Arena Physica will train its next electromagnetism AI model on Oak Ridge's AMD supercomputer

Nov 12, 2026
The startup's Heaviside model predicts how electromagnetic fields behave in chips and antennas; the next versions will train on the Lux supercomputer.

Startup Arena Physica will train the next versions of Heaviside, its AI model for electromagnetism, on the Lux AI supercomputer at Oak Ridge National Laboratory, which runs on AMD hardware, the company said in a press release.

Heaviside predicts how electromagnetic fields behave in a physical design, work that normally needs slow, expensive simulation. The first version, released in September, has 350 million parameters and was trained on 250,000 3D simulations. Arena Physica says the field matters more as chips move to stacked 3D packaging and data links get faster.

The next versions will cover radiation patterns, more complex shapes and wider frequency ranges, for uses such as 5G and 6G antennas, satellite links, car radar and chip packaging. "Lux brings physics, AI, and compute together, enabling us to push the frontier of physics foundation models and train at a far larger scale than was possible before," said chief research officer Michael Frei. The release does not say how much compute time is involved.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
