Community-submitted runs on the 46-task Long-Horizon Terminal-Bench suite, ranked by mean reward. The seed entries are our Terminus-2 baselines — the same runs analyzed in the report. LHTB is open: bring your own model or your own agent, run the same 46 tasks under the same 90-minute budget, and submit your run. We replay the submitted trajectories against the hidden verifiers and reproduce the score before it lands on the board — the same anti-cheat that grades our own runs. A verified badge means we reproduced it.
Submit a run
Two ways in — evaluate a model on the reference harness, or bring a custom agent.
Evaluate a model · reference harness
harbor run -d long-horizon-terminal-bench \ -a terminus-2 -m "your-provider/your-model" -k 1
Bring your own agent
harbor run -d long-horizon-terminal-bench \ --agent-import-path "path.to.agent:YourAgent" -k 1
Submissions may not modify the 90-minute per-task budget, the container resources, or
the hidden verifiers. One attempt per task (-k 1), errors score 0.
