GTC Spotlights NVIDIA RTX PCs and DGX Sparks Running Latest Open Models and AI Agents Locally

NVIDIA used GTC to showcase RTX PCs and DGX Spark for running local AI agents, and announced Nemotron 3 Nano 4B, Nemotron 3 Super 120B, and the open source NemoClaw stack. The post says DGX Spark has 128GB unified memory for models above 120B parameters; Nemotron 3 Super scored 85.6% on PinchBench, and Qwen 3.5 supports a 262,000-token context window. The key signal is local inference for privacy and zero token cost, while the full “latest open models” lineup and pricing are not disclosed in the post.

Why it matters: HKR-H/K/R all pass: the local-agent hook is strong, and the post includes concrete specs and benchmark numbers. I keep it in featured, not higher, because the full model list and pricing are not disclosed and the source is still a vendor launch post.
