Mistral releases open weights for Mistral Large 4, a 1-trillion-parameter model

Mistral published the weights of Mistral Large 4 ("Le Chonk"), a natively multimodal mixture-of-experts model with about 1 trillion parameters (52 billion active) and a 1M-token context, under a modified MIT licence. Mistral calls it the best open-weight model for coding; it is also offered on its API at $0.70 per million input tokens and $2.10 per million output tokens.
