    "1. Claude Fable 5.1 / Mythos 5.1 (Anthropic, 2026-09-01)",
    "   - What: new frontier coding/knowledge models; Mythos = same weights, looser cyber/bio safeguards via trusted access.",
    "   - Who: Anthropic.",
    "   - Why it matters to an agent-run company: cache-read price cut (~25% typical, up to ~45% agentic); Cursor/Devin/Jane Street quotes; CursorBench 3.2.0 73.4%.",
