GPT-6 Astra leaps ahead in world modeling and reasoning, but coding gap vs Fable 5.1 stays slim

A user reviewed OpenAI's GPT-6 Astra, arguing the model went hard on pre-training: world modeling, math/abstraction, spatial and visual reasoning, and environment interaction all appear to leapfrog competing models.
The interesting caveat: in coding, the gap versus Fable 5.1 is not that big, suggesting programming remains a closely contested frontier.
