MiniMax releases MiniMax-M3 in hardware-accelerated MXFP8 format, delivering lightning-fast inference for conversational agents and high-fidelity audio synthesis.

MiniMax has made a series of major releases on Hugging Face, including MiniMax-M3 (with native MXFP8 format) and MiniMax-Music3.

Microscaling FP8 Precision

By adopting the OCP Microscaling (MX) FP8 specification, MiniMax-M3 reduces memory bandwidth consumption by 50% compared to standard BF16, while preserving 99.8% of mathematical accuracy. This allows sub-50ms conversational latencies in real-time voice agents.
