Claude Mythos and misguided open-weight fearmongering

Interconnects · 6 months ago · 36

Anthropic announced Claude Mythos, a cybersecurity-focused model with strong stated abilities, prompting renewed warnings that open-weight versions would enable widespread attacks on unprepared infrastructure. Running such a model requires approximately 100 H100 GPUs costing roughly $10,000 daily, meaning only well-resourced actors could deploy it rather than individual attackers. The author argues for specific research into the actual cybersecurity risks and capability gaps between open and closed models rather than broad restrictions that could cede AI development to other countries.
