AI EVALUATION, IN CONTEXT.BY EQUALITY MACHINE

Model reports

Terminal-Bench

Environment image, timeout and permitted commands change results independently of the model. Version and harness both matter: 2.0 and 2.1 are different instruments, and cards report Terminus, Claude Code and Codex harness numbers for the same version. Frontier-Bench is this series' next version rather than a separate benchmark: frontierbench.ai now bills it as "Terminal-Bench 3.0 (formerly Frontier-Bench)", built by the makers of Harbor and Terminal-Bench, so its mentions are counted here. Merging it did not raise this count: all three cards that named Frontier-Bench (Claude Opus 5, Claude Fable 5 and Mythos 5, Kimi K3) also report Terminal-Bench in the same document, and the counting unit is the document, so each still adds one. Being a new version, its task set is not comparable to a 2.x number. Not to be confused with Cognition's FrontierCode, a separate instrument recorded separately despite the shared prefix.
