Let’s briefly overview picture high quality and related GPU prices
As a lot of you in all probability already heard, Midjourney dropped a brand new function that allows you to upscale Midjourney-generated photos by 2x or 4x. After you select a picture from the grid of 4 photos by clicking considered one of U1/U2/U3/U4, you’ll see two new buttons underneath the picture: “Upscale (2x)” and “Upscale (4x)”. Click considered one of them to extend the decision of your picture by 2 or 4 occasions, respectively.
A number of issues to know earlier than utilizing this upscaler:
- Upscaling picture will value you numerous GPU minutes with 4x upscaler costing roughly 3x extra GPU minutes than the 2x upscaler. Later on this submit, I’ll present the precise numbers primarily based by myself experiments.
- You might use an upscaler in your earlier generated photos by getting into the command
/presentjob_id. - A blurry low-resolution picture won’t be ‘unblurred’ by upscale.
Now let’s run an experiment.
To take a look at a brand new upscaler, I’ve chosen a picture that has numerous small particulars in order that we will higher see the distinction between the preliminary and upscaled photos.

The picture seems to be nice, however zooming in reveals that the jewellery lacks element and sharpness as a result of low decision. Let’s see how the brand new upscaler handles this problem.
I upscaled the picture with each “Upscale (2x)” and “Upscale (4x)”, zoomed in on the identical part of the necklace, and positioned the ensuing photos side-by-side for simpler comparability.
The outcomes are a bit shocking. The 2x upscaler did a terrific job, including particulars and making the necklace look sharper, much less pixelated, and extra practical. But the 4x…
