# Nvidia releases Nemotron 3.5 Lightning open source model

> Nvidia has released Nemotron 3.5 Lightning, a 30 billion parameter model that is free to download, use, and modify, available on Hugging Face and Nvidia's own site. The pitch is efficiency: it runs on a single GPU inside a PC or laptop, claims roughly 4x faster output than comparable models, and completes agent tasks about 30 percent quicker. The target is autonomous agent workloads, the multi-step, tool-using jobs where latency and cost pile up fast. By open-sourcing a model that fits on one GPU, Nvidia is nudging developers toward running capable agents locally rather than paying per token to a hosted API, which conveniently also sells more of Nvidia's hardware. Nvidia is better known as the company selling shovels in the AI gold rush, so shipping its own open model is a notable move up the stack. It also flagged Nemotron 4, a 1 trillion-plus parameter successor due in late fall. For technologists, the appeal here is practical: a genuinely usable open model small enough to tinker with on your own machine.
