Jamie Dimon warns about Anthropic Mythos AI access

JPMorgan CEO Jamie Dimon warned that broad public access to Anthropic's Mythos AI model—capable of identifying software vulnerabilities—poses serious national security risks, comparing it to distributing ballistic missiles. The bank is among a select group with restricted access and has deployed hundreds of staff to stress-test systems against the model's findings.

This Wire brief sits within Fusion42's coverage of AI Frontier Models and Cybersecurity. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

Either integrate with Mythos through Glasswing before access closes further, or build what Mythos can't do yet.
