Auto-Rubric Evaluator

Describe any task and the system auto-builds a weighted rubric, runs two models, and grades each response against every criterion — visualized as an animated head-to-head score matrix.

How it works

  1. Rubric: a grader model designs 3 weighted criteria for your task.
  2. Generate: two models (gpt-5.4, grok-4.3) each attempt the task.
  3. Grade: each response is scored 1–5 per criterion; weighted totals decide the winner.
  4. Scores render as animated A-vs-B bars per criterion.
