Testing Nemotron's 3.5 Lightning's 1M-Token Context on the DGX Spark
2026/08/17
NVIDIA just shipped a model with four times the context window of what's been running my home agent for months. So I swapped it in, broke my own setup within the first hour, and then threw 700,000 words at it to see if it would lie to me.
No guest this episode, just me and my home lab. Jarvis, my home agent, has been running on Qwen3.6-35B-A3B since the start, served through vLLM on the DGX Spark's 128GB of unified memory. Then NVIDIA released Nemotron 3.5 Lightning 30B-A3B in NVFP4, and one number stopped me mid-scroll: a validated 1 million token context window, four times what Qwen gives you at 262,000.I don't trust a spec sheet claim until I've broken it myself, so I swapped the model into Jarvis, found a memory reservation bug in NVIDIA's own deployment recipe within the first hour, fixed it, and then buried a fabricated secret code word 90% of the way through a 700,000 word document to see if the model could actually recall it. I also dug into DSpark, the speculative decoding checkpoint built specifically for this hardware, and measured what it actually does for throughput.
This episode is the honest version: what's proven on my own hardware, what's still sitting on NVIDIA's spec sheet, and what I still don't know about whether Nemotron makes Jarvis a better agent day to day.
Key topics covered:
Why Jarvis's setup (Qwen3.6-35B-A3B on vLLM) needed an indirection layer before any of this matteredNVIDIA Nemotron 3.5 Lightning 30B-A3B-NVFP4's validated 1 million token context window, tested against a 700,000-word documentThe memory reservation bug in NVIDIA's DGX Spark deployment recipe, and the one-line fixDSpark speculative decoding: how it works, and the acceptance rate that made it worth usingNemotron's hybrid Mamba-2, attention, and mixture-of-experts architecture, and why it matters for running 1M tokens on a single boxWhat's proven on real hardware versus what's still just NVIDIA's own benchmark numbersWhy Nemotron isn't confirmed as the better agent brain for Jarvis yet

017 - SUSE AI Factory with NVIDIA Explained
2026/06/30
Most enterprise AI projects succeed as pilots. They fail on the way to production. In this episode, Rhys Oxenham, VP and General Manager of AI at SUSE, joins me to break down what SUSE announced at SUSECon 2026: SUSE AI Factory with NVIDIA.
We go deep on what it actually is, what problem it solves, and what happens when AI starts managing the infrastructure itself. We cover the assembly line concept, validated blueprints, why this isn't just for large enterprises, unified support across the full stack, digital sovereignty as resilience, and the very real governance challenge when agents start acting autonomously in your cluster, what I've been calling "YOLO ops." Release is July 2026. This is worth understanding before then.

016 - Nemotron 3 Ultra: NVIDIA’s Open-Weights Frontier Agent Brain (1M Context, 5x Faster)
2026/06/12
Johan breaks down NVIDIA’s ComputeEx 2026 announcement of Nemotron 3 Ultra 550B-A 55B, an open-weights mixture-of-experts model with 550B total parameters and 55B active, positioned as an orchestration “agent brain” for multi-step tasks behind the firewall. He reviews NVIDIA’s benchmarks versus GLM 5.1, Kimi K 2.6, and Qwen 3.5, highlighting best-in-class instruction following (82%), long-context performance (95%) with a 1M-token window, strong agent productivity (91%), and weaker coding results on TerminalBench versus Kimi. Johan emphasizes reported advantages in speed (~300 tokens/sec, ~5x faster), cost (up to ~30% cheaper on SWE-bench tests), and deployability via a unified NVFP4 checkpoint optimized for H100 and B200 GPUs, plus NemoClaw as the agent blueprint. He closes with an early-access demo comparing two agents researching Netherlands’ 2026 World Cup odds, showing Nemotron’s more granular path analysis and a 5.8% win estimate.00:00 Private AI Lab Intro01:19 Nemotron Ultra Explained02:22 Agent Brain Focus03:07 Benchmark Reality Check05:14 Speed And Cost Edge06:11 Training And Precision08:02 NeMo Claw Agents08:58 World Cup Agent Demo12:22 Why This Matters13:17 Wrap Up And Links
015 - Meet Sparky: A Real-Life Jarvis with Alexis Gallagher
2026/05/13
I've been trying to build my own Jarvis for years. Then I met Alexis Gallagher at GTC — and Sparky is the closest thing I've seen.
Alexis is an AI researcher and developer, formerly at Answer AI and Google, now building something most people in AI aren't: a robot designed not just to be useful, but to be *alive*. Sparky lives on his desk in San Francisco. He initiates conversations. He develops his own evolving interests — eels, catenary arches, abandoned infrastructure. He knows who's in the room, when to speak, and when to stay quiet. And he noticed when it was Alexis's first Friday after leaving his job.
In this episode we go deep on the two design goals behind Sparky (useful and alive), the OpenClaw orchestration layer, the social awareness architecture running five times per second, the shared workspace principle that unlocks genuinely useful AI at a desk, and the tradeoffs between cascading and voice-to-voice architectures. We also do a live model switch mid-episode — from Claude Sonnet 4.6 to Nemotron 3 Super 120B running locally on a DGX Spark. It goes impressively well. Until it doesn't. That's in there too.

014 - Project Q9: Where Robotics and AI meet (with Sander Harrewijnen)
2026/04/30
In this episode, Johan is joined by long-time colleague Sander Hardewijnen to pull back the curtain on Project Q9 — an ambitious internal project at ITQ that combines a Unitree Go 2 Pro robotic dog, private AI, computer vision, and modern cloud-native development practices.
From gesture recognition trained on 30,000 hand images to a Skynet-obsessed dog posting on LinkedIn, this episode is a deep dive into what happens when you give great engineers a suitcase full of robot and say, "see where it goes."
The conversation also covers the state of open-source AI coding assistants (OpenClaw vs NemoClaw), the realities of vibe coding in a production context, and what partner platforms like Red Hat OpenShift AI and SUSE AI actually enable beyond conversational AI.

#007 - From Zero to Agentic AI — All Before Your Coffee Gets Cold (with Tasha Drew)
2026/02/05
What if deploying private, enterprise-grade AI didn’t take months—but only as long as it takes your coffee to cool?
In this episode of The Private AI Lab, Johan van Amersfoort sits down with Tasha Drew to unpack how Private AI Services on VMware Cloud Foundation are changing the way enterprises build and consume AI.
They discuss why AI needs a platform layer, how Broadcom integrates open source responsibly, what MCP means for enterprise AI, and how agentic AI workloads can be deployed securely, governed properly, and operated at scale—inside the private cloud.

#006 - The Subtle Art of Inference with Adam Grzywaczewski
2026/01/22
In this episode of The Private AI Lab, Johan van Amersfoort speaks with Adam Grzywaczewski, a senior Deep Learning Data Scientist at NVIDIA, about the rapidly evolving world of AI inference.
They explore how inference has shifted from simple, single-GPU execution to highly distributed, latency-sensitive systems powering today’s large language models. Adam explains the real bottlenecks teams face, why software optimization and hardware innovation must move together, and how NVIDIA’s inference stack—from TensorRT-LLM to Dynamo—enables scalable, cost-efficient deployments.
The conversation also covers quantization, pruning, mixture-of-experts models, AI factories, and why inference optimization is becoming one of the most critical skills in modern AI engineering.
Topics covered
Why inference is now harder than training
Autoregressive models and KV-cache challenges
Mixture-of-experts architectures
NVIDIA Dynamo and TensorRT-LLM
Hardware vs software optimization

In this episode of The Private AI Lab, Johan van Amersfoort talks with Maxime Colomès about the Model Context Protocol (MCP)—one of the most important emerging standards in AI today.
MCP is often described as the USB-C of AI: a universal way for AI models to connect to tools, data sources, and real-world systems. Maxime explains what MCP is, how it works, and why its recent donation to the Linux Foundation is such a major milestone for the AI ecosystem.
They explore real-world enterprise use cases, MCP security considerations, private AI architectures, and how MCP integrates with platforms like OpenShift AI. The conversation also touches on developer productivity, AI agents that can take action, and the future of personal, privacy-preserving AI assistants.
