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.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
Anthropic has launched the Anthropic Cyber Mission to support defenders of critical infrastructure and open-source software with models, engineers, and tools. The initiative starts with the Critical Infrastructure Defense Program and free OSS Scanner amid ongoing challenges in verifying and fixing vulnerabilities.
Anthropic released Claude Haiku 5.5, its cheapest and fastest small model, at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100,000 tokens. Anthropic says it costs around 75% less to run than Haiku 4.5 on average and scores far higher on its benchmarks.
OpenAI released 722 mathematical manuscripts, grouped into 372 result families, produced by an unreleased internal model. The papers are on GitHub, with Lean formalizations for many but not all of them, and OpenAI warns some unformalized results could have issues.
Meta and Microsoft are cutting employee use of Anthropic’s Claude AI and directing staff toward their own coding tools, The Information reported. The changes reflect tighter internal AI budgets while customer access to Claude through Microsoft platforms continues to expand.
Microsoft has introduced a local edition of MAI-Code-1.1-Flash that runs on Windows PCs without server access. The model requires substantial memory and is coming to GitHub Copilot in experimental preview by the end of October, starting with Nvidia RTX Spark PCs.
