Old steam-train drawing rebuilt in Blender as 3,295 editable objects

Tom Krcha, founder of Pendev, handed GPT-6 Astra an old drawing of a steam train and asked for a Blender reconstruction. A few minutes later it had modelled 3,295 fully editable, detailed objects, and you can tell it how simple or detailed to go.

So how good really is GPT-6 Astra at 3D modeling?
I took an old drawing of a steam train, gave it to Astra to reconstruct it in Blender. After few minutes it crafted 3,295 fully editable detailed objects with beautiful geometry. You can obviously tell it how detailed or simplified you want it. Go build your own transport tycoon 😎
