Amid heightened interest in Chinese open models, AI hardware vendor Nvidia introduced its latest open source model: Nemotron 3.5 Lightning.
Released on August 11, Nemotron 3.5 Lightning is a mixture-of-experts model that is designed for specialized tasks within larger multi-agent systems. Nemotron 3.5 Lightning can perform specific tasks such as code review, tool use, security alert monitoring and answering billing questions, Nvidia said. The vendor also released the model weights, code and recipes and training under the Linux Foundation’s OpenMDW 1.1 license, making it a truly open source model.
Nemotron 3.5 Lightning is part of Nvidia’s Nemotron 3 family of open models that was originally released last December.
