When Washington ordered Anthropic to shut off access to its most advanced AI model, it did not shut off everyone. Some of the organisations Anthropic had chosen early to test Mythos have kept their access to a preview of the system, even as other versions went dark under a US export directive, according to a Bloomberg report.
The mechanics matter here. Anthropic had limited what it calls Mythos Preview to roughly 200 organisations, including the US government, under its Glasswing programme, after the model demonstrated an unusual capability: it identified thousands of software vulnerabilities.
A less powerful version of Mythos was released more widely, then disabled when Commerce ordered Anthropic to suspend access for all foreign nationals on national-security grounds. The preview, for some, survived the cut.
Two named firms confirmed they retained access. Dragos, the industrial-cybersecurity company that Accenture is now acquiring a majority stake in, and Cisco Systems both told Bloomberg they still had Mythos Preview.
