Nvidia CEO Jensen Huang is on stage at Microsoft Build this morning, albeit virtually. He says Nvidia started working with Microsoft on RTX Spark about three years ago, and it has led to the creation of the new Surface Laptop Ultra and Surface RTX Spark Dev Box.

Microsoft just launched a new Surface Dev Box, and the company is already using the machine live on stage at Build. The top looks like the vent on an Xbox Series X, and inside there’s an Nvidia RTX Spark chip and 128GB of unified memory. Overall, I’d say it looks like a flattened Xbox Series X.

Microsoft CEO Satya Nadella has started his Build developer keynote by focusing on Windows immediately. Microsoft is expanding Windows AI APIs to more PCs, through CPU, GPU, and NPU support. There are two new local AI Windows models too, Aion 1.0 Instruct and Aion 1.0 Plan.

Microsoft is kicking off its Build developer conference today with a promise of making Windows a trusted platform for development. As the company continues to focus on performance and reliability fixes for Windows 11, it’s also creating a developer-optimized experience that bundles a lot of useful tools and apps and embraces Linux even further.
