Today, we’re proud to unveil Heaviside-1, @arenaphysica's second generation foundation model for electromagnetism. Five months since announcing Heaviside-0, today’s launch marks a critical milestone towards building electromagnetic superintelligence, a foundational intelligence that understands EM across the spectrum and is capable of designing next gen electromagnetically-governed systems, from RF to semiconductors to photonics. Why we’re so excited about Heaviside-1, and what today’s announcement represents: > It’s big: Heaviside-1 is a GPT-2-size model, roughly 10x the size of Heaviside-0 and trained on 250k unique designs with >500B unique EM field samples > It’s fast: It generates predictions with 5 orders of magnitude acceleration relative to commercial solvers, with under 1dB of accuracy > Full-3D Encoding: Heaviside-1 natively encodes 3D structures, their material properties, and excitation patterns as input, a major step towards generalizability across design spaces > Understands the underlying physics primitive: Heaviside-1 generates full-3D near-fields at arbitrary locations, not just downstream quantities like s-parameters > Generalization: Most importantly, our bet on fields as the primitive for Heaviside-1 generalizes OOD, proving that it’s learning real EM physics. Heaviside-1 generalizes outside of distribution incredibly well and better than Heaviside-0, down to 0.53 dB s-parameter error from 0.99 dB on Heaviside-0.

Today, we're introducing @arenaphysica, the electromagnetic superintelligence company. Our mission: accelerate the design, development, and deployment of the devices that will sense, communicate, compute, and actuate in the future of autonomy, with EMSI. For years, we’ve been building a new type of company in the shadows with our partners and collaborators. We're proud to share that we’ve deploying EMSI with @AMD in AI compute, @anduriltech in defense technology, and @SiversSemicond in satellite and 5G communications. We've reached the Electromagnetic Inflection. software-defined hardware == electromagnetically-governed device Their behavior more attributable to Maxwell's equations than Newton's. A car's most expensive subsystem is its electronics. A datacenter's binding constraint is power delivery and SerDes interconnects. The F-35's avionics cost more than its engine. Electromagnetic design is a physics problem, and at @ArenaPhysica, we're building the stack to solve it. -> Atlas: an agentic platform deployed as the intelligence system of record for hardware workflows at companies building frontier devices, making probabilistic reasoning engines capable of deterministic engineering work. -> The EM Foundation Model: the first physics foundation model for electromagnetism, learning the relationship between geometry and fields directly to drive the time and cost of verification toward zero. -> The Electromagnetic IP Factory: vertical co-development of the most advanced electromagnetic IP in defense, automotive, compute, and communications alongside our most ambitious partners. I’m proud to be building this alongside @PratapRanade , @_clairepan , @m__frei , @hk2532_harish , and the rest of our artist colony here at @arenaphysica.
