Mistral AI Releases Mistral Large 4 (Le Chonk): A 1.05T Parameter Multimodal MoE Model

Mistral AI has released Mistral Large 4, nicknamed 'Le Chonk,' a 1.05 trillion parameter open-weight multimodal Mixture-of-Experts model. This is one of the largest openly released models to date, combining text and multimodal understanding in a single MoE architecture. For developers, the open-weight release means the model can be self-hosted, fine-tuned, and integrated into proprietary pipelines without vendor lock-in. The MoE design means inference costs are lower than a dense model of equivalent parameter count, making deployment more feasible at scale. Benchmark firm evaluations are already circulating, giving developers early signal on where the model stands relative to peers.
