JoulesPerBit Physical AI

Every inference.
Every joule.
Every machine.

The full physical AI stack. Microcontrollers to datacenter GPUs. Real-time inference, simulation, digital twins, fleet orchestration. Energy-metered at context-switch granularity.

The Problem

Robots don't know what anything costs.

Every robotics stack runs inference blind. No energy budgets, no per-task metering, no way to know if a 7B VLA model fits an edge device until it fails in the field.

The Stack

Six layers. One energy budget.

From the OS kernel to fleet-wide orchestration. Every layer speaks joules.

OS

pai-os

Physical AI Operating System

Capability-based microkernel. Hybrid scheduling: fixed-priority, EDF, round-robin. Energy budget enforcement at context-switch granularity. Kernel-scheduled inference. One API from MCU to SoC.

Edge AI

Heterogeneous Inference Runtime

17 compute backends. CPU, CUDA, Metal, Vulkan, wgpu, TPU, NPU, Hailo-8, ONNX, GGUF, TinyML, neuromorphic. Dispatch picks the right backend for the model shape, latency target, and energy budget. Q15 fixed-point on bare MCU.

Physics + Scenario Engine

Rigid-body physics, contact dynamics, sensor simulation, and scenario generation. 8 built-in scenarios from warehouse pick-and-place to outdoor navigation. Energy-metered per simulation step.

Digital Twin

Live Synchronization

Bi-directional sync between physical robots and their digital counterparts. State mirroring, drift detection, predictive maintenance alerts, and what-if scenario testing against the live twin.

Orchestration & OTA

Manage thousands of heterogeneous devices from a single pane. OTA model updates, rolling deployments, energy-aware task assignment, telemetry aggregation, and automatic rollback on anomaly detection.

Safety

Certification & Compliance

IEC 61508 SIL-3 and ISO 13849 PLd safety certification built into the runtime. Watchdog timers, safe-state fallback, emergency stop propagation, and continuous safety integrity monitoring.

IEC 61508 ISO 13849 SIL-3
Platform

One runtime. MCU to datacenter.

The same API runs on a $4 microcontroller and an NVIDIA Jetson Thor. Write once, deploy to any compute tier, and know the energy cost before it ships.

Heterogeneous Dispatch

Right Compute, Right Time

The scheduler knows every backend's power profile, latency envelope, and memory ceiling. It assigns each inference to the cheapest compute that meets the SLA. Automatic. At runtime.

VLA Quantization

7B Models on Edge

Per-layer mixed-precision quantization for vision-language-action models. Vision encoder at INT4, action head at FP16, language backbone at INT8. Sensitivity-aware. Action fidelity is never sacrificed for compression.

Federated Learning

Train Without Sharing Data

Federated averaging with differential privacy gradient perturbation and secure aggregation. Each robot improves the fleet model without sending raw sensor data to the cloud.

Cascade Inference

MCU First, Cloud Last

16-level deterministic cascade. Cheapest compute first. Only escalates when confidence drops below threshold. Most inferences never leave the device. You see the energy receipt for each level.

Energy-First

The only physical AI stack priced in joules.

Every inference, every sensor read, every motor command. Metered and receipted. Know the energy cost before deployment. Optimize after.

Architecture

From prototype to production.

Simulate in software. Test on hardware. Deploy to fleet. The energy budget follows the model through every stage.

Step 1
Simulate

Run scenarios in the physics engine. Measure energy per task.

Step 2
Quantize

Compress models to target hardware. Verify accuracy retention.

Step 3
Deploy

OTA push to fleet. Energy budgets enforced per device.

Pricing

Pay for compute. Not licenses.

No per-robot fees. No per-seat pricing. $5 minimum balance to start. Pay only for the energy your workloads consume. Every operation metered in joules.
