Canvas 7 — Inference Optimization & Serving for Physical AI in Heavy Industry

Nov 11, 2026

How to use this canvas

This canvas covers the path from a trained model to fast, efficient and monitored inference for physical-AI platforms in heavy industry (construction, mining and earth-moving autonomy): on machines (for example NVIDIA Jetson Thor-class computers) and in the cloud (NIM, Dynamo-Triton, TensorRT). It is canvas 7 of 9 and follows a research-area exploration framework, with the Emerging (11–12) and Applied (13) modules added.

Boundary Owned here Owned elsewhere
Training Feeding latency and hardware limits back to training Model design and training (canvas 3)
Evaluation Producing the optimized engine that gates must test Gate design and running (canvas 4)
Lifecycle Building engines from registered models; runtime monitoring hooks Registry, OTA rollout, rollback (canvas 5)

SLOs and cost Measuring latency, throughput and cost per inference Setting standards and targets (canvas 8)

1. Core definition and scope

Definition. Inference optimization turns a trained model into an engine that meets latency, throughput, memory and power targets on specific hardware, without losing required accuracy. Serving runs that engine reliably for its consumers: a control loop on a machine, or an API in the cloud. For robots, the job is not just running a model but running it alongside perception, control and planning stacks that already load the GPU and CPU (NVIDIA).

path to optimized inference · 6 stages owned here

One compiled, gated engine goes either to the machine or to the cloud; both report the same health signals back to monitoring.

Two very different targets

On-machine (edge) Cloud
Hardware NVIDIA Jetson Thor (T5000, T4000) as the reference platform in this canvas Datacenter GPUs in owned clusters or GPU clouds
Main limit Latency per control step, power, memory, safety timing Throughput and cost per request at a latency target
Typical models Perception, VLA policies, in-cab operator assistant Assistant back-ends, teacher models, auto-labeling, evaluation
Runtime TensorRT, TensorRT Edge-LLM, Holoscan / ROS 2 NIM, Dynamo-Triton, TensorRT-LLM, vLLM

Key sub-domains

Sub-domain Core question Typical artifacts
Export and compilation Can the model be compiled for the target? ONNX exports per component; TensorRT engines
Quantization How low can precision go without hurting results? FP8, NVFP4, INT8 calibration sets and reports
Architecture-level speedups Fewer denoising steps, smaller heads, distillation Distilled students; step-reduced policies
Real-time execution How do actions stay smooth despite inference delay? Action chunking, asynchronous execution
On-machine scheduling How do several models share one Thor? MIG partitions, CUDA streams, priorities
Cloud serving How do we serve many requests cheaply? NIM containers, Dynamo routing, autoscaling
Runtime monitoring Is inference healthy and in-distribution? Latency, OOD scores, confidence telemetry

Debate. Optimize the model (quantize, distill) or buy more hardware? On machines, hardware is typically fixed for years, so model optimization is usually necessary; in the cloud it is a cost trade-off.

2. Historical context and evolution

Inference moved from compiling vision CNNs to INT8, to serving LLMs at scale, to running multi-billion-parameter VLAs at control rates on embedded GPUs.

Year Milestone Why it matters here
2026 GR00T N1.7 on Jetson Thor with mixed NVFP4: 125 ms → 39.9 ms end to end, 25 Hz, no measurable task loss (Jetson AI Lab) A 3B VLA runs at control rate on the machine
2026 Jetson T4000 and JetPack 7.1 with TensorRT Edge-LLM (January) (NVIDIA); Dynamo 1.0 Production LLM/VLM runtime at the edge; stable distributed serving in the cloud
2025 Jetson AGX Thor GA (August); NVIDIA Dynamo announced (GTC) as successor to Triton; real-time chunking for VLAs (NeurIPS 2025) FP4 at the edge; disaggregated serving; smooth asynchronous control
2024 NIM microservices; FP8 serving mainstream on Hopper Packaged, optimized model containers
2023 TensorRT-LLM; vLLM (PagedAttention) LLM-specific serving optimizations
2018–2021 Triton Inference Server; Jetson Xavier and Orin; INT8 quantization-aware training Multi-framework serving; edge AI on machines
2016–2017 TensorRT 1.0; Jetson TX1/TX2 Compiled, optimized inference on NVIDIA GPUs

Paradigm shifts

  1. From INT8 to FP8 and FP4. Blackwell's Transformer Engine switches between FP4 and FP8 at runtime on Thor (Edge AI Stack).

  2. From one model per device to many models per device. Thor runs perception, VLA, speech and assistant models side by side, partitioned by MIG.

  3. From synchronous to asynchronous control. Real-time chunking generates the next action chunk while the current one executes, with no retraining.

  4. From monolithic to disaggregated serving. Cloud LLM serving splits prefill and decode across GPUs (NVIDIA).

3. Current state of research

On the machine, the question is whether a multi-billion-parameter policy can run at control rate next to everything else without losing behavior quality. In the cloud, it is cost per request at a latency target. Both are now solvable; neither is automatic.

Dominant frameworks

Key research questions

Question State of evidence
Does low-bit quantization hurt closed-loop behavior? Yes if done naively: small action errors compound in closed loop (QVLA, ICLR 2026); PTQ can cause kinematic drift (DA-PTQ)
Can action-aware quantization fix that? Channel-wise, action-sensitivity-based bit allocation (QVLA), drift-aware PTQ and mixed precision (Mix-QVLA) recover most performance
Is smoothness enough, or does reaction time matter? Asynchronous methods improve smoothness but can neglect reaction latency to sudden changes (FASTER, arXiv 2603.19199)
How do several models share one Thor? MIG partitions and priorities; little published for safety-critical mixes
How cheap can cloud LLM serving get? GB300 + Dynamo + TensorRT-LLM report 35x lower cost per token than Hopper (NVIDIA reference architecture)

Challenges for heavy equipment

Debates

4. Key stakeholders and research centers

Industry peers Komatsu (NVIDIA partnership), Aurora (NVIDIA DRIVE Thor), Bedrock Robotics (see the evidence block below) Public precedents for on-vehicle AI

Inside heavy-equipment OEMs and autonomy developers (public evidence). The public record on on-machine inference is thinner than for cloud serving. What can be cited:

Takeaway: public evidence on bounded latency, quantization and mixed-criticality sharing for heavy machines is mostly absent, which is why those appear as gaps in section 7.

Debate. Should a heavy-equipment platform standardize on NVIDIA's runtime end to end, or keep a portable path in case of hardware change over a 10–20-year machine life (a long-life assumption, not a measured figure)?

5. Methodological landscape

Methods group by optimization step. Each has a default and a frontier.

6. Interdisciplinary connections

Inference is where training meets the machine. Each interface needs a contract.

Connects to What crosses the boundary Contract to define
Canvas 1: data flywheel On-machine triggers and confidence signals that select data to upload Trigger API and telemetry schema
Canvas 2: simulation Hardware-in-the-loop and software-in-the-loop testing of exact engines Same engine and runtime version in simulation and on the machine
Canvas 3: training Latency, memory and precision budgets per target Budgets agreed before training starts
Canvas 4: evaluation Optimized engines for gate testing Gates always run on the shipped engine
Canvas 5: MLOps Engines registered and linked to source models; OTA packages Engine build is a registered, reproducible step
Canvas 6: infrastructure Cloud serving capacity, MIG, autoscaling Inference node pools and quotas
Canvas 8: observability Latency, throughput, cost, thermal metrics Shared metric names; SLOs per service

Outside fields

7. Future directions

The frontier is co-design: models trained for the precision, step count and latency the machine can afford, with behavior-preserving compression checked in closed loop.

Emerging trends

  1. FP4 at the edge. NVFP4 on Thor makes 3B-parameter VLAs practical at 25 Hz (Jetson AI Lab).

  2. Action-aware compression. Quantization judged by action error and closed-loop success, not perplexity.

  3. Reactive asynchronous control. Methods that keep motion smooth and also react quickly to sudden changes.

  4. Speculative decoding on the edge. Large speedups for assistant LLMs on Thor (NVIDIA).

  5. Unified cloud serving. Dynamo absorbs Triton; NIM packages models with optimized engines.

  6. Smaller modules. Jetson T4000 brings 1,200 FP4 TFLOPS and 64 GB in a 40–70 W envelope (NVIDIA), opening lower-cost machines.

Research gaps in heavy-industry physical AI

Gap Why it is open Opportunity
Bounded latency for learned policies Average-latency benchmarks dominate Worst-case timing analysis for VLA pipelines under load and heat
Mixed-criticality sharing of Thor Little published work on safety and non-safety models on one GPU (a literature-search impression, not a systematic review) Partitioning patterns (MIG, priorities) qualified with safety engineering
Quantization effects on hydraulic control Studies use arms and simulators Closed-loop quantization tests on excavator policies
Long-life runtime support Engines tied to JetPack and hardware versions Rebuild-and-requalify pipeline per platform release

10. Practical applications

One machine computer will run several model families with different timing needs. A starting allocation for a Thor-class machine computer in construction or mining equipment (illustrative, not drawn from any named deployment):

Workload on the machine Criticality Latency need Precision approach Runtime
Person and obstacle detection Safety-related Tight, bounded per frame FP8 or FP16; quantize only with full regression TensorRT, own MIG partition
Autonomy policy (VLA or imitation) Safety-related behind certified limits Control rate, e.g. 25 Hz with action chunks Mixed NVFP4/FP8 with closed-loop checks TensorRT engines + real-time chunking
In-cab operator assistant (speech + compact LLM) Non-safety Conversational, around a second Aggressive (FP4/INT4) acceptable TensorRT Edge-LLM or vLLM
Data triggers and telemetry models Non-safety Seconds Aggressive TensorRT
Cloud: assistant back-ends, auto-labeling, teachers Non-safety Throughput at latency target FP8 / NVFP4 NIM, Dynamo-Triton, TensorRT-LLM

Figures are illustrative; set real budgets with controls and safety engineering.

Field-level application areas

Application Inference demand Public evidence
Construction autonomy (excavators, earthwork) Perception, planning and control on the machine at control rate; stop-on-proximity safety behavior Bedrock Robotics deployments on three sites (BD+C)
Mining haulage Fleet-scale autonomy with on-truck perception and control plus site-level dispatch Rio Tinto and Komatsu autonomous haulage (AL Circle)
In-cab and operator assistance Cab cameras and speech or LLM models on the machine computer; non-safety latency targets Komatsu and NVIDIA cab-camera plans (Equipment World)
Jobsite digital twins and cloud analytics Batch and interactive cloud inference for mapping, progress tracking and simulation; cost per request matters Cloud serving stack: Dynamo, NIM (see section 3); no heavy-industry-specific benchmark found
Autonomous trucking (adjacent) Primary plus independent secondary compute for failure takeover Aurora, Continental and NVIDIA (Business Wire)

Industry connections

Future applications (speculative): lower-cost autonomy kits using Jetson T4000-class modules for smaller machines; retrofit kits for existing fleets.

11–12. Technology integration, ethics and regulation

Technology integration

Ethical considerations

Regulatory requirements

Rule What it means for inference
EU Machinery Regulation 2023/1230 (from 20 January 2027) Software and AI performing safety functions are safety components; the deployed engine is what is assessed. AI-specific requirements may follow via delegated or implementing acts (see canvas 5)
ISO 13849 / IEC 62061; ISO 17757 Timing and fault-handling requirements for safety functions; learned components need a safe architecture and monitoring
Cybersecurity (EU Cyber Resilience Act, Machinery Regulation essential requirements) Signed engines, secure boot, protection against tampering with models on the machine
Privacy (GDPR and local laws) In-cab audio and video handling for operator assistants

Implication: optimization changes behavior, so each optimized engine is a new artifact that must pass gates, not a free speedup.

13. Implementation framework

Build in four phases. Start with a reproducible engine pipeline and latency budgets; push precision lower only with closed-loop evidence.

Four-phase inference rollout roadmap
Figure 2. Rollout: engine pipeline → closed-loop gates → lower precision → shared machine.

inference rollout · 4 phases, 3 gates

Phases are sequenced, not dated. Phase 1 is highlighted because every later speedup must be measured against a reproducible baseline engine.
