Perplexity AI launched Portable Computer, an on-device AI agent for Nvidia-based desktops.
It automates multi-step tasks like web development using local language models.
The launch follows reports of potential Nvidia investment and licensing talks.
What happened
Perplexity AI Inc. today introduced Portable Computer, an on-device AI agent for desktops with Nvidia silicon, such as the DGX Spark. It runs on the open-source Qwen 3.8 27B model or Perplexity's optimized PPLX 27B, and includes a context compaction feature to handle long prompts.
Why it matters
This follows reports that Nvidia may invest in Perplexity at a valuation over $30 billion and has floated licensing its technology. The launch extends Perplexity's multi-step task automation to local hardware, potentially reducing reliance on cloud processing.
What to watch
An upcoming update will expand support to Windows PCs with Nvidia RTX graphics cards and add Nvidia's Nemotron 3.5 Lightning model. Perplexity also plans to let the agent request cloud help when the on-device model struggles.

The launch of Portable Computer is a strategic move for Perplexity, aligning with reported talks of Nvidia investing at a valuation over $30 billion and potentially licensing its technology. By bringing its cloud-based Perplexity Computer agent on-device, Perplexity aims to offer similar multi-step task automation with local processing, which could appeal to users prioritizing data privacy or low latency. The integration with Nvidia's DGX Spark and future support for RTX Windows PCs suggests a deepening partnership with Nvidia, while the ability to offload tasks to the cloud when needed provides a fallback for complex operations. Perplexity's focus on guardrails, such as sandboxing and permission controls, indicates an effort to address security concerns in on-device AI. The planned addition of Nvidia's Nemotron 3.5 Lightning model further underscores this collaboration, potentially enhancing performance on devices with limited processing power.
