Perplexity has released Portable Computer, an agentic AI tool that runs entirely on local hardware instead of the cloud, built in partnership with NVIDIA. It relies on compact models like Qwen 3.8 and NVIDIA Nemotron 3.5 Lightning to handle complex tasks on-device, and only reaches out to cloud-based models when needed, with user permission. The feature is currently available to Perplexity Pro and Max subscribers running NVIDIA's DGX Spark hardware, with RTX GPU support planned.
Nvidia has updated Ray Reconstruction, its AI denoiser-upscaler for ray tracing, to the second-generation transformer architecture used in DLSS 4.5 Super Resolution. The company says the new model handles 35% more compute and 20% more parameters than before, improving image quality and reducing ray-tracing artifacts with little to no performance cost. GeForce RTX owners can access the update immediately.
Chris Malone, who led OpenAI's data center strategy after joining from Meta and Google in March 2024, has left the company. OpenAI confirmed it recently restructured its infrastructure organization, shifting oversight so that Malone no longer reported to President Greg Brockman but instead to VP Sachin Katti before his exit. The company says several other executives, including Uday Ruddarraju, Brent Mayo and Spas Lazarov, remain in charge of its data center efforts.
Elon Musk revealed on SpaceX's latest earnings call that the company's Starmind AI project will run on NVIDIA's Vera Rubin GPU architecture, both on the ground and eventually in orbit. Musk argued the NVL72 VR system design outperforms traditional rack-based computing setups and would be cheaper and more effective for SpaceX's needs.
Researchers identified a security bug in NVIDIA's OpenClaw tool that allows attackers to reach the local model server through the Ollama API without authentication. This unauthenticated access can be leveraged to tamper with the AI agent's underlying model, leading to persistent corruption of its outputs.
Perplexity and Nvidia have released an AI agent designed to run entirely on local hardware rather than through cloud-based inference, eliminating per-token usage charges. The system relies on on-device processing, letting users run agentic AI workflows without sending data to remote servers or paying ongoing API costs.
Reports indicate OpenAI and Google are both losing key AI researchers to competitors and startups, though the departures are affecting each company differently in terms of scale and strategic impact. Separately, Nvidia has committed an additional $6 billion to support open-weight AI models, while rare-book dealers report a surge in sales tied to AI-era demand, alongside mixed feelings about that trend.
On his CNBC Investing Club Morning Meeting, Jim Cramer discussed Apple's newly unveiled Mac Mini and Mac Studio, which feature upgraded chips for better AI performance. The new Mac Mini now starts at $899, a $100 increase reflecting higher memory and storage costs passed on to consumers.
Nvidia is gaining backing from more game studios for its RTX Spark technology and ARM-based chip architecture, signaling a shift toward wider hardware compatibility for PC gaming. This move could allow games to run more consistently across different laptop configurations, regardless of the underlying chip design.
OpenAI has revealed details of Jalapeño, a custom inference chip developed with Broadcom over roughly 16 months, at the Hot Chips conference. SemiAnalysis tested the chip using its InferenceX benchmark suite and found it outperforms Nvidia, AMD, and Google chips across multiple open-source models, despite being OpenAI's first hardware effort.
Perplexity has released Portable Computer, a version of its agentic 'Computer' platform designed to run entirely on local hardware, starting with Nvidia's DGX Spark desktop and Linux machines with RTX GPUs. The system keeps models, files, and processing on-device by default, only asking permission to route individual steps to cloud-based frontier models when needed, meaning local tasks incur no billing credits.
Nvidia announced that its GeForce Now cloud gaming service will support Valve's Steam Controller and Steam Machine later this year, initially for the Steam Deck and Steam Machine app, with Windows and macOS support coming afterward. The update accompanies other GeForce Now additions, including DLSS 4.5 controls, GOG single sign-on, wider Fire TV Stick availability, and Firefox browser support.
