Nvidia and Microsoft push AI agents onto Windows PCs

Nvidia and Microsoft announced RTX Spark, a new chip and Windows PC platform built for personal AI agents that can run work locally instead of sending every task to the cloud.

The first RTX Spark laptops and small desktops are planned for this fall from Microsoft Surface, ASUS, Dell, HP, Lenovo, MSI, Acer, and GIGABYTE.

Today's lineup

  • Nvidia RTX Spark brings local agent compute to slim Windows laptops and small desktops.
  • Microsoft is adding Windows platform work for agent security, containment, scheduling, and local AI performance.
  • Nvidia also announced DGX Station for Windows, a much larger deskside agent system for enterprise teams.
  • GitHub Copilot's AI Credits billing starts today, making heavy agent usage easier to meter.

Nvidia | RTX Spark makes the AI PC more serious

RTX Spark combines an Nvidia Blackwell RTX GPU, a 20-core Grace CPU, up to 1 petaflop of FP4 AI performance, and up to 128GB of unified memory in a Windows PC chip.

Nvidia says the new PCs are built for local agents, creative work, AI development, and gaming. The company says RTX Spark can run 120-billion-parameter language models locally with up to 1 million tokens of context, while also supporting heavy video, 3D, and gaming workloads.

The important shift for normal users is where the work happens. A local agent can search files, handle private context, and run repeated tasks on the machine itself when the app and policy setup allow it. Cloud models still matter, but the PC is being positioned as part of the AI stack again.

Microsoft | Windows gets ready for local agents

Microsoft says RTX Spark PCs will join the Copilot+ PC category and that Windows has been optimized for the new Nvidia hardware, including workload scheduling, power management, unified memory support, Windows ML, and Prism emulation for x86 apps on Arm.

The more consequential part is security. Nvidia says the companies are working on Windows security primitives and Nvidia OpenShell so agents can run under identity, containment, policy, and privacy controls.

That matters because local agents are only useful if users can limit what they can touch. File access, app access, budget, and cloud handoff need to become visible controls, not hidden magic.

Nvidia | DGX Station comes to Windows

Nvidia also announced DGX Station for Windows, a deskside AI supercomputer built on the GB300 Grace Blackwell Ultra Desktop Superchip and planned for Q4.

This is not a home PC. Nvidia is aiming it at enterprise developers, researchers, engineers, designers, and data scientists who want to build and run agents on Windows workflows while keeping heavier models local.

Nvidia says DGX Station for Windows can run models of up to 1 trillion parameters locally and can support hundreds of agents executing tasks at the same time. For most readers, the takeaway is simple: the same local-agent idea is now being pushed at both laptop and enterprise workstation scale.

GitHub | Copilot credits start today

GitHub Copilot's usage-based billing change goes live today. Premium request units are being replaced by GitHub AI Credits, and usage is calculated from token consumption across input, output, and cached tokens.

Seat prices are not changing, according to GitHub, and code completions plus Next Edit suggestions remain included in paid plans. The bigger change is for agentic work: long coding sessions, reviews, and model-heavy runs now have a clearer meter.

This is the software side of the same story. Agents are becoming more powerful, but the cost of running them is becoming more visible.

Why it matters now

The AI story is moving from model launches to execution surfaces. A year ago, the big question was which chatbot answered better. Now the fight is over where agents run, what they can touch, how much they cost, and how safely they can act.

Local AI PCs will not replace cloud AI. They can change the default for private files, long context, media work, and repeated tasks that are awkward or expensive to push through a remote model every time.

SMB Monday: plan one local-agent workflow

Do not buy around this announcement yet. The first RTX Spark PCs are not expected until fall, and prices will decide how practical they are for small teams.

But this is a good week to pick one workflow that would benefit from local AI. Start with work that repeats often and touches sensitive context: searching old client files, drafting from internal notes, organizing media assets, preparing reports from local folders, or summarizing documents that should not be sprayed across random tools.

Write down the app, the files it needs, what the agent should never touch, and what a human must approve before anything gets sent or changed. That list will matter more than the chip name when local agents become easier to buy.

What to watch next

Microsoft Build starts tomorrow, June 2, and Nvidia says more Windows agent capability details are coming there. Watch for the boring parts: permission prompts, admin policy, app support, and whether normal users can understand what an agent is allowed to do.

Also watch OpenAI's ChatGPT model menu. OpenAI's latest release notes say GPT-4.5 retires from ChatGPT on June 27 and o3 retires on August 26. The practical pattern is clear: older favorite models are giving way to newer default systems, so teams should document any workflow that depends on one specific model.
