Technical approach

As reported
Physics training

Real data and physical laws

Trained on experimental results and physics equations, not text. Grounds models in real constraints.

Design automation

End-to-end CAD to manufacturing

Optimizes designs by simulating candidates against physics and cost constraints.

Multi-domain

Aerospace, pharma, semiconductors

Trains on diverse domains to learn physical optimization principles across industries.
