NVIDIA said RTX Spark laptops, which combine a Blackwell RTX GPU and a Grace CPU in a single superchip, are now sold by ASUS, Dell, HP, Lenovo, Microsoft and MSI. The systems offer up to 128GB of unified memory and up to 1 petaflop of FP4 AI performance.

Nemotron 3.5 Transcribe

NVIDIA's new open-weight speech model transcribes recorded conversations, labels speakers and translates. It supports 40 languages and can handle all three tasks with a single prompt. It is available on Hugging Face in BF16, FP8 and NVFP4 formats.

A new feature in NVIDIA App lets users choose how GPU resources are shared between foreground apps and background AI agents. It requires hardware-accelerated GPU scheduling to be enabled in Windows Settings.

Liquid AI's LFM3 family, which spans text, vision, audio and decision models on one shared backbone, gets day-zero support on RTX Spark. According to the company, its new 1.7-billion-parameter base model outperforms its previous 2.6-billion-parameter model.
