  "account": "Mistral has unveiled Mistral Large 4, or le Chonk, a 1-trillion-parameter model that it claims is the most powerful open-weight AI model developed outside of China. The model is currently in preview for developers, cybersecurity professionals, and government entities, with a wider release set for later this month. According to CNBC, ML4 was trained on 4,000 Nvidia Grace Blackwell GPUs over a two-month period in Mistral's European data centers. When its core parameters are released, ML4 is expected to rank among the top open-weight models globally on benchmark performance, according to Mistral. The company emphasized that ML4 is the strongest open-weight model developed outside China by a substantial margin. However, ML4 still falls short in areas such as coding. Mistral CEO Guillaume Lample, co-founder and chief scientist of the company, stated that the model's capabilities will improve as training capacity increases, following their Series D fundraising. Lample also mentioned that the cyber defense capabilities of ML4 will enable enterprises and governments to protect themselves against threat actors who jailbreak closed models to carry out cyber attacks.",
