Magnific.ai (https://magnific.ai https://magnific.ai) is a paid tool that works well, but it is expensive. However, this weekend someone released an open-source version which has a similar output. (https://replicate.com/philipp1337x/clarity-upscaler https://replicate.com/philipp1337x/clarity-upscaler) I'd recommend trying it. It takes a few tries to get the correct input parameters, and I've noticed anything approaching 4× scale tends to add unwanted hallucinations. For example, I had a picture of a bear I made with Midjourney. At a scale of 2×, it looked great. At a scale of 4×, it adds bear faces into the fur. It also tends to turn human faces into completely different people if they start too small. When it works, though, it really works. The detail it adds can be incredibly realistic. Example bear images: 1. The original from Midjourney: https://i.imgur.com/HNlofCw.jpeg https://i.imgur.com/HNlofCw.jpeg 2.

Upscaled 4×: https://i.imgur.com/Et9Gfgj.jpeg https://i.imgur.com/Et9Gfgj.jpeg ---------- The same person also released a lower-level version with more parameters to tinker with.
