Meta's Llama 3.3: Open-Source AI Gets Smarter, Free to Use

The Release

Meta released Llama 3.3 70B on December 6, 2024, with integration and adoption accelerating through February 2025. Available for download on Hugging Face under Meta's Community Licence, it allows commercial use for most applications. On MMLU, it scores 86.0% vs 82.0% for Llama 3.1 70B. On HumanEval coding, it scores 88.4%, surpassing GPT-4 Turbo's 87.1%. On MATH, it achieves 77.0% — firmly frontier-class for this model size.

What Changed from 3.1 to 3.3

Architectural changes are modest — improvements come from expanded and cleaned training data, improved instruction fine-tuning data, and a revised RLHF pipeline. Meta's researchers found data quality improvements yielded larger benchmark gains than architectural changes. The model uses grouped query attention for efficient inference, supports 128K token context, and handles tool use natively for direct use in agent pipelines.

Hardware Requirements

Running Llama 3.3 70B in BF16 precision requires approximately 140GB VRAM — two A100 80GB GPUs. Quantised GGUF Q4 versions reduce this to around 40GB for single-GPU deployment. The llama.cpp project supports CPU-only inference at 3-5 tokens/second on a modern 32-core server CPU, suitable for non-latency-sensitive batch processing.

Ecosystem Adoption

Within two weeks, Llama 3.3 70B was integrated into Ollama, LM Studio, Perplexity, and Groq's inference API (achieving 750+ tokens/second on their LPU hardware). This ecosystem integration velocity is unique to Meta's models — no other lab produces open-weight models achieving this level of third-party adoption speed.
