the upscale i show in the course are not topaz, im not sure which upscaler you are referring to, the tool that aqif made or the ones I show in the course, but I show 2 different upscalers i use in the course. One is a bulk upscaler that is free and uses computer resources and another that is a paid tool that includes ai image editing software along with it. the tool upscale is a automator in midjoureny that automates the upscale process.
