EU's cybersecurity agency granted access to Mythos 5 AI model, Commission says
The agency will use the restricted model to stress-test cyber defenses after Anthropic limited access to about 200 approved partners.
- On Thursday, the European Union's cybersecurity agency ENISA gained access to Anthropic's Mythos 5 model, with European Commission spokesperson Thomas Regnier confirming the agency is now testing it alongside OpenAI's GPT-6 Astra.
- Anthropic had restricted Mythos to roughly 200 partners via Project Glasswing, collaborating with Washington due to the model's ability to exploit cyber vulnerabilities with unprecedented speed. US export controls subsequently barred access for non-American users.
- Brussels pressed for access amid concerns that Washington might trigger a "kill switch" on advanced US technologies. European Commission holds significant regulatory powers under the EU AI Act, making companies wary of withholding information.
- Mythos took five months from Anthropic's original announcement to reach ENISA, ending protracted negotiations. European Commission spokesperson Regnier noted ENISA also holds access to OpenAI's GPT-5.6-Cyber model for testing.
- Regulators now utilize Article 55 to examine general-purpose AI models directly rather than relying on corporate disclosures. EU's AI Office began enforcement with a 36-person team to monitor systemic risks.
