05:05 AM EDT, 05/19/2026 (MT Newswires) -- Amazon ( AMZN )-backed (AMZN) Anthropic recently began allowing users of its AI model, Mythos, to share cybersecurity threats, The Wall Street Journal reported Monday.

The company previously allowed roughly 50 large companies and organizations managing critical digital infrastructure to access Mythos, which can find software vulnerabilities much more efficiently than humans.

The Mythos users initially signed confidentiality agreements to ensure cyber risk information wasn't shared, an Anthropic spokeswoman told the WSJ.

"Confidentiality protections were something partners asked for at the outset and were built into agreements partners signed," the spokeswoman was cited as saying. "As the program has matured, we've adapted them to ensure key information can be shared broadly, including outside the program, for maximum defensive impact."

Anthropic did not immediately respond to an out-of-office-hours request for comment from MT Newswires.
