The model uses a mixture-of-experts architecture with 30 billion total parameters, while activating only 3 billion for each task, reducing the computing power needed to run it, Anadolu agency reported. The model is intended for tasks such as code review, tool use, security-alert monitoring and answering customer billing questions within larger AI-agent systems. Companies including cybersecurity firm CrowdStrike, legal AI provider Harvey and software-review platform CodeRabbit have tested and customized the model, said Nvidia. Alongside the model, Nvidia introduced NeMo Switchyard, an open-source routing library that automatically directs each AI task to the most capable and cost-efficient model available.
