Nemotron 3.5 Lightning
READER SUMMARYAn open 30-billion-parameter mixture-of-experts model with 3 billion active parameters and up to one million tokens of context, built for tool use and high-volume execution inside long-running agents. NVIDIA released commercial-use weights, training data and recipes with local, data-center and hosted deployment paths.
Why this model scores 75.4
Capability 67 reflects solid reasoning and coding results below frontier systems. Autonomy 72 reflects tool use and long-running agent execution rather than frontier planning. Deployment 98 reflects global open weights, commercial use, local hardware and broad hosted distribution. Misuse 68 reflects accessible coding and tool-use capacity. Control difficulty 82 reflects customizable local operation and removable guardrails, partly offset by published data, recipes and safety guidance.
News tied to Nemotron 3.5 Lightning
The model score of 75.4 rates this model's risk profile. The overall Doom Index of 62.1 measures the recalibrated complete evidence corpus. These values answer different questions.
Each article's leave-one-out Doom Index contribution is divided equally among the exact models named on that article. This prevents multi-model evidence from being claimed in full on several model pages. Model risk scores are recalculated from their technical profile and related news, but never feed back into the overall index.
NVIDIA releases open Nemotron 3.5 Lightning for always-on agents
NVIDIA released Nemotron 3.5 Lightning, a 30-billion-parameter mixture-of-experts model with 3 billion active parameters, open weights, training data and recipes. The commercially usable model targets high-volume execution in long-running agents, runs on local hardware or data centers, and is distributed through open repositories, hosted APIs and cloud partners.
