Model-catalog knowledge update log

2026-08-12

  • Update: Live refresh via process:update-model-catalog from arena.ai/leaderboard/text (Aug 12, 2026; 390 models; 7.8M votes).
  • Attested — existing catalog scores moved to the live board where the name matched exactly, via punctuation / :free aliases, or as a same-model alias that already shared a score. Typical drift is 1–3 Elo. Named examples: qwen3.8-max 1497 → 1491, kimi-k3-max 1485 → 1489, claude-opus-5-max 1488 → 1491, muse-spark-1.2-xhigh 1498 → 1499.
  • New catalog entries — grok-4.6 / grok-4.6-high (1464), muse-glimmer (1426), solar-pro4 (1378), nemotron-3.5-lightning (1350).
  • Not copied — dated snapshots onto a different dated/generic id; thinking / xHigh tiers onto the base id; unrelated ids that only shared a source line (gpt-4o-mini vs gpt-oss-20b, command-r vs command-r-08-2024, glm-4-plus vs glm-4-plus-0111).
  • Estimates — left unchanged except where an id was newly attested.
  • Initialization: Created OKF model-catalog bundle (arena scores + matching policy). Runtime source of truth remains ModelCatalog.kt.
