At SIGGRAPH 2026, Nvidia unveiled Nemotron 3.5 Lightning, a new family of AI models designed for efficient inference, along with Switchyard, a testing framework for AI models. The announcement was made on August 13, 2026, according to Nvidia's official blog.
Nemotron 3.5 Lightning includes models optimized for various tasks, with sizes ranging from 8B to 450B parameters. These models are designed to deliver high performance with reduced latency, targeting enterprise applications that require real-time AI responses.
Switchyard is a new tool that allows developers to test and evaluate AI models in a simulated environment before deployment. It aims to reduce the risk of model failures in production by providing a sandbox for stress-testing under realistic conditions.
Nvidia also announced that Nemotron 3.5 Lightning models will be available on the NVIDIA NIM platform, part of the AI Enterprise suite. The company emphasized the importance of open-source models and collaboration with the community to advance AI innovation.
