## Summary

Hugging Face says Mistral Large 4, nicknamed Le Chonk, is a multimodal Mixture-of-Experts model with about 1T total and 49B active parameters and a 1M-token context window. The model is released in FP8 and NVFP4 variants, with GGUF quants from Unsloth and the llama.cpp team, and day-0 support in transformers, vLLM, and llama.cpp. The post reports 82% on the Artificial Analysis Cyber Index and 61.7% on DeepSWE v1.1.

## Why it matters

The post gives the architecture, benchmark figures, and day-0 support paths for running the model locally or on endpoints, which makes it useful for teams weighing open-weight deployment.
