WorldofAI · youtube · 2026-11-08
WorldofAI rounds up this week's model leaks: a mystery model codenamed Claude Donut EAP has surfaced in Cognition's Devin CLI, mapped to a new Claude family called Silicon, suggesting Anthropic is secretly testing a next-gen model line. Another hidden model, Obsidian 3, is reportedly beating Claude Opus 5.5 on coding benchmarks. All claims are third-party leaks/benchmarks, unconfirmed by Anthropic; the creator re-ran tests with his own woaibench.ai tool.
