What it does

  • Run a prompt through N models. Same prompt, identical parameters, outputs collected side by side.
  • Compare. Line-level diff between any two model outputs.
  • Score. Auto-scorer (length, latency, reference match) + manual user ratings (1-5).
  • Benchmark suites. Save a named set of prompts + models, re-run after changes, get a regression report.
  • Panel. Settings page listing recent runs with drill-down to comparison view.

dsh-model-arena list                              # list recent runs
dsh-model-arena compare <run> <modelA> <modelB>   # diff two models in a run
