NVIDIA family of language models, including a 74B mixture-of-experts model for local agents and a small model for game characters.
Nvidia launched RTX Spark laptops on Friday with up to 128GB of shared memory and a 74-billion-parameter model it says fits in 24GB. A local agent pilot is now possible on Windows, though every figure so far comes from Nvidia.

NVIDIA says its Nemotron 3.5 Bolt 74B-A9B agent model fits in 24GB and will ship with open weights, data and recipes. The footprint, the license terms and the quality claims stay unverified until the weights are live and outside testers have run them.
