Chronos

A face, forwards or backwards in time

Open a photo and slide towards younger or older, or make a timeline of five ages at once. Chronos learns the face first so every age still looks like the same person, and holds the face's gender while it ages it.

What it looks like

Three timelines at Balanced quality: much younger, younger, as they are, older, much older. Every face is an AI-generated person who doesn't exist. Click to enlarge.

Three faces, each from much younger to much older

Use it

  1. Python 3.9 - 3.12; an NVIDIA GPU (4 GB is enough).
  2. Start run.bat (or run.ps1, run.sh). The first run sets itself up; next to Changeling Tiresias it borrows its models instead of downloading them again.
  3. Open photo, slide Age, press Age, then Save.
