Mythos seems to be a very capable model based on available information, but it is not a cybersecurity model - it is an advanced general purpose model that happens to be good at cyber because it is good at a bunch of things. Anthropic stated that they were worried about cybersecurity risk, and their efforts mean it is a restricted model with lots of government attention. OpenAI and Google will pass the same threshold soon (and may already have with unreleased models). and the question is whether they are as worried about cybersecurity risks, or whether they think their guardrails will hold. Currently, the degree to which models have cyberrisk is entirely self-reported and not regulated. That means that OpenAI and Google could release Mythos-class models if they want, by assessing the risk differently and making different decisions. Does that mean Anthropic is at a disadvantage because it can't release its equivalent model? Will OpenAI and Google also be somehow restricted from releasing their Mythos competitor. It all seems pretty unclear right now.
