Anthropic’s Mythos 5 is back

After a lengthy negotiation process with the Trump administration, Anthropic's Mythos 5 is partially back in action for select organizations. The public-facing Fable 5 model remains in limbo with no clear timeline for rollout. A letter from Commerce Secretary Howard Lutnick to Anthropic co-founder Tom Brown indicates a revision to the license requirements. The negotiations had lasted for two weeks, and the outcome suggests progress but also ongoing uncertainties regarding the Mythos-class models.
