The Same Model Scores 52 or 81 Percent Depending on the Code Wrapped Around It News
A new agent harness lifts Qwen 3.7-Plus from 51.8% to 80.7% on a long-horizon coding benchmark without touching the model, by keeping task state outside the conversation and updating it only from facts a read-only auditor verified in the environment.
harness-training Tool
A small PyTorch-shaped framework for treating an agent harness as the thing being trained: the harness file is the weights, an improvement agent is the gradient estimator, a deterministic task panel is the loss, and promotion or rejection is the optimizer step. Built around reproducible, deterministic runs.
