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.
