NVIDIA releases NeMo Switchyard and Nemotron 3.5 Lightning to slash enterprise AI agent costs by 66%

Overview

On 11 August 2026, NVIDIA released NeMo Switchyard, an open-source dynamic routing framework, alongside Nemotron 3.5 Lightning, a 30-billion-parameter open mixture-of-experts model built specifically for high-volume, specialized agentic execution. The dual release directly addresses the primary financial and performance bottleneck facing enterprise deployment of autonomous AI agents: the exponential scaling of token costs and computational latency during multi-step execution. As technical organizations transition from passive conversational interfaces to persistent, long-running agentic workflows, execution pipelines frequently require dozens or hundreds of sequential API calls per task. Running every step through expensive top-tier frontier models quickly becomes commercially unviable.
