Fable produces fewer defects for just $0.08 more per shipped AI line than Opus. Thatβs what we observed with Fable 5 versus Opus 4.7 even though Fable handled a more complex task mix (94% vs. 83%). Composer was also a clear cost outlier on the Pareto curve. Span makes this https://t.co/66Mc5aMWh7

Does anyone actually have any evidence that model routers work in terms of $/merged AI line? Switching models mid session incurs a potentially massive cache penalty. Choosing a dumber model than is required for a task increases rework and chance of escaped defect.
