Aug 11 (Reuters) - Nvidia is developing a new AI model family, Nemotron 4, with the goal of challenging top open-source models globally, The Information ‌reported on Tuesday, citing people who work on the project. A spate of recently disclosed hacks involving autonomous AI agents has added to the attention, especially because open models do not have ‌curbs on cybersecurity use. Nvidia pointed to previous remarks that ​it was working on Nemotron ‌4 but did not confirm the details in The Information's report. The chip giant formed ​a coalition last month with other companies to ​develop and share tools for AI ​safety and cybersecurity. It also released NeMo Switchyard, an open-source model-routing library designed ​to automatically direct AI tasks to the most suitable models.
