OpenAI's GPT-6 Astra Builds Houdini Crowd Simulation in Higgsfield Demo

OpenAI's GPT-6 Astra has been shown building a crowd simulation in SideFX Houdini through a Higgsfield workflow, combining running characters, collisions and ragdoll dynamics into a cascading pileup. The example is a compact demonstration of an agent moving from scene logic to a physically evolving 3D result.
