• ENISA has been given access to Anthropic's Mythos 5 and is now testing it alongside OpenAI’s GPT-6 Astra, a European Commission spokesperson said.
• Anthropic announced in April that Mythos could outperform humans at finding and exploiting security vulnerabilities.
• The comparison with OpenAI is what makes the timing interesting.
• ENISA now has two frontier models to test within days of each other, one from a company that had just released its model and another that had spent months negotiating access.
