Hedra

Physical world models and visual AI

Hedra is a research and infrastructure lab building physical world models and the inference systems to deploy them at scale, laying foundations for full-stack visual intelligence. Its API serves both first- and third-party models to production customers, and its agent works within a single workflow to create content from scratch, manipulate existing assets, critique its own outputs and repurpose them on demand — the self-critique step being what separates a usable pipeline from a generator that needs a human reviewing every frame. The company is scaling from frontier research into infrastructure others will build on.
