Anthropic keeps 'Mythos' private

- Anthropic decided not to publicly release its 'Mythos' model, citing danger concerns and limiting access to a small set of partners and governments. - Reports say Mythos access was restricted to roughly 40 organizations in the U.S. and U.K., with central banks and intelligence agencies raising cyber‑risk alarms. - Anthropic’s choice contrasts with internal pressure for releases from figures like Sam Altman and highlights governance‑first gating for sensitive models.
