Summary
Anthropic completely shut off access to its Mythos 5 and Fable 5 models Friday night, days after they were launched. An Axios report cited an administration official saying that the administration is concerned by reports of a jailbreak that reportedly gets around broad classifier-based safeguards meant to block Fable 5 prompts regarding cybersecurity, chemistry, and biology. In its Friday night announcement post, Anthropic said the government has only provided it with “verbal evidence of a potential narrow, non-universal jailbreak” that involves getting Fable 5 to review a specific codebase for software flaws. “We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users,” Anthropic writes.
