NVIDIA releases Nemotron 3 Ultra open agentic model via NIM and Hugging Face

NVIDIA released Nemotron 3 Ultra, positioned as a leading open agentic model, available via NVIDIA NIM microservices, multiple inference platforms, and downloadable weights on Hugging Face. The release reinforces NVIDIA's strategy of pairing its hardware dominance with a first-party open-model family, sitting atop an integrated stack of accelerated computing, NIM microservices, and NeMo customization tools — the goal being to make NVIDIA silicon the path of least resistance for building and serving agents.

The timing intersects with policy: the White House informed major AI labs that open-weight models — explicitly including Meta's Llama and NVIDIA's Nemotron — will be exempt from the government's new AI safety-testing framework, which stems from a June 2 executive order and subjects closed models from OpenAI, Anthropic, and Google to pre-release cybersecurity and hacking-capability review. The carve-out means freely downloadable, modifiable models won't face the same checks regardless of capability, a decision that will shape how labs weigh open versus closed release strategies.

That exemption is doubly notable this week given the AISI evals and OpenAI breach disclosure — critics like Ethan Mollick warned that 'the coming open-weights models will' reach the same dangerous cyber capabilities 'when they catch up,' making an open-weights safety exemption controversial. Nemotron 3 Ultra thus lands as both a capability release and a test case for the new regulatory posture.

NVIDIA also framed the release against a bullish market backdrop, citing a MarketsandMarkets projection that the generative-AI market reaches $1.66 trillion by 2033. The competitive question is whether Nemotron can win developer mindshare against Qwen, Llama/Muse Spark, and DeepSeek in the increasingly crowded open agentic-model field — NVIDIA's edge is less the model itself than the tightly integrated deployment stack around it.
