Perplexity and Nvidia Launch Fully Local AI Agent With Zero Token Costs

Perplexity and Nvidia have launched Portable Computer, a local-first AI agent platform running on Nvidia-powered Linux hardware, specifically NVIDIA DGX Spark. This system integrates local models, a harness, and an OS-enforced sandbox to execute workflows directly on-device. Local tasks incur zero token costs and maintain data privacy by default, requiring user permission for cloud escalation. This strategic move indicates Nvidia's shift toward promoting local AI hardware as a practical tool beyond traditional data center solutions.
