Nemotron Labs 3 Elastic

NVIDIAOpen WeightsPending Human Review

Nemotron Labs 3 Elastic is an open-weight NVIDIA language-model release. Star Elastic packages several nested reasoning models in a single checkpoint derived from Nemotron 3 Nano. Importance-based component ranking and elastic post-training let developers extract smaller subnetworks without independently training each size. The 23B and 12B variants share the larger checkpoint’s parameter space. The license permits commercial and non-commercial use subject to its published terms.
