The K3 repo's tables put it ahead on SWE-Marathon (42.0 vs 35.0 for Fable 5 and 39.0 for GPT-5.6 Sol), BrowseComp (91.2 vs 88.0 and 90.4), MCPMark-Verified (94.5 vs 87.4 and 92.9), AutomationBench (30.8), and SpreadsheetBench 2 (34.8). It trails on HLE-Full (43.5/56.0 vs 53.3/63.0), DeepSWE (67.5 vs 73.0), and GDPval-AA v2 Elo (1686 vs 1747). The pattern is consistent enough to route on: long-horizon tool use to K3, hardest reasoning elsewhere.
