Astra Finishes Inline-6 Engine Model Faster Than Fable 5.1

Bradley Rothenberg, CEO of nTopology, posted that he tested Astra and Fable 5.1 on modeling a parametric inline-6 engine inside nTop. The attached screenshot shows an nTop interface titled "I6 Astra | 3.2 L preliminary design" with a gray-and-black 3D engine model and orange accents. Rothenberg wrote that both outputs remain far from production-ready yet Astra completed the work in under two hours while Fable 5.1 required six. He described Astra as showing a noticeable advance in an LLM's spatial understanding.
