MiniMax released M3.1 Flash, a multimodal mixture-of-experts model with about 428 billion parameters, 23 billion active per token, and a context window of up to 1 million tokens, with weights on Hugging Face under the MiniMax community licence. The model card reports 73.7% on DeepSWE v1.1, 61.7 on OSWorld V2 and 82.2 on the CyberGym cybersecurity benchmark. MiniMax says inference is nearly three times faster than before and usage costs 70% less, and that an early version ran anonymously as Space Bunny and processed more than 200 trillion tokens.

Why it matters

A Chinese lab has put weights for a model it markets on cybersecurity performance in anyone’s hands, as US labs gate their most cyber-capable models.
