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

Ah, Nvidia. While the rest of the industry dithers over whether AI will save us or dissolve us, Nvidia is busy selling the tracks, the locomotives, and now the signal box. This week it announced Nemotron 3.5 Lightning and NeMo Switchyard, which sounds like either a railway junction or an especially frustrating level of a puzzle game. The pitch, delivered with the usual po-faced conviction, is that enterprises want "capability options" — because nothing says 'we have absolutely understood the problem' like a library that routes each prompt to the "most capable and efficient model available at each step of an agent workflow." The models are buses, your prompts are confused commuters, and Nvidia is the transport authority.

The efficiency bit is a masterpiece. You see, models aren't just better or worse; they are better or worse in direct proportion to how much compute you burn, and Switchyard exists to make sure you don't waste your expensive models on trivial questions. It's like hiring a QC barrister to open a jar of pickles because the trainee solicitor is otherwise engaged. And of course it's open-source, because nothing fills a CIO's heart with joy quite like maintaining a routing framework that is updated faster than the models it routes to. Nvidia is commoditising its own customers' dependence, one 'highly customizable' release at a time.

Still, one must salute the chutzpah. The same company that sells the GPUs, the CUDA, the networking, and the training platform now also tells you which model to use — and charges you for the switch. It's the technological equivalent of a casino owning the card-counter's strategy guide. There's a word for that level of vertical integration, and I believe it's pronounced 'margin'. So yes, enterprises, enjoy your capability options. Just remember that every option comes with a small handling fee, and the handling fee is Nvidia.
