US Commerce Department Clears Anthropic Mythos 5 AI Model for Limited Release After NSA Breach Scare
Commerce Secretary Howard Lutnick wrote to Anthropic's chief compute officer Friday, authorizing Mythos 5's release to "certain trusted partners" after the government suspended the model two weeks ago following an authorized NSA red-team evaluation on June 11 in which Mythos breached nearly all classified systems within hours, prompting export-control concerns that foreign nationals could bypass its security guardrails
The partial clearance formalizes a two-track deployment regime separating purpose-built cybersecurity tools from general-purpose frontier models, converting what began as an incident-response suspension into the first US export-control action targeting an AI model directly. Glasswing's restricted restart restores competitive footing for approved clients, but Fable 5's continued hold keeps Anthropic's broader commercial posture and IPO trajectory hostage to an undisclosed government timeline. Low confidence governs the assessment, reflecting the single-source evidentiary base and Commerce's omission of any stated criteria for restoring Fable 5. Brown's direct management of Lutnick negotiations while Amodei stepped back reads as founder-tier commercial leverage rather than technical compliance. The partial lift may reflect the competitive cost to US firms of sustained access restrictions more than genuine resolution of the government's underlying security concerns.
