Perplexity, Nvidia Run Chinese AI Model Locally on the “Portable Computer”

OpenClaw sends its regards: the AI startup Perplexity has just introduced “Portable Computer,” a version of its agent product Perplexity Computer that runs entirely on the user’s own machine. It was built together with Nvidia. The announcement comes at the same time as reports that Nvidia wants to buy into Perplexity at a valuation of more than 30 billion dollars.

Where the Local AI Runs

Portable Computer is available first for the NVIDIA DGX Spark, Nvidia’s desktop-sized AI computer. It is built around the Grace Blackwell GB10 platform with a 20-core Arm CPU and 128 GB of unified memory. A version for PCs with RTX GPUs is set to follow. The first release runs on Linux, with Windows support announced. Access is limited to Pro and Max subscribers, and installation happens through a one-click setup inside the app, according to Perplexity.

The device runs the models along with the entire machinery around them: orchestrator, planner, tool router, scheduler, the task queue and the local search index. As long as the work stays local, it costs no credits, which is meant to make high-volume routine tasks more attractive economically.

Which Models Are in Play

The local model options are Qwen 3.8 27B and PPLX 27B, a version of the Qwen model that Perplexity has post-trained. That post-training aims to complete as much of a task as possible on the device and to move to the cloud only when the task requires it. NVIDIA…
