Anthropic's new Mythos AI model is causing concern among governments and companies that it could outpace current cyber security defences, turbocharge hacking and expose weaknesses faster than they can be fixed. The model has shown its ability to detect software flaws faster than humans but also generates exploits to exploit them. This has led senior international financial officials and government ministers to investigate the dangers. The UK's AI minister Kanishka Narayan warned of "we should be worried" about the capabilities of the model. This comes after OpenAI released its own advanced cyber model with similar capabilities.
