Built from Llama 3.3 70B via NVIDIA's distillation, it achieves higher MT-Bench than the 70B base model while using fewer parameters. ## At a Glance **Where Nemotron Super 49B leads** - 9.17 MT-Bench — highest open-weight MT-Bench score among Nemotron models - 88.3% Arena Hard — excellent instruction following - 73.7% BFCL v2 — strong tool use and function calling - 49B: smaller than 70B, more inference-efficient - NVIDIA's advanced alignment (RLHF + distillation) **Where it lags** - Llama 3.3 License — commercial restrictions apply - Text-only; no vision - Smaller than Nemotron Ultra 253B for maximum performance tasks - August 2024 knowledge cutoff **Best for:** High-quality instruction following and tool use at 49B scale; agentic pipelines requiring strong function calling; NVIDIA GPU deployments. ## What Llama 3.3 Nemotron Super 49B Is Llama 3.3 Nemotron Super 49B v1 (released April 14, 2025) is NVIDIA's "Super" tier in the Nemotron family — built on Llama 3.3 70B and reduced to 49B via knowledge distillation, then further aligned with NVIDIA's RLHF pipeline. The 9.17 MT-Bench score is exceptional: it exceeds the base Llama 3.3 70B while using fewer parameters, demonstrating that NVIDIA's alignment improvements can compensate for the parameter reduction. The 73.7% BFCL v2 score is also notable for agentic use cases. NVIDIA offers three Nemotron tiers: Nano (8B), Super (49B), and Ultra (253B). Super targets the sweet spot of high alignment quality with manageable inference cost. ## Specifications | Field | Value | |---|---| | Organization | NVIDIA | | Parameters | 49B (dense) | | Context window | 128,000 tokens | | License | Llama 3.3 License | | HuggingFace | [nvidia/Llama-3.3-Nemotron-Super-49B-v1](https://huggingface.co/nvidia/Llama-3.3-Nemotron-Super-49B-v1) | | Base model | Meta Llama 3.3 70B (distilled to 49B) | | Release date | April 14, 2025 | | Knowledge cutoff | August 2024 | | Modality | Text only | ## Pricing Open weights under Llama 3.3 License.
