- Nvidia released Nemotron 3.5 Lightning, an open 30B-parameter mixture-of-experts (MoE) model, described as highly customizable.
- Nvidia also released NeMo Switchyard, an open-source model routing library designed for AI agents.
Why it matters: By open-sourcing both a frontier-tier MoE model and an agent-routing library on the same day, Nvidia extends its reach beyond GPU sales into the developer-tooling layer of the agent stack — a category where it competes directly with framework providers.
