Recommendations for generation:
CFG Scale: 3
For portraits, it’s better to use CFG Scale: 2-3, you can increase it to 4 for more colorful arts, for graphics you can use 3-5.
Main formats: 1024x1024, 832x1216, 1216x832
The model works best with the DPM++ 3M SDE Exponential sampler.
Do not use any Lora, embeddings, aditailers, and other additions. All of this was created on old models and will only interfere with generation on the Haveall SDXL model. You can only use new Lora, which will be trained on Haveall SDXL and only them.
SHOWCASE HAVEALL MODEL -> https://haveall.net/ is featured on the model's website. The site shows several hundred examples with images and complete prompts for generation. In the gallery, you can view pictures and prompts. The pictures on the site already have built-in prompts, so you can drag any picture into the PNG INFO tab and get a ready prompt in Automatic or in Forge.
For work, I recommend Forge - when installing by default, upscalers will be downloaded and the speed of work is more optimized. I recommend DAT-4 upscaler for high-res fixes (which is built-in by default in Forge).
