Engineering specifications, VRAM sizing, commercial licensing terms, token economics, and empirical benchmark evaluations.
Llama 3.3 70B Instruct is Meta's high-efficiency open foundation model. Through upgraded post-training distillation, iterative DPO (Direct Preference Optimization), and supervised alignment on Llama 3.1 405B synthetic data, Llama 3.3 70B delivers capabilities matching the earlier 405B flagship model at a fraction of the hardware compute cost.
In FP16 unquantized precision, Llama 3.3 70B requires ~145 GB VRAM (2x A100 80GB). With 8-bit quantization (FP8/INT8), it fits on 80 GB VRAM (1x A100/H100). With 4-bit quantization (AWQ/GGUF Q4_K_M), it requires only 42-48 GB VRAM, running smoothly across two consumer Nvidia RTX 4090 GPUs (24GB each) or on an Apple Mac Studio (M2/M3/M4 with 64GB+ unified memory).
