It significantly improves on Llama 3.1 70B — notably +27pp MATH (77% vs 50%) — while maintaining the same 128K context window. ## At a Glance **Where Llama 3.3 70B leads** - 77.0% MATH — strong competition mathematics, +27pp vs Llama 3.1 70B - 88.4% HumanEval — excellent code completion - 68.9% MMLU-Pro — improved academic knowledge - 96.0% AI2 Reasoning Challenge - 128K context window - Open weights with strong ecosystem support **Where it lags** - Llama 3.3 License (not Apache 2.0) — commercial restrictions - Text-only: no vision capability - Superseded by Llama 4 Maverick for multimodal and 1M context needs - August 2024 knowledge cutoff **Best for:** Open-weight 70B deployments requiring strong math/coding; teams on Llama 3.1 70B seeking improvements without switching to Llama 4; complex STEM tasks. ## What Llama 3.3 70B Instruct Is Llama 3.3 70B Instruct (released December 6, 2024) is Meta's iterative improvement to the Llama 3.1 70B architecture, trained with enhanced data and improved instruction tuning. The most notable improvement is MATH: 77.0% vs approximately 50% for Llama 3.1 70B — a 27-percentage-point gain on competition mathematics. The model achieves 88.4% HumanEval (vs ~72% for 3.1 70B) and 68.9% MMLU-Pro, placing it solidly in the frontier open-weight tier at the 70B scale. It maintains the same 128K context window and architecture, making it a drop-in upgrade for most Llama 3.1 70B deployments. For teams choosing between Llama 3.1 70B and 3.3 70B, Llama 3.3 is the clear choice: substantially better math, coding, and knowledge with minimal migration overhead. ## Specifications | Field | Value | |---|---| | Organization | Meta | | Parameters | 70B (dense) | | Context window | 128,000 tokens | | License | Llama 3.3 License | | HuggingFace | [meta-llama/Llama-3.3-70B-Instruct](https://huggingface.co/meta-llama/Llama-3.3-70B-Instruct) | | Release date | December 6, 2024 | | Knowledge cutoff | August 2024 | | Modality | Text only | ## Pricing Open weights under Llama 3.3 License on Hugging Face.
