| # SAM — Face Aging (A.I.M.I Mirror) | |
| Mirror of the **SAM (Style-based Age Manipulation)** pretrained checkpoint by Yuval Alaluf et al. (ICCV 2021), re-hosted here for stable URLs inside the A.I.M.I desktop product. Contents are unmodified — the weights in `sam_ffhq_aging.pt` are byte-identical to the official Google Drive download referenced from [github.com/yuval-alaluf/SAM](https://github.com/yuval-alaluf/SAM). | |
| Used by A.I.M.I's image-editor face-aging feature: shift the apparent age of every detected face in a photo by -50 to +50 years while keeping identity and background intact. | |
| ## Files | |
| | File | Size | Purpose | | |
