Researchers say AI just broke every benchmark for autonomous cyber capability

Researchers found that AI models, including Anthropic's Claude Mythos Preview and OpenAI's GPT-5.5, have surpassed benchmarks for autonomous cyber capability, significantly outperforming previous trends. The AI Security Institute and Palo Alto Networks conducted separate tests, with results showing the models' ability to complete complex cybersecurity tasks autonomously. This breakthrough has significant implications for the field of artificial intelligence.
