In June Anthropic apologized for silently rerouting flagged Fable 5 requests. The Sept 8 NSA/CISA/FBI advisory tells labs to downgrade suspected distillers without telling them. Does the June promise still hold?

In June, Anthropic apologized for silently rerouting flagged Fable 5 requests to Opus 4.8, promising that future flagged requests would visibly fall back to Opus 4.8 or return a refusal reason. However, a September 8 NSA/CISA/FBI advisory instructed labs to downgrade suspected distillers without notification. This raises questions about whether Anthropic's June promise of transparency still holds, especially since the September 30 Fable 5.1 update tightened anti-distillation measures but did not explicitly mention downgrades.
