OpenAI Astra demo: blueprint to Blender model to Unreal archviz, token costs high
LinusEkenstam · x · 2026-09-04
Linus Ekenstam shared an OpenAI Astra demo where the AI goes from a blueprint to generating a 3D model in Blender, then builds out a full architectural visualization in Unreal Engine, largely end-to-end.
He notes the workflow was "tokenmaxxing hard," meaning the token/API costs were likely substantial. The demo showcases Astra's potential as a multi-step design agent, with cost remaining the main bottleneck for real adoption.
