Nvidia has launched Nemotron 3.5 Lightning, a 30-billion-parameter AI model optimized for specialized agent tasks, paired with NeMo Switchyard, an open-source routing library that dynamically assigns each step of an AI workflow to the most cost-effective and suitable model, cutting task costs to roughly a third of running large frontier models alone.
This Wire brief sits within Fusion42's coverage of AI & ML, and 11 sources have reported it between 11 Aug 2026 and 18 Aug 2026.
◆ ◆ The Wire takeaway
You can cut AI agent task costs sharply by integrating Nvidia's open-source Switchyard routing with their Lightning model, gaining control over workflow efficiency without rebuilding infrastructure. This opens a new path to compete on AI services by trimming compute spend while maintaining frontier-level accuracy.
