Fable 5 Punished by Safety Guardrails After Removing Malware
om_kesti · reddit · 2026-07-07
When a user asked Fable 5 to check the registry, the model unexpectedly discovered a hidden PowerShell persistence malicious script that downloaded remote payloads upon every login. Following the user's instructions to neutralize the threat, Fable 5 successfully deleted the relevant registry keys and eradicated the malware.
However, right after successfully completing this "incident response," Fable 5's safety guardrails were triggered. Because the conversation involved "cybersecurity work," the system forcibly downgraded the session to Opus 4.8.
The ironic outcome of an AI acting as an elite antivirus to clear a real virus, only to be immediately "punished" by its own safety filters, has sparked widespread resonance.
