NOTICE

This is an experimental quantization of MiniMax M3 to NVFP4 for use on DGX Spark.

On top of that, REAP 50% to make it fix on 2x DGX Sparks instead of 4x.

NVFP4 uses w1/3 scales, so need either: https://github.com/scitrera/sglang/tree/nvfp4-w13-scale-normalization (or possibly sglang PR#27588) in place to properly use the calibration from this model.

The calibration is still a work in progress (hence "v0" model). Updates are planned to improve performance.

Re: REAP50, I've tested that it's coherent, but I haven't exhaustively tested the quality degradation associated with REAP50. YMMV.

Run with sparkrun; part of Spark Arena

https://sparkrun.dev https://spark-arena.com

To run with sparkrun on 2x DGX Spark Nodes:

sparkrun run @experimental/minimax-m3-v0-nvfp4-2x-reap50

MiniMax-M3 is a native multimodal model with 1M context. It has ~428B parameters and ~23B activated parameters.

Highlights:

Native Multimodality: M3 undergoes mixed-modality training from the very first step, enabling deeper semantic fusion across text, image, and video.
Context Scaling via Sparse Attention: M3 introduces MiniMax Sparse Attention (MSA) to improve long context efficiency. M3 delivers 9× prefill and 15× decode speedups compared to M2 at 1M context, reducing per-token compute to 1/20.
Coding & Cowork Capability: M3 achieves frontier-level performance across long-horizon agentic benchmarks, excelling in both coding and cowork.

MiniMax Sparse Attention (MSA)

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.

How to Use

M3 supports two reasoning modes:

thinking — for complex reasoning, agentic tasks, and long-horizon collaboration.
non-thinking — for latency-sensitive scenarios such as chat and code completion.

Local Deployment
