Llama Nemotron

NVIDIAOpen WeightsPending Human Review

Llama Nemotron is an NVIDIA language-model family. NVIDIA’s Llama-derived reasoning family post-trains and compresses Meta checkpoints for enterprise agents. Nano and Super were released in March; the 253B Ultra followed in April. Reasoning can be switched on for difficult tasks or off for concise responses. Super derives from Llama 3.3 70B; ancestry differs across tiers. Downloadable weights enable experiments and adaptation, subject to the checkpoint-specific license. Model-generated text and reasoning can be inaccurate, so capability claims should be checked in the intended application.
