Microsoft has unveiled a new AI coding model designed to run on personal computers, along with security technology aimed at limiting autonomous agents’ unauthorized access to data. The company also demonstrated the Surface Laptop Ultra, equipped with Nvidia technology.
The announcements were made at a launch event in San Francisco on October 7. Microsoft CEO Satya Nadella and Nvidia CEO Jensen Huang attended the event.
The companies aim to run AI tools directly on personal computers, including coding assistants and applications that automate business processes. This approach could reduce reliance on cloud services.
Huang said the new technologies could change how software is developed, with programmers using AI more often to create applications, build models and develop software.
MXC will restrict agents’ activities
Microsoft’s Microsoft Execution Containers (MXC) system is designed to isolate AI agents in controlled environments and limit their access to files, networks and sensitive information.
Huang said MXC would allow organizations to specify exactly which data and resources agents can access. He said agents are kept in a “modifiable execution sandbox.”
According to Microsoft, the system records the actions of AI agents. This will allow security teams to monitor activity, investigate suspicious behavior and restrict access if necessary. However, how effective these protections will be in real-world conditions remains unclear.
The company said OpenAI and Anthropic would also use MXC to improve the security of their AI agents. The technology is designed to run on Windows, macOS and Linux, although Microsoft said it would offer deeper integration with Windows.
New laptop to offer 128 GB of memory
Microsoft calls its strategy of bringing AI capabilities from the cloud to personal computers “hybrid intelligence.” The approach combines devices’ processing power with cloud computing. Running models on a computer could reduce the need for an internet connection and allow some sensitive data to remain on the device. Lower cloud processing costs may also be an advantage, although the results depend on the hardware and the complexity of the model.
Nadella said users would expect AI capabilities to work seamlessly across local devices and the cloud. He said users would not need to distinguish whether a task was being performed on their device or in the cloud.
The Surface Laptop Ultra, designed for software developers and content creators, is equipped with Nvidia’s RTX Spark technology. The laptop offers up to 128 gigabytes of unified memory, a PixelSense touchscreen and one petaflop of AI processing power.
Microsoft said the device has 2.5 times the thermal capacity of competing laptops and weighs about 4.5 pounds — slightly more than two kilograms. The laptop also features Magnetic Connect, a magnetic USB-C charging system.
The Surface Laptop Ultra starts at $2,599, while the top configuration costs $5,899. Pre-orders are open, and systems equipped with RTX Spark are expected to begin shipping next week.
Microsoft also announced that Meta’s Muse AI model would be available on Windows. The Call of Duty video game is expected to come to RTX Spark systems in 2027.
The announcements are part of a broader shift toward running AI on personal computers. While the technology promises advantages in speed, privacy and cost, questions remain about the security and performance of increasingly autonomous AI systems.
