Stanford's Terminal-Bench-Science: Claude Opus 5 solves only ~30% of research tasks

realsohamparekh · x · 2026-08-28

A Stanford-led community effort released Terminal-Bench-Science (v0.1, 70 tasks), a benchmark evaluating AI agents on research workflows across scientific domains, built by the Terminal-Bench team with domain experts at research institutions worldwide. Claude Opus 5 solves only 30%.

One user broke down its task design philosophy: it explicitly rejects textbook differential equations, generic CSV cleaning, standard undergrad ML exercises, literature summaries, and tasks solvable by looking up one obscure fact (an interesting exclusion). As a 0.1.0 release, its future looks promising.
