Anthropic disabled its new Fable 5 and Mythos 5 models following a U.S. Commerce Department directive regarding export controls and national security concerns.Summary
Anthropic has abruptly disabled its newly launched Fable 5 and Mythos 5 models in response to a directive from the U.S. Commerce Department. The government mandate imposes export controls due to national security concerns, specifically regarding reported jailbreaks that could allow the models to assist with cybersecurity, chemical, or biological threats. While the administration seeks time to harden security measures, Anthropic noted that the government provided only verbal evidence of a narrow, non-universal jailbreak involving software vulnerability analysis. The company maintains that these risks are comparable to those present in other publicly available models.
