O MiniMax

Osnovano 2021 · Shanghai, China

MiniMax (上海稀宇科技, Shanghai Xiyu Technology) is a Shanghai-based AI startup founded in late 2021 by Yan Junjie (former vice president of SenseTime). The company has built a portfolio of consumer AI products including the Talkie and Hailuo AI chatbots, abab text models, and the Hailuo Video generative video line. MiniMax has raised over $850M from investors including Alibaba, Tencent, Hillhouse Capital and IDG Capital, with a 2024 valuation above $2.5B. MiniMax-01, released January 2025, was the company's first open-weight frontier release and introduced lightning attention at scale — a linear-attention variant — with a 4M token training context and 1M context inference window.

Arhitektura

Hybrid Lightning-Attention + Softmax-Attention Mixture-of-Experts

MiniMax-01 (MiniMax-Text-01 base plus MiniMax-VL-01 vision variant) combines lightning attention — MiniMax's linear-attention design — with periodic softmax attention layers (every 8th layer is full softmax). The architecture has 80 layers with 6,144 hidden size, and MoE feed-forwards with 32 experts and top-2 routing yielding 45.9B active out of 456B total. The hybrid design enables 4M-token effective training context and 1M-token inference context, with near-linear compute per token in the lightning-attention layers. MiniMax describes MiniMax-01 in its technical paper as the first production-scale linear-attention LLM. The VL variant adds 336x336 image patch encoding for vision input. Released January 2025 under the MiniMax Model License with open weights on Hugging Face alongside hosted API access via the MiniMax Open Platform.
