Sourcing per dimension: coding=SWE-bench Verified 88.6%; instruction_following=estimated from 4.5/4.6 lineage (IFEval ~92, MMLU-Pro ~89) tempered by AA IFBench 62.2%; math_reasoning=AIME 2026 95.7% + USAMO 2026 96.7%; world_knowledge=GPQA Diamond 93.6%; planning_agentic=Terminal-Bench 2.1 74.6% + MCP-Atlas 82.2% (the tau2 Telecom 94.4% figure was de-weighted as display-only); creative_synthesis=imputed. Opus 4.8 sits just below the newer flagship Fable 5 overall but leads it on refresh-era math (USAMO/AIME 2026) and ties/edges it on GPQA. The matrix was rescaled to widen tier separation for routing. A `measured` extraction on the frozen probe set overrides this. See README.md."
