Jawline

Does the jaw draw one clean, defined line from ear to chin?

ImageFacejawlineVersion 1

Scores the lower third of a face: how sharply the jaw is defined, how cleanly it separates from the neck, and how well the chin projects. A beard or camera angle counts only for what it lets the model see.

What it looks for

A visible jaw edge running from ear to chin
A defined angle at the back of the jaw
Forward chin projection that balances the face
A clean break between the jaw and the neck

Input

Send one image as a base64 data URL in image: PNG, JPEG, or WebP, at most 3 MiB (3,145,728 bytes) decoded. Text is optional context. A request with an image costs 10 units however many image formulas it names, so batch this one with others such as Canthal Tilt and Hunter Eyes, up to 8 per request.

The call returns noul, the probability from 0 to 1 that the answer is yes, and mogs, the verdict. The pass/fail boundary is set on the server and never returned. Use mogs as the decision and noul to rank.

POST /api/v1/mog

# Build the body in a file: a base64 image is too long for a shell argument.
# For a PNG or WebP file, change image/jpeg to image/png or image/webp.
{
  printf '{"formula":"jawline","image":"data:image/jpeg;base64,'
  base64 < photo.jpg | tr -d '\n'
  printf '"}'
} > body.json

# With the mogger skill installed, ask in plain words, for example:
#   Does ./photo.jpg mog on jawline?
# The skill base64-encodes the file in the shell, so the image
# never enters the model context, and runs:
score_image ./photo.jpg jawline | jq '.results'
