CoreWeave has introduced RL Rollouts, an infrastructure feature that loads new model weights directly into live inference deployments during reinforcement learning without disrupting active requests. NVIDIA and You.com used the feature to post-train Nemotron 3.5 Lightning for web search.
NVIDIA AI has released Nemotron-Labs-3-Competitive-Coding on Hugging Face. The competitive-programming specialist model is based on Nemotron-3-Ultra and powers the team's performance on the IOI 2026 problem set.
elvis says the new Nebius AI Builder Program includes more than $400 in credits and discounts on day one for Nebius Token Factory, Tavily, and launch partners, plus runnable blueprints and free courses built with NVIDIA. Joining is free.
The 100-million-parameter model tracks who spoke when, including when voices overlap, and supports up to eight speakers. It is available on huggingface.
NVIDIA AI reports a 14.72% error rate for Nemotron 3 Diarization on voicearena_ai’s initial Diarization-Bench, about 24% lower than the runner-up.
Nemotron 3 Diarization can be tried in a Hugging Face Space. A Hugging Face blog covers how the model works and how to get started.
Sluicebox’s AI supplier agent Lucy uses NVIDIA Nemotron 3 Ultra to collect and check supplier data while engineers design a data center’s carbon footprint. In Sluicebox’s tests, Nemotron improved accuracy, cut costs by 51–80%, and returned responses up to 2x faster.
