doesn't necessarily mean better performance, as different checkpoints may yield varying results with the same prompts. Rodney notes that V9 was trained with the Run Diffusion photo model, potentially offering better results with photographic images. Through a series of comparisons using identical prompts, he observes that while V9 often provides more detailed outputs, V8 performs almost as well, especially when using Fooocus V2. Rodney concludes that for simple prompts, V9 tends to give better results, but for more detailed prompts, the difference is less noticeable. He suggests that users could benefit from using both checkpoints depending on the task. The video also teases an upcoming complete reboot of the Juggernaut model.
