The Trump administration lifts restrictions on Anthropic’s latest Claude chatbot versions after a cybersecurity concern, ending a ban that lasted about a week. Multiple reports say the action follows a warning related to the models’ cybersecurity risk. Anthropic states that, as of Tuesday night, its AI model “Claude Fable 5” is now widely available again. The company also reports that it is restoring access to its most powerful model, “Mythos.” The outlets characterize the change as a reversal of the earlier limits placed on Anthropic’s releases, with officials citing cybersecurity as the reason for the initial restrictions. While the reports focus on the lifting of the ban and the return of access to Claude Fable 5 and Mythos, they do not provide extensive public detail about the specific cybersecurity issue or the technical measures behind the decision. Overall, the coverage indicates the restrictions are removed and Anthropic can resume broader availability of the affected Claude model updates.
