MiniMaxAI/MiniMax-M2.5
MiniMax M2.5 MoE language model (230B total / 10B active) for coding, agent toolchains, and long-context reasoning — native FP8 checkpoint
View on HuggingFaceGuide
Overview
MiniMax-M2.5 is part of the MiniMax M2 series of advanced MoE language models. It retains the M2 architecture (10B active, 230B total) and a 196K context per sequence.
Prerequisites
- OS: Linux
- Python: 3.10 - 3.13
- NVIDIA: compute capability >= 7.0; ~220 GB for weights + 240 GB per 1M context tokens
- AMD: MI300X / MI325X / MI350X / MI355X with ROCm 7.0+
