GoKawiilPerplexity and Nvidia unveil Portable Computer for local AI agent tasks on GPUs
Perplexity and Nvidia have released Portable Computer, a locally-run version of Perplexity's Computer AI platform that performs agentic workloads directly on a user's PC or workstation instead of relying on cloud servers. The app mirrors the original Computer interface, supports Qwen 3.8 and PPLX local models (both scaling to 27 billion parameters), and will soon add Nvidia's Nemotron 3.5 Lightning model, while asking users for permission before sending any data to cloud-based frontier models for harder tasks.
GoKawiil's interpretation of the reporting above, not reported fact.
By shifting AI inference onto local hardware, Perplexity and Nvidia are addressing two major pain points for AI adoption: data privacy concerns and the recurring costs of cloud token usage. Nvidia's framing of local AI as reaching an 'inflection point' signals a broader industry push to make on-device AI agents mainstream rather than a niche for enthusiasts with powerful GPUs.
- Portable Computer runs Perplexity's agentic AI platform locally on Nvidia GPU-equipped PCs, avoiding cloud dependency.
- It supports Qwen 3.8 and PPLX 27B models now, with Nvidia's Nemotron 3.5 Lightning MoE model coming soon.
- Benchmarks show Portable Computer outperforming rivals like Pi and Hermes in local knowledge tasks, browsing, and document parsing.
NVIDIA GeForce RTX 5090 Founders Edition — Running Perplexity's Portable Computer locally means the heavy lifting happens on your own GPU, and NVIDIA's flagship GeForce RTX 5090 is built for exactly that kind of on-device AI inferencing. Its large VRAM pool and tensor cores let you keep bigger models and longer agent runs entirely off the cloud, with no token bills and no data leaving your desk.
