Notes

  • Mistral Large 4 is a 1T-parameter mixture-of-experts model (128 routed experts, 4 active per token, plus 1 shared expert; ~52B active parameters) with image input and a 1M-token context window.
  • The source checkpoint is block-scaled FP8. All GGUFs here are quantized from it; for a version that keeps the original NVFP4 experts, see ggml-org/Mistral-Large-4-1T-A52B-NVFP4-GGUF.
  • The IQ2_XXS output quantizes the routed expert gate/up projections to IQ2_XXS and the expert down projections to IQ2_XS. Attention, the sparse-attention indexer, the shared experts, the dense first layer, the embeddings and the output head are kept at Q8_0.
  • The IQ2_XXS is calibrated with an imatrix computed on 36 chunks of 8,192 tokens.
  • Reasoning depth is set with reasoning_effort: low, medium or high (the default). Reasoning cannot be turned off.
  • Recommended sampling (stored in the GGUF metadata): temperature 1.0, top_p 0.95.
