Luminary Cloud

Luminary Cloud is a US software company that builds a Physics AI platform for engineering teams. The platform helps teams turn simulation, test and operational data into models that predict how a design will behave.

The company calls these models Large Physics Models. They learn how designs flow, deform, heat and move. They then predict the behavior of a new design in less than a second. Luminary says engineers can check how a system behaves in milliseconds instead of hours or days. It says accuracy is checked against high-fidelity simulation and physical tests.

The platform covers the full path from data to prediction. First, it generates and unifies data. It can run simulations across proprietary, commercial and open-source solvers. It also takes in test and operational data and keeps track of where each file came from. Next, teams train and validate models for fluid flow, structures, thermal and electromagnetics. The tools show how accurate a model is and where its predictions can be trusted.

Models are then deployed into CAD, CAE and analysis workflows. Luminary offers APIs, SDKs and an AI assistant to help embed them in tools engineers already use. The platform tracks model health and can trigger retraining. A model registry shows what each model predicts, which data it used, what changed between releases and where it is approved to run. It can run in the cloud, in private setups or in a hybrid mix.

The company serves aerospace, automotive, defense and industrial machinery. Otto Aviation runs its own flight sciences on the platform. Northrop Grumman Space Systems is bringing Physics AI to its design engineers. Honda uses a Luminary foundation model for vehicle aerodynamics.

Luminary also runs Physics AI DevDay on November 17, 2026. The event has a keynote, technical deep dives and a hands-on workshop, and it features NVIDIA.
