Perplexity has brought its Portable Computer agent to Windows, where it runs models locally on the device rather than in the cloud. The tool is a local variant of the company's Perplexity Computer agent, which decomposes and executes multi-step tasks on its own. NVIDIA RTX GPUs provide the acceleration, and keeping processing on the machine means sensitive data does not leave the PC.
Perplexity has begun using OpenAI's GPT-6 Astra to draft communications, modify software, and oversee production systems. The company says it now intervenes far less often than it did with previous models, indicating greater autonomy in day-to-day operations.
WHY IT MATTERS ↘Letting a frontier model touch production systems raises the governance question from 'is the output good?' to 'how do you detect failures the model never flags,' since declining human intervention can mean genuine reliability or simply fewer chances to catch silent errors. It also makes Perplexity an early operational reference for OpenAI's newest model, so reliability claims there will shape how competitors position agentic offerings on uptime and oversight cost rather than benchmark scores.
