Analysis: Claude Routes Requests to Opus 4.8 via Safety Layer

rohanpaul_ai · x · 2026-07-03

rohanpaulai clarifies that the Fable/Mythos models themselves haven't changed. The perceived "nerf" is actually due to a new safety classifier/routing layer intercepting more prompts and diverting them to the fallback model Opus 4.8, rather than a degradation in Fable 5's native capabilities. In other words, user requests might never actually reach Fable 5, being rerouted to Opus 4.8 at the routing layer instead.
