White House Fable Jailbreak Report: Security Expert Says Model Behaved as Intended
Simon Willison's Weblog·42 days ago·Incident
Anthropic shared the White House's report on an alleged Fable jailbreak with cybersecurity expert Katie Moussouris for an independent appraisal.
The report documented IT experts prompting Fable with deliberately insecure code; the model refused explicit security-review requests but complied when asked to 'fix' the code instead.
Moussouris, who says she is unpaid by Anthropic, concluded this differential behavior was 'the model working as intended' for legitimate cyberdefense purposes.
