JPMorgan CEO Dimon says Anthropic’s Mythos AI risks are a ‘real issue’

July 15 (Reuters) – JPMorgan Chase CEO Jamie Dimon said on Wednesday that risks posed by Anthropic’s Mythos AI model are a “real issue” ​that the U.S. government is on ‌top of, underscoring concerns about the powerful model that have caused Washington to intervene.

Dimon, speaking at Senator Dave McCormick’s Pennsylvania Defense and Innovation Summit, added that access to ‌advanced ​AI capabilities must be controlled, ⁠saying “you’re giving ballistic missiles ⁠to individuals with Mythos.”

U.S.-based Anthropic released Mythos in April to a select group that included JPMorgan. The model has attracted interest from banks ​because it is considered among the most advanced AI systems for identifying cybersecurity vulnerabilities, helping ⁠firms uncover and fix weaknesses ⁠more quickly.

However, in June, the U.S. ​government ordered Anthropic to restrict access to its top ​AI models, Fable 5 and Mythos 5, to ‌foreign nationals over national security concerns, forcing the company to cut off worldwide access.

The government later removed restrictions on the models after Anthropic implemented ⁠new safeguards.

Governments and tech companies are grappling with AI safety concerns, including the misuse of systems capable of ⁠identifying software ‌vulnerabilities. Washington has stepped up oversight ⁠of new model releases amid fears ​that ‌advanced AI could be exploited by ​military intelligence ⁠in China, Russia or other countries of concern.

Anthropic could not be immediately reached for comment on Dimon’s remarks outside regular business hours.
