Higgsfield has posted a new computer-use demo in which OpenAI’s GPT-6 Astra explores a 3D castle in Blender, using the company’s Supercomputer stack and Blender plugin, and treating a dragon as the site’s security detail. The clip is one of a cluster of spatial builds the studio has released since Astra shipped on September 3, 2026, pairing the model with Higgsfield’s agent tools rather than a text-only prompt.
