What is Llama Nemotron
Llama Nemotron is a series of reasoning models launched by NVIDIA, focusing on reasoning and various agentic AI tasks. The models are based on the open-source Llama models and are post-trained by NVIDIA to add reasoning capabilities, excelling in scientific reasoning, advanced mathematics, programming, instruction following, and tool calling. The Llama Nemotron model family includes three types: Nano, Super, and Ultra, respectively suited for a variety of enterprise-level AI agent needs ranging from lightweight reasoning to complex decision-making.
Nano (llama-3.1-nemotron-nano-8b-v1) is fine-tuned from Llama 3.1 8B and is designed specifically for PCs and edge devices.
Super (llama-3.3-nemotron-super-49b-v1) is distilled from Llama 3.3 70B and is optimized for data center GPUs, achieving the best accuracy at the highest throughput.
Ultra (Llama-3.1-Nemotron-Ultra-253B-v1) is distilled from Llama 3.1 405B and is designed to build the strongest agent for multi-GPU data centers. In a series of benchmark tests, Llama-3.1-Nemotron-Ultra-253B-v1 is comparable toDeepSeek R1and outperforms Meta's newly released Llama 4 Behemoth and Llama 4 Maverick.
