Llama 3.3 70B

70B parameter open-weight model. December 2024 Llama release with improved instruction following over 3.1 70B at the same 70B parameter count and 128K context. Q4 requires ~41 GB VRAM — suited for RTX 6000 Ada (48 GB), multi-GPU setups, or Mac with 64 GB+ unified memory.

Model overview

Llama 3.3 70B is Meta's refreshed 70B release, improving instruction-following over the earlier Llama 3.1 70B checkpoint while keeping the same parameter count and 128K context window. It covers a broad set of workflows well — chat, coding, RAG, agentic tool-use, and summarization all appear as tagged strengths — making it a versatile pick if you have the hardware to run a 70B-class model. Q4 quantization needs roughly 41 GB of VRAM, which fits a single 48 GB workstation card like the RTX 6000 Ada, a multi-GPU rig, or a Mac with 64 GB or more of unified memory. For most single consumer-GPU setups, a smaller Llama or Qwen checkpoint will be more practical.

Will Llama 3.3 70B run on your machine?

Llama 3.3 70B is 70B parameters and needs 42.5 GB of VRAM at Q4_K_M41 GB of weights plus 1.5 GB of runtime overhead for the inference server itself.

Comfortable means VRAM clears the requirement by 2 GB or more. Tight means it covers the requirement with no margin. CPU offload means the model does not fit in VRAM but system RAM is at least 1.6× the weights, so it will run at reduced speed — expect roughly 1–5 tokens per second. Figures are weights plus a fixed runtime overhead and exclude KV-cache growth, which scales with context length.

Apple Silicon shares one pool of memory between the system and the GPU, so a model cannot use all of it. These rows apply the same 75% usable fraction the Compatibility Checker uses, which is why a 36 GB Mac is graded on less than 36 GB.
