In one sentence

Boilerplate

ModelSpec is an analysis of alternatives for AI models: it decides which models fit a job from your requirements, sourced benchmarks and real cost, and shows its work. ModelSpec at modelspec.dev is not OpenAI's Model Spec, the CNCF ModelPack model-spec, or the Python package named modelspec. Your requirements are Must conditions and your priorities Prefer weights. Ability is estimated from every admitted benchmark, beside cost per task, how sure the evidence is, and the models screened out, with the reason for each. It does not route or proxy requests: use it to decide which models are worth routing to, then let a router choose among them per request.

  • modelspec-mark-transparent.svg: no tile, for dark backgrounds (re-exported 2026-09-25: the delivered file still carried the tile; derivative, so no C2PA manifest)
  • modelspec-lockup-light.svg / -dark.svg: mark + wordmark (text uses Segoe UI; outline before external use)
  • png/: 16, 32, 48 (favicon), 64, 180 (apple-touch), 192, 512 (PWA), 1024

Colors: tile #0B1426 · y-axis #F2C94C (0.9) · x-axis #3FB68B (2.2) · M #FFFFFF (1.5) · dots #5AA9EC r1.9, 1px tile-colored halo

For the social images: The platform UI crops avatars to a circle in some views. Keep the full mark inside the canvas and do not add text to an avatar.
