Results

One row per model: its best reported result. The rank is the position in this list, by score; the source's own ranking can differ.

Tokscale usage counts accounts that used the model in public Tokscale submissions, Oct 14 – Nov 12, 2026. It is shown next to the score and does not explain it.

Method and matching

How results are run

  • Externally reported results collected by Epoch AI. The reasoning effort is often not reported.

Matching to Tokscale models

  • 50 of 56 results are matched to 40 Tokscale models: 24 by exact id, 26 by normalized name.
  • No match is marked as reviewed by hand yet.
  • 6 results from 6 models are not matched. They stay in the table without a Tokscale link.
  • Reasoning effort, thinking budget and agent are conditions of a result. They never change which model a result belongs to.

Sources and attribution

Each score keeps its own source, unit and run conditions. Tokscale does not combine benchmarks into one score, and a missing score means the model was not evaluated, not that it scored zero.
