One new research article published: Claude Fable 5.1 & Mythos 5.1 — the most significant capability leap in Anthropic's lineage with 77.9% OSWorld 2.0, 52.6% Terminal-Bench-Science, 10× protein binding affinity, and the Enterprise Frontier Safeguards architecture.
On September 1, 2026, Anthropic released Claude Fable 5.1 and Claude Mythos 5.1 — the world's most advanced models for coding, knowledge work, and scientific research — achieving 77.9% on OSWorld 2.0, 52.6% on Terminal-Bench-Science, and designing high-affinity protein binders with near-50% hit rates, while introducing Enterprise Frontier Safeguards (EFS) to resolve the zero-data-retention vs. security monitoring dilemma.
