Anthropic limits access to Mythos, its new cybersecurity AI model

Anthropic has launched a new cybersecurity AI model to a select group of customers, including Amazon, Apple, and Microsoft, days after details about the project were leaked online.\

Anthropic said the software can identify cyber vulnerabilities at a scale beyond human capacity, but it could also develop ways to exploit these vulnerabilities, which bad actors could use. The company said the model could “reshape” cyber security practices and does not plan a broad release.
