NVIDIA Releases Open Model Nemotron 3.5 Lightning for AI Agents
NVIDIA has introduced a new open model, Nemotron 3.5 Lightning, which offers high generation speed and accuracy for AI agents.
NVIDIA has released the open model Nemotron 3.5 Lightning for continuously operating AI agents.
This model features 30 billion parameters, of which only 3 billion are activated. As a result, the generation speed is up to four times higher than that of comparable-sized models.
In PinchBench, it demonstrated an accuracy of 86% and completed 10,000 tasks 35% faster than Qwen3.6 35B at comparable accuracy.
The model can be fine-tuned on custom data, tools, and workflows. It is compact enough to run on DGX Spark.
Along with it, NVIDIA opened NeMo Switchyard - a library that distributes different stages of agent work among models. Complex reasoning and planning can be assigned to advanced models, while mass task execution can be handled by the fast Lightning.
NVIDIA also published weights, data, and training recipes.
It is available for free through OpenRouter.
Why it matters
AnalysisThis model opens new opportunities for AI agent developers, allowing them to fine-tune the model to their needs. Its high generation speed and accuracy make it attractive for a wide range of applications.
