ORAgentBench - Medium Quality: leaderboard

ORAgentBench (2026) tests LLM agents on 107 human-reviewed operations research tasks solved end to end, from multi-file operational data to a validated decision, with hidden validators for feasibility and objective quality; the agents run in the Claude Code or Codex harness. This board is the mean normalized objective quality (0-100, 50 at the verified reference solution, 0 when infeasible) on the 41 medium tasks; higher is better.

Metric: Mean normalized objective quality (0-100) on the 41 medium tasks, zero for infeasible submissions and 0.5 at the verified reference solution; end-to-end operations research tasks packaged with multi-file operational data, configuration and a submission schema; the agent writes and runs solver code in an isolated Harbor environment (45-minute interaction budget, 5-minute solve limit) and hidden validators score schema and hard-constraint feasibility and normalized objective quality; printed 0-1 and x100 here; higher is better.
