Perplexity's New Agent Runs Entirely on Your GPU - with One Expensive Catch
The New Stack, Monday, September 14th, 2026
The New Stack covers Perplexity's Portable Computer on Windows, a local AI agent needing a 24GB+ RTX GPU.
The New Stack reviews Perplexity's release of Portable Computer for Windows PCs with NVIDIA RTX GPUs, the third operating system for a local AI agent harness that launched Linux-only in August.
The release adds local MCP connections and scheduled tasks, letting the agent handle multistep work such as analysing files and running recurring workflows on-device.
Sensitive data stays on the machine, with heavier tasks optionally handed to cloud models on user permission.
The catch the article highlights is the hardware floor: GeForce RTX or RTX PRO cards with 24GB or more of VRAM, plus a paid subscription, putting it out of reach of mainstream laptops.
