Llama 3.3 70B Instruct — MXFP4 GGUF

MXFP4 quantization of meta-llama/Llama-3.3-70B-Instruct, a 70B parameter multilingual instruction-tuned language model from Meta.

About the Model

Llama 3.3 70B Instruct is an auto-regressive transformer optimized for multilingual dialogue use cases. It outperforms many open-source and closed chat models on common industry benchmarks.

• 70B parameters — dense transformer architecture
• 128K context window with Grouped-Query Attention (GQA)
• 15T+ tokens pretrained on publicly available data
• Multilingual — English, German, French, Italian, Portuguese, Hindi, Spanish, Thai
• Tool calling support with native function calling
• Text-only — no vision/multimodal capabilities

Quantization

This GGUF was quantized from Unsloth's official F16 GGUF using llama.cpp (build 537). The F16 weights were dequantized to F32 during quantization, then quantized to MXFP4 format.

MXFP4 (Microscaling FP4) uses block-wise quantization with shared exponents per block.

Note: This is a text-only model. No mmproj/vision files needed.
