Nvidia releases Nemotron 3.5 Lightning 30B open-weight model for agentic workloads

Nvidia introduced Nemotron 3.5 Lightning, a 30-billion-parameter open-weight model designed for high-volume agentic workloads. It uses a mixture-of-experts architecture with only about 3 billion parameters active per token. Nvidia reported strong results on agentic benchmarks and claimed higher output speed than similarly sized models. The release forms part of a broader industry push toward open-weight models for specialized and agentic tasks.
