NVIDIA releases open Nemotron 3.5 Lightning for always-on agents
NVIDIA released Nemotron 3.5 Lightning, a 30-billion-parameter mixture-of-experts model with 3 billion active parameters, open weights, training data and recipes. The commercially usable model targets high-volume execution in long-running agents, runs on local hardware or data centers, and is distributed through open repositories, hosted APIs and cloud partners.
Why it moved the index
A permissively released, commercially deployable workhorse for always-on agents lowers cost and control barriers to persistent autonomous execution; magnitude 48 reflects meaningful diffusion below the capability frontier, while confidence 85 reflects dated primary launch and model-card evidence tempered by vendor-run performance claims.
