Mistral Large 4 open weights released; self-hosting requires substantial hardware

By PulseAugur Editorial · [5 sources] ·

Mistral AI has released the open weights for its Mistral Large 4 model, a 1.05 trillion parameter mixture-of-experts architecture. This model, nicknamed "Le Chonk," features a 1 million token context window and supports multimodal inputs. While the active parameter count per token is around 52 billion, making inference costs comparable to smaller models, the total parameter count necessitates significant hardware for self-hosting, with weights ranging from hundreds of gigabytes to over a terabyte. The model's license, a modified MIT license, includes stipulations for commercial use as a service. AI

IMPACT Accelerates research and development by enabling broader access to a powerful, large-scale open-weight model, though self-hosting requirements present a significant barrier.
