UltimateBlend XL API Documentation

This is a new merge that I have just finalised. There were several models that I really liked the results of, but I didn't want to have to keep swapping between them to get the results I was after, so I painstakingly went about merging them. This took many hours of merging and testing different models, in varying amounts, and comparing the output from many prompts until I was pleased with the final images.
