Why ModelPlan

Choose an entry point: Mac App, plugins or Skill.

Most leaderboards compare every model at its top setting. But inside one model, going from Low to Max often costs several times more and takes several times longer, for a few points of ability. What you actually run is a model at an effort.

  • ★ Recommended effort. Every model gets its best-value effort, and you see exactly what one more step up buys (+4.8 ability) and costs (×1.37).
  • A leaderboard at that effort. Models are ranked at their own ★ effort, the setup you would really use, with cost per reference…
