Bloomberg: Anthropic Mythos Preview Partners Including Amazon, Apple, Google, and Microsoft Retained Model Access Despite US Shutdown Order

Bloomberg reports that approximately 50 organizations given pre-launch access to Anthropic's Mythos Preview — including Amazon, Apple, Google, Microsoft, and Nvidia for defensive cybersecurity work — have retained that access despite the US government's order shutting down the commercial Fable 5 and Mythos 5 models. The carve-out exists because the export control directive targeted the publicly launched commercial models, not the pre-release preview version distributed to Anthropic's elite defensive cybersecurity partner program. The disclosure reveals the shutdown created a two-tier access structure in which the world's most powerful commercial AI model remains accessible to a small set of vetted enterprise partners while the broader market is locked out.
