Anthropic is expanding testing of Mythos, its latest cybersecurity model, by bringing in around 150 additional partners.
The company, seen as the main rival to OpenAI’s ChatGPT, announced in April that it was launching Mythos, a model it said “has already found thousands of high-severity vulnerabilities, including some in every major operating system and web browser.”
Mythos was initially restricted to 50 initial partners who had access to the preview model under the so-called “Project Glasswing” and, according to Anthropic, have used it to find more than 10,000 high or critical security flaws.
