I made a 2M views Zillow photos → 3D walkthrough video with Astra.
Reran it on a normal house with Opus 5.5. One shot. Huge improvement and indistinguishable from a real walkthrough 🤯 The one flaw was probably my fault.
Fable 5.1 was not even in the game (in the comment), yet Opus 5.5 eclipsed Astra. Wild progress @AnthropicAI
People asked about the code and model, so I open-sourced it 👇

Zillow listing photos turned into a 3D house walkthrough video
Yunfan Ye, an AI researcher formerly at Google and Meta, had GPT-6 Astra model a house from its Zillow photos and cut a promo video, then reran it on an ordinary house with Claude Opus 5.5 in one shot. They call the result indistinguishable from a real walkthrough, and the code is open source.
