CE QUE C'EST

MiniMax-M1 is an open-weight reasoning model MiniMax released in June 2025. MiniMax was founded in Shanghai in 2021 by Yan Junjie and others. M1 uses a hybrid attention design that combines standard full-attention layers with linear-attention layers to cut the compute cost of long-sequence reasoning, and its stated context window reaches the million-token range. With 456B total parameters activating about 46B per token, it is a large-scale MoE reasoning model whose weights are released under an open licence. The company also runs generation product lines such as Hailuo.

Pourquoi il compte

It mixes linear and full attention and pushes context to a million tokens to cut the cost of long-sequence reasoning; among the larger open-weight reasoning models, it is a concrete landing of the open-weight camp on the reasoning track.
