SMFANet+ — Image Upscaler AI Model
SMFANet+ upscales images 2×, 3× or 4× and is by a wide margin the fastest option here — under 0.5M parameters, so a 512px image lands in about 0.1s. The right pick above 2K, where heavier upscalers stall.
What it does
SMFANet+ upscales an image 2x, 3x or 4x, and it is by a wide margin the fastest upscaler here: under half a million parameters, and a 512px image lands in about a tenth of a second.
That speed is the reason to reach for it. Above 2K, where the heavier upscalers stall, this one keeps going. The plus is the stronger sibling of the base SMFANet, tuned for quality while staying in the lightweight class.
When to use it
- Upscaling a large batch without the queue backing up behind it
- Interactive work, where a few seconds of waiting is too many
- Sources above 2K, where the heavier upscalers start to stall
- Thumbnails, chat images, old web images and screenshots
- Frames pulled out of a video, fast enough to be worth doing

Parameters

Upscale ratio (2/3/4)
How many times to enlarge the image on each dimension. 2 (default) is fastest. 3 is intermediate. 4 produces the largest output but takes longest and amplifies any low-frequency artifacts.
