Perplexity has made its agentic AI, which it calls Portable Computer, available to run directly on Windows PCs powered by AMD's Ryzen AI Max Series processors, including the Ryzen AI Halo developer platform. The pitch is that the heavy work happens on the device itself rather than in the cloud, so a professional can point an AI agent at sensitive files without those files leaving the machine.

Running the model on the laptop, not the cloud
On a Ryzen AI Max system, Perplexity says its setup runs large AI models on device, naming Qwen 3.8 27B and its own PPLX 27B. Running a 27-billion-parameter model locally means users can analyse sensitive documents and repeat recurring workflows without spending cloud credits on that local processing. When a task needs more, Perplexity says users can still reach out to cloud reasoning and web research.
A packaged local agent stack
Rather than asking users to assemble their own AI infrastructure, Perplexity bundles its local models, agent orchestration, scheduling and security controls together on Ryzen AI Max systems. It connects to Gmail, Outlook, Slack, GitHub and supported local applications, and adds folder-level permissions, sandboxing and enterprise IT controls so a company can decide what an agent is allowed to touch.
Who can get it, and when
Portable Computer on AMD Ryzen AI Max systems is available today through the Perplexity Windows app, for Pro and Max subscribers on both individual and enterprise plans. AMD set out the joint announcement in its newsroom.
The move fits a wider shift toward AI that runs on the machine in front of you. AMD itself recently debuted six Ryzen AI systems and a desk AI workstation, while agentic tools are arriving in mainstream software, from Microsoft's new Copilot building Word and Excel files by chat to government trials such as Malaysia's MyGOV testing agentic AI. What is new here is where the model sits: on the laptop's own silicon, for people whose files are the reason they cannot simply send everything to a server.
