Senior Anthropic staff will meet Trump administration officials Monday to address an export control order received Friday that requires blocking foreign access to the firm's newest AI systems over an unspecified national security threat. The action follows the Pentagon's March designation of the company as a supply chain risk and continues amid active litigation seeking to reverse that label.

Monday talks concluded without a deal or resolution; export controls on Fable 5 and Mythos 5 remain in place, with officials indicating it may take more than a few days to resolve.
Anthropic stated both parties are working quickly to resolve the export restrictions, in its first public comments since the models were pulled; talks also involved National Cyber Director Sean Cairncross.
Anthropic staff held in-person meetings Monday with senior Trump administration officials at the Commerce Department to discuss the export restrictions and potential resolution, the first such sit-downs following the Friday directive.
To comply, the firm immediately cut off every customer from the two releases.
The person added that Anthropic had received no prior warning about any national security concern before the order.

Tesla and SpaceX have confirmed Grimes County, Texas as the site for their Terafab semiconductor megafactory, with the first phase costing roughly $16.8 billion. The project targets the largest chip manufacturing facility on the planet to supply over 1 terawatt of compute per year that exceeds current and future global production capacity.
OpenAI has filed a motion asking a federal judge to dismiss Apple's trade secrets lawsuit, describing the claims as meritless. The dispute, which follows a July suit and this week's injunction request from Apple, highlights tensions after their prior partnership on Siri and OpenAI's hardware push.
Meta has released an early beta of Muse Code, a terminal-based coding agent driven by the updated Muse Spark 1.2 model and positioned against Anthropic's Claude Code and OpenAI's Codex. Substantially lower rates, including a contributor plan at $0.10 for every million tokens received, may encourage migration away from higher-priced options such as Anthropic's Sonnet 5.
