Trial by Trace - Claude Code - Agent Score: leaderboard

Trial by Trace measures model task performance under a named native agent harness on 95 mechanism-focused tasks per model. Agent Pass requires all agent task criteria to pass; Agent Score is criterion-level performance. Harness-only scores, costs and mixed Agent/Harness composites are not admitted. arXiv v1; 95 tasks per model/harness; one selected execution including recovery replacements; DeepSeek-V4-Flash semantic judge with variable scoring budgets; native harness versions, model API snapshots and reasoning effort unreported. Metric: Agent Score (%), higher is better.

Metric: Agent Score (%). Source: tracelite.ai. Saturation forecast: Rough model projection: around 2026. 9 models tracked.
