Model Details
Llama 3.3 Nemotron Super 49B v1
Quick answer: Llama 3.3 Nemotron Super 49B v1 is NVIDIA's April 2025 distilled and aligned 49B model, scoring 88.3% Arena Hard, 73.7% BFCL v2, and 9.17/10 MT-Bench. 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.
