NVIDIA Nemotron 3.5 Lightning is now live on OpenRouter. A 30B hybrid MoE with 3B active params, distilled from Nemotron 3 Ultra. Built for high-volume, specialized AI agent workloads, delivering up to 4× higher throughput and up to 30% faster task completion compared to similar models in its class. https://t.co/7IUCTL4JYw
Context
NVIDIA's Nemotron 3.5 Lightning is described as built for high-volume, specialized AI- workloads. Its 30 billion parameters are the model's total learned values; only about 3 billion are active per forward pass, according to NVIDIA's technical specifications, which describe a design that uses selected parts of the model for each computation. OpenRouter's listing makes the model available as a hosted option. The distinction between total and active parameters explains the model's name for size, since only the active portion does the work on each step.
- AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
- mixture-of-experts — A model built from many specialist sub-networks where only a few activate per token, giving big-model capability at small-model running cost.
- distillation — Training a small, cheap model to imitate a big one's outputs, keeping much of the capability at a fraction of the cost.
