Fixed task set
The same Selected_1000 task IDs and dataset revision are used for every group. Each score is successes ÷ 1,000; failed or unknown tasks stay in the denominator.

Single-pass Agent
One code-generation call, followed by execution. No iterative agent loop.
DeepAgents
DeepAgents plans, uses tools and revises code. Up to 6 model calls, plus final execution.
DeepSeek Harness · separate run
Official DSH SDK, requested v4-pro API alias. A fixed technical recovery selection; underlying model weights are unverified.
01 / RESULTS
Agent & Harness leaderboard
Locally scored, archived results. Official scorer parity is not yet verified. Different budgets and run protocols mean the lift is descriptive, not an equal-cost comparison.

No matching models.
Every score uses all 1,000 tasks. Unknown and invalid outcomes earn no successes.
02 / HOW TO READ THIS
A comparison you can inspect.
Two scoring profiles
Full replication is the local paper metric. The four HF-style metrics reproduce the published descriptions locally; they are not yet verified against the official scorer.
Read lift with the budgets
Baseline: 1 model call. DeepAgents and DSH: up to 6 model calls and 4 trial tool calls per attempt. DSH adds 87 recovery attempts; full environment and reasoning parity is unverified. DSH has no paired lift; these are not equal-cost causal estimates.
Evidence status & metric definitions
“Metric unknown” means the selected metric cannot be assessed, including failed execution or unavailable outputs. It is different from a task whose final status is unknown. Neither is dropped or counted as a success.

HF-style counts are checked against archived task flags. Full-replication counts for Sol and Opus come from accepted summaries; all other displayed runs, including DSH, have per-task local flags. This refresh does not rerun or rescore any experiment.
Per-run archive files remain frozen, including their original publication metadata. This page is a new display derived from those archives. GPT-5.5 and unarchived experiments are not included in this edition.
