Introducing NVIDIA Nemotron 3.5 Lightning⚡

An open 30B MoE model with 3B active parameters, built for always-on agents to complete high-volume, specialized tasks faster.

It delivers up to 4x the output speed of similar-sized models.

Lightning pairs strong accuracy with speed.

On PinchBench, it reaches 86% accuracy while completing 10,000 tasks 35% faster than Qwen3.6 35B at similar accuracy.

Lightning is built to specialize.

Post-train Nemotron 3.5 Lightning with NVIDIA NeMo for your domain data, tools, workflows and policies.

Across cybersecurity, coding, legal and energy tasks, post-training improves accuracy for specialized work.

Long-running agents spend most of their time executing: calling tools, validating results and delegating work.

Nemotron 3.5 Lightning is built for this high-volume execution, at a size that can run anywhere from an NVIDIA DGX Spark to the data center.

Not every step in an agent workflow needs the same model.

That’s why we’re also releasing NVIDIA NeMo Switchyard, a new open source library for model routing.

Use frontier models for complex reasoning and planning, and Lightning for high-volume, specialized execution.
