Perplexity and NVIDIA are bringing Portable Computer to Windows PCs, giving owners of compatible GeForce RTX and RTX PRO machines a local AI agent that can actually get things done. The catch is hardware: Windows support requires an NVIDIA GPU with 24GB or more of VRAM.
The idea is refreshingly simple. Portable Computer can plan and execute multi-step tasks on the PC, with NVIDIA GPUs accelerating the AI models behind it. That could mean reviewing GitHub pull requests, going through financial documents to find recurring fees, or analysing customer data and sending the findings to Slack. The important bit is that this work can happen locally.
This is where Portable Computer differs from the increasingly capable agents from OpenAI and Anthropic. ChatGPT Work can work with local files and desktop apps, while Claude Cowork can also operate across local files and connected services. But Portable Computer is designed around running its agent stack and models locally on supported NVIDIA hardware, rather than simply giving a cloud AI access to files sitting on a PC.
That doesn’t mean the cloud disappears. If a task needs web research or stronger frontier reasoning, Portable Computer asks for permission before sending the relevant content to a cloud service. So sensitive documents can stay on the machine while more demanding steps can be escalated when necessary.
Portable Computer is here on NVIDIA DGX Spark and Windows PCs, where the entire runtime can run locally, including the orchestrator and agent harness. That said, what’s most impressive is the timing.
NVIDIA says its new RTX Spark Windows PCs are arriving in October, bringing local AI to smaller systems beyond DGX Spark. Portable Computer therefore feels less like a one-off experiment and more like a preview of where NVIDIA wants RTX machines to go: not just computers that run AI, but computers that can actually do the work.
Did you think hitting delete on your AI chatbot conversation actually makes it disappear? Georgia Tech researchers just proved that's not entirely true. They have built a forensic tool called ORISA that can dig deleted conversations from your phone and even rebuild them into a working chatbot session you can keep talking to.
How can ORISA bring deleted AI conversations back?
Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind.
The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).
Two residents of Chicago have filed a lawsuit in the US over claims that robots run by Coco Robotics and Serve Robotics captured their facial and hand measurements without consent, bringing renewed attention to the food delivery robots. The cases raise a troubling question: If a robot delivers food to your door, can it also be gathering sensitive information about you?
According to a report by The Associated Press, the proposed class-action lawsuits were filed in Cook County on Oct. 9 and allege violations of Illinois’ Biometric Information Privacy Act. The complaints claim that the robots’ cameras and LiDAR sensors captured information on customers’ faces and hands as they approached the machines to pick up their orders. Both have denied the allegations.
