Anima Anandkumar Advances AI for Physical Systems
Caltech professor Anima Anandkumar has led research applying AI to large-scale physical systems, notably developing FourCastNet — a neural forecasting model competitive with physics-based weather simulators — and advancing Neural Operators and the Fourier Neural Operator to model multi-scale physical phenomena. Her work demonstrates that building physical priors into neural architectures enables stable, efficient simulation and forecasting (including global weather via spherical harmonics), and shows promise in domains like fusion where small datasets can still yield fast, accurate predictions. The piece also notes related technical work such as TorchLean (integrating PyTorch-style networks with the Lean proof assistant) and Anandkumar’s appointment to the United Nations Scientific Advisory Board.
Research demonstrates a new, structure-driven route to large-scale physical simulation and forecasting (FourCastNet, Neural Operators) that could accelerate scientific modeling and simulation workflows; relevant to AI infrastructure and applications though not an immediate AdTech change.

Nvidia on Physical AI, Jetson, Simulation, and Agents
Nvidia VP and GM Deepu Talla discusses the company’s platform for physical AI and robotics, describing a three‑computer model: data‑center training (GB300, Vera Rubin), simulation (RTX Pro 6000, Omniverse) and edge runtime (Jetson Thor, Orin). Talla says roughly 2.5 million developers and over 10,000 companies build on Jetson today, while the industry ships about one to two million robots annually against an opportunity he pegs at tens of billions. Key themes include the rise of vision–language–action models and world models, the closed sim‑to‑real gap aided by Nvidia’s Omniverse and the open‑sourced Newton physics engine (with Disney Research and Google DeepMind), hybrid edge‑cloud architectures, agentic orchestration for fleets (Nvidia Mega blueprint), and the current industry focus on training and simulation before large‑scale edge deployment.
Import AI: Control Inversion, Intelligence per Watt, 100k+ GPUs
This Import AI issue highlights three major developments: a new paper by Anthony Aguirre (Future of Life Institute) called “Control Inversion” arguing that increasingly capable, autonomous AI will tend to absorb power from humans rather than grant it, raising hard safety and governance questions; a Stanford + Together AI research effort that proposes an “Intelligence per Watt” metric for measuring on-device model efficiency and coverage, finding local open-weight models now answer 88.7% of single-turn queries and accuracy-per-watt improved ~5.3× over two years; and Meta/Facebook’s publication of NCCLX, a heavily customized NCCL variant designed to run synchronized training on clusters exceeding 100,000 GPUs (claiming up to 12% per-step latency reduction on some Llama 4 runs). The newsletter notes continuing cloud capability and efficiency advantages, caveats about single-turn metrics, and broader implications for compute scale, on-device AI, and AI safety.
AI: From Inference Era to Orchestration Era
The article argues that as agentic AI systems mature, the performance bottleneck has shifted from model inference to orchestration — the CPU work between model steps (tool calls, state management, retrieval, result handling). It highlights NVIDIA's Vera CPU as hardware designed to accelerate agentic throughput rather than pure FLOPs, research demonstrating a 5B-parameter latent diffusion 'multiplayer interactive world model', and several platform and open-source developments: Rowboat (a local-first desktop AI coworker), Amazon Nova's Reverse DPO for selective unlearning, SenseNova‑Vision (multimodal unified vision generation), and MiniMax models landing on Amazon Bedrock. The piece frames these items as signals that infrastructure, apps, and research are converging on optimizing the orchestration layer of multi-step AI workflows.
