Early this morning, multiple foreign media outlets reported that Anthropic's termination of access to the Fable 5 and Mythos 5 models may be linked to Amazon CEO Andy Jassy. According to The Wall Street Journal, Amazon researchers discovered that information usable for cyberattacks could be obtained while using Anthropic's Claude Fable 5 model. Subsequently, the U.S. government imposed export control restrictions on these two models. Amazon Web Services was also affected, revoking access to these two models across all regions. Anthropic CEO Dario Amodei spoke with U.S. government officials, explaining that the so-called jailbreak vulnerability did not pose a high security threshold and that similar issues might exist in other large models. However, the U.S. government still decided to implement export controls. Currently, the U.S. government hopes Anthropic will promptly address security issues to lift the export controls and re-release the models. Anthropic has disabled access to these two models for all users, apologized to affected customers, and stated that it is working diligently to restore access as soon as possible.
