Charts

Partial coverage. Claude Code – GLM-5.3 (max, default): 21 of 147 Earth-Bench V2 tasks; 96 of 173 GeoBenchX tasks; GS-QA2 incomplete. Grey placeholders identify these entries in the index, cost and output token charts; their height does not represent a value. Comparable bars appear when first-attempt coverage is complete. Their available results remain in the side-by-side table.
