I created a workflow leveraging Ollama to generate a prompt and then share that prompt with the Process Node and a SDXL image generation which sends the image to the "controlnet_image" input. Setting the Controlnet_weight = 1.0 it is pretty close to the original image with amazing details and upscaling. The initial image is 1344x768 and is upscaled to 3840x2304 which allows me to make the images a wallpaper. Works very well. Falling in love with this.
Added the nodes for this on Thursday and have been very impressed. I'm finding the backgrounds have extra detail and pop to them and it's nice not to have to upscale.
both are non-commercial only. So I am more interested to in best alternatives to these. Anyway for research purpose it would be interesting to compare both.
