Mythos is an AI model developed by Anthropic that excels in coding performance. Anthropic has refused to make this model publicly available because it has a high ability to discover and exploit software vulnerabilities. Instead, they have stated their policy of providing access only to a limited number of organizations to proactively discover and address vulnerabilities.

Approximately 40 organizations have already been granted access to Mythos, enabling them to fix vulnerabilities discovered by Mythos. Anthropic has agreed, at the request of the White House, not to distribute it more widely.

It has now been revealed that Anthropic plans to discuss the impact of Mythos on the financial system with the FSB.

It is reported that this initiative was requested by Andrew Bailey, Governor of the Bank of England and Chairman of the Financial Services Board (FSB). Bailey had previously spoken out about the threat posed by Mythos and had instructed the Treasury to further strengthen core cybersecurity measures for businesses.



The Financial Services Board (FSB) is an organization that works to address vulnerabilities in the financial system and promote coordination among authorities responsible for financial system stability. It includes officials from the finance ministries of countries such as Japan, the United States, and the United Kingdom, as well as central bank officials and securities regulators. An FSB spokesperson confirmed the plan for discussions and said, 'We welcome discussions with companies like Anthropic regarding new and frontier risks to global stability.'

The FSB is currently preparing a report outlining 'sound practices' regarding the implementation of AI in the financial system, which is scheduled to be released for public comment in June 2026.



Anthropic has already announced that 'Mythos has discovered thousands of critical vulnerabilities, including those in all major operating systems and some web browsers,' adding that 'the impact on the economy, public, and national security could be serious.'

Requests for explanations regarding access to and capabilities of Mythos have poured in from around the world, and Anthropic has agreed to provide a high level of explanation to some organizations, including the European Commission.
