From the model card
MiniMax-M3 is a native multimodal model with 1M context. It has ~428B parameters and ~23B activated parameters.
Highlights:
MiniMax-M3-MXFP8 is the MXFP8 quantized variant of MiniMax-M3, a native multimodal model with 1M context. It has ~428B parameters and ~23B activated parameters.
M3 is powered by MiniMax Sparse Attention (MSA), a high-performance sparse attention operator designed for million-token contexts. Compared with GQA, MSA dramatically reduces the attention compute and memory footprint while preserving model quality.

M3 supports three reasoning modes through the thinking parameter:
enabled — Reasoning is always enabled.adaptive — M3 automatically determines when additional reasoning is beneficial.disabled — Reasoning is disabled to minimize latency and maximize throughput.Download the model:

We recommend the following inference frameworks to serve the model:
SGLang - see SGLang cookbook.
vLLM - see vLLM recipes.
Transformers - see Transformers docs.
We recommend the following parameters for best performance: temperature=1.0, top_p=0.95.
