Nvidia releases Nemotron 3.5 Lightning and NeMo Switchyard to give enterprise AI capability options

Nvidia announced Nemotron 3.5 Lightning, a highly customizable large‑language‑model framework, alongside NeMo Switchyard, an agentic AI router that lets enterprises dynamically direct inference traffic across multiple models. The duo is positioned to give organizations granular control over model selection while maintaining a unified deployment surface, though the added routing layer can introduce latency and operational overhead.

⚡ Key Takeaways

• Nemotron 3.5 Lightning offers a customizable LLM architecture that can be fine‑tuned for specific enterprise workloads.
• NeMo Switchyard acts as an agentic router, enabling dynamic model selection and load‑balancing across heterogeneous inference backends.
• The routing layer trades off raw inference speed for flexibility, potentially adding a few milliseconds of latency per request.
• Integration involves configuring routing rules in the NeMo Switchyard API and connecting Nemotron endpoints via the NeMo SDK.
• The solution presumes an Nvidia‑based inference stack; it may not interoperate seamlessly with non
