MATILDA-jev Demo

A Gradio demo of Maincode's 26B MATILDA-jev-v1 one-pass decision model: feed a text or JSON state, optionally an image, and a choice, noul, or score question to get calibrated probabilities over your options.

Highlights

  • Runs Maincode/matilda-jev-v1, a 26B one-pass decision model with a 255-option readout.
  • Accepts a text or JSON state, optionally an image, plus a choice, noul, or score question, and returns calibrated probabilities over your options.
  • The maincode_jev_serve/ folder is the Apache-2.0 runtime from the model repo, used unchanged for prompting, batching, readout, and temperature calibration.
  • Example images come from linoyts/repo-to-space-example-inputs, which the card notes is CC0.

Watch out

The card is short: it confirms the Apache-2.0 runtime is reused unchanged, but the demo's own measurements, latency, and input-size limits are not documented here, and image handling is not described beyond the optional input. Example images are CC0 stock from a separate dataset repository.
