BlockBeats News, July 3rd, According to a report from the well-known vibe coding community BridgeMind yesterday evening, data shows that the post-unblocking Fable 5 is significantly restricted, and benchmark tests have revealed a substantial decline in its overall capabilities.

After analysis, BridgeMind suggested that the reason for Fable 5's performance decline is not due to model degradation, but rather the routing (protection measures) causing it to more frequently fall back to Opus 4.8. In short, Fable 5 has been "caged in".
