Faster Models for Agentic Workloads
Nemotron 3.5 Lightning is built for speed. The models are designed to be faster than previous versions while remaining customizable, letting developers tune them for specific use cases. For agentic workflows, where an AI system might need to make multiple calls in sequence, that speed matters. A slower model can stall an entire pipeline. Customization is the other half of the pitch. Developers aren't stuck with a one-size-fits-all model. They can adjust the model to fit their particular domain, their data, or their performance requirements. That combination of speed and flexibility is what NVIDIA is betting on. The idea is that a developer building a customer service agent doesn't need the same model as someone building a code assistant. Lightning gives them a base to start from.
A Router That Balances Cost, Latency, and Accuracy
The second launch, NeMo Switchyard, tackles a different problem. When you have multiple models available, you have to decide which one to use for each request. Switchyard handles that routing automatically. It weighs cost, latency, and accuracy to pick the right model for the job. A simple query might go to a cheap, fast model. A complex reasoning task might get routed to a more powerful one. That balancing act is central to keeping agentic systems practical. Without a router, developers either overpay by using the biggest model for everything, or they risk accuracy by using a small one for hard problems. Switchyard is meant to sit in the middle and make that call on the fly. It's a layer of intelligence that sits above the models themselves, deciding which one gets the work.
The Agentic AI Push
These launches are part of NVIDIA's broader effort to support agentic AI. Agentic AI refers to systems that don't just answer questions but take actions—calling tools, making decisions, and completing multi-step tasks. Those systems are more demanding than a simple chatbot. They need models that respond quickly and a way to manage the mix of models in play. NVIDIA is positioning both products as answers to those demands. The Lightning models give agents the speed they need to operate in real time. Switchyard gives
