    Jack Roberts and Nick Saraev discuss reports that Anthropic has completed Mythos 2 without plans for a public release. They argue that unreleased internal systems make the apparent gap between open models and the frontier look smaller than the real capability gap.

    Roberts and Saraev connect restricted access to cybersecurity, alignment and national-security concerns. They acknowledge that the details remain opaque, while suggesting that government interest in powerful models could shape what laboratories make available to ordinary users.

    The hosts also examine Grok 4.6's stronger agentic benchmark result and Sam Altman's prediction that ChatGPT could gain much broader personal context. They distinguish raw model intelligence from practical tool use, then weigh the productivity benefits of persistent context against the need to keep personal data from becoming an uncontrolled surveillance surface.
