AISI Research Finds GPT-5.5 Matches Anthropic Mythos Preview on Cybersecurity Tests
The UK's AI Security Institute released research showing OpenAI's GPT-5.5 achieved 71.4% on Expert-level cybersecurity tasks versus Anthropic's Mythos Preview at 68.6%—within margin of error. Both models succeeded on the previously impossible "The Last Ones" test (GPT-5.5: 3/10, Mythos: 2/10), though both failed the "Cooling Tower" power plant simulation. Sam Altman criticized Anthropic's restricted release as "fear-based marketing," suggesting the capabilities reflect general AI improvements rather than a model-specific breakthrough.
