Summary

Anthropic's unreleased "Mythos" model, previously described as too powerful and dangerous for public release, was reportedly accessed by unauthorized users. Despite Anthropic's claims that the model is too scary to be released, the company states there is no evidence of this unauthorized access impacting its systems or being used for nefarious purposes. Sam Altman, on the Core Memory podcast, critically commented on this marketing strategy, likening it to selling a "bomb shelter" after announcing the creation of a "bomb," implying a deliberate hype generation around a powerful, unreleased AI model.

Key takeaway

For CTOs and VPs of Engineering evaluating AI model release strategies, consider that marketing a model as "too powerful to release" can create significant security risks by incentivizing unauthorized access. Your communication around advanced models should balance innovation with realistic risk assessment to avoid inadvertently challenging malicious actors.
