Short summary

In a rigorous comparison, Claude Fable's theoretical superiority lost to GPT-5.6 Soul's practical effectiveness. The insight: model differentiation is shifting from raw intelligence to collaborability, taste-alignment, and real-world outcome delivery. Human judgment (weighted 70% over machine scoring) remains the final arbiter.

• •Claude Fable is theoretically superior but less practical for real-world collaboration; GPT-5.6 Soul wins on usability and shipping outcomes
• •Model differentiation now centers on collaborability, taste, and absence of slop rather than benchmark scores alone
• •Human judgment and practical effectiveness are becoming the true competitive differentiators in model selection
