Bank of America Keeps 1,000 Contractors on Mythos-Linked Repairs

Bank of America kept 1,000 contractors on software repairs after hiring them in the second quarter to address flaws identified by Claude Mythos and other advanced AI models.

The contractors joined roughly 3,000 employees already on the bank’s AI-related software patching effort, adding about one-third to its staffing. Bank of America CEO Brian Moynihan told analysts Oct. 14 that the contractors were still working with the bank.

Moynihan said the added spending was temporary and costs would decline as the repair backlog shrank. He did not separate Mythos costs from broader remediation spending.

The bank spent more than $200 million in the third quarter on software remediation and anti-money-laundering matters combined. It also recorded $1.2 billion in regulatory settlement charges for the quarter.

Anthropic launched Claude Mythos Preview and Project Glasswing on April 7, offering selected organizations access to the model for defensive security work on critical software. Mythos has identified thousands of vulnerabilities.
