Fable 5 and Mythos 5 remain suspended: “The ball is in Anthropic’s court”
Anthropic has suspended its Fable 5 and Mythos 5 models from its API following reports that users were able to bypass the models' safety guardrails. The suspension remains in effect, with Anthropic yet to announce a timeline for reinstatement or any modifications to the models. The developer community is now waiting on Anthropic to decide the next steps, as the models were popular for creative writing and role-playing tasks. The incident highlights ongoing challenges in aligning large language models with safety requirements, especially as models become more capable. Anthropic has not disclosed specific details about the vulnerabilities or whether they plan to release updated versions.
Developers relying on these models must find alternatives until Anthropic resolves the safety bypass issues.
