The Gold Eagle Clearinghouse Tested Vorp Labs' reconstructed timeline of the White House's intervention in frontier model access: the Commerce Department's Jun‑12 export directive that briefly killed Claude Fable 5/Anthropic Mythos 5 for all customers, the GPT‑5.6 staggered release, and the new "Gold Eagle" clearinghouse (EO 14409). Separates verified facts from single‑source standing‑approval claims, which the White House officially denies. [Vorp Labs / CNBC] 7 Open‑Weight AI Models Now Match Frontier Cyber Skill from Four Months Prior UK AISI's first public measurement of the open‑weight cyber gap finds GLM‑5.2 and DeepSeek V4‑Pro trail Anthropic's Opus 4.6/4.5 by only 4‑7 months (down from 6‑10 months last year). Closed‑model cyber performance is doubling every 4.7 months, compressing the gap toward a moving frontier. Includes a 32‑step autonomous cyber‑range test ("The Last Ones").
