Perplexity is bringing its agentic desktop client to Windows. The company said its Portable Computer — an application that runs multi-step agent tasks on-device — is now available on Windows PCs with NVIDIA GeForce RTX or RTX PRO GPUs, using a locally optimised Qwen 3.8 27B model so users can keep sensitive documents off the cloud and stop burning agent credits on routine work.
Local Model, Windows Stack
Portable Computer targets machines with 24 GB or more of VRAM — a class that now includes RTX 5090 desktops and RTX PRO workstations — and post-trains Qwen 3.8 27B for NVIDIA CUDA execution. The client analyses local documents and connects to productivity apps including Outlook, OneDrive, Word, Gmail, Slack and GitHub, escalating to cloud models only when a task needs a bigger context or specialised skill.
NVIDIA's Local-First Pitch
For NVIDIA, the launch reinforces its argument that RTX-class silicon can host agentic AI locally, complementing its cloud-native DSX-powered AI factory expansion and its recent investment in Perplexity. The Windows debut expands the platform from the Mac release Perplexity shipped in early September.
Why It Matters
Agent workloads have moved beyond chat: enterprise users want an assistant that can open a spreadsheet, edit a Word doc and file a JIRA ticket without shipping their data through a third party. Perplexity Portable Computer is one of the first commercial agentic clients tuned to run at Qwen 3.8 27B scale on a consumer-grade RTX GPU, and it puts Microsoft, Perplexity and NVIDIA on the same side of a shifting front — local, task-completing assistants that neither Anthropic nor OpenAI ships natively today.
