Llama Nemotron – A series of reasoning models launched by NVIDIA
What is Llama Nemotron?
Llama Nemotron is a series of inference models launched by NVIDIA, focusing on reasoning and various agentic AI tasks. The models are based on the open-source Llama model and enhanced with reasoning capabilities through NVIDIA’s post-training, excelling in areas such as scientific reasoning, advanced mathematics, programming, instruction following, and tool invocation. The Llama Nemotron model family includes three types: Nano, Super, and Ultra, catering to a wide range of enterprise-level AI agent needs, from lightweight inference to complex decision-making.
Nano (llama-3.1-nemotron-nano-8b-v1) is fine-tuned from Llama 3.1 8B and designed specifically for PCs and edge devices.
Super (llama-3.3-nemotron-super-49b-v1) is distilled from Llama 3.3 70B and optimized for data center GPUs, achieving the best accuracy under the highest throughput.
Ultra (Llama-3.1-Nemotron-Ultra-253B-v1) is distilled from Llama 3.1 405B and is designed as the most powerful intelligent agent tailored for multi-GPU data centers. In a series of benchmark tests, Llama-3.1-Nemotron-Ultra-253B-v1 performs on par with DeepSeek R1 and outperforms Meta’s newly released Llama 4 Behemoth and Llama 4 Maverick.
