Perplexity and Nvidia unveil Portable Computer for local AI agent tasks on GPUs

Perplexity and Nvidia have released Portable Computer, a locally-run version of Perplexity's Computer AI platform that performs agentic workloads directly on a user's PC or workstation instead of relying on cloud servers. The app mirrors the original Computer interface, supports Qwen 3.8 and PPLX local models (both scaling to 27 billion parameters), and will soon add Nvidia's Nemotron 3.5 Lightning model, while asking users for permission before sending any data to cloud-based frontier models for harder tasks.

Perplexity debuts on-device AI agent 'Portable Computer' with NVIDIA

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.
