Artificial Analysis
Independent evaluations across composite intelligence, hard reasoning, science reasoning, and agentic terminal tasks. Multiple boards live under one publisher.
Tool use
Terminal-Bench 4.0
The current Terminal-Bench version (Aug 2026): 66 long, multi-step shell tasks with an 8-hour agent timeout, run through the Harbor harness.
Why it matters
It tests the loop around a model — planning, commands, file changes, and validation — on tasks that are not yet saturated.
Use it when
You are choosing a model for terminal or coding agents and want an independent, current terminal-task signal.
The limitation
These rows are Artificial Analysis's own runs (the Terminal-Bench component of Intelligence Index v4.3.2). The maintainers' tbench.ai board lists vendor agent harnesses and reports different numbers; do not mix the two, and never compare with 2.x or 3.0 scores.

Comparability
Not comparable with 2.x or 3.0 — new task set
Only three exact public Artificial Analysis headline configurations are retained. These are AA runs, not the separate tbench.ai vendor-harness board. The full AA component data require publisher access. 3 exact matching primary-source observations are ranked in this retained subset. 185 unsupported observations are excluded from ranks, charts and leader claims. Subset ranks are not positions on the complete publisher leaderboard. Exact retained receipts captured 2026-10-01; source/run dates are shown per verified row when known.
