☕ Ko-fi One-time tip My eternal gratitude

Your help will motivate me and would go into further improving my workflow and coverings fees for storage, compute and may even help uncensoring bigger model with rental Cloud GPUs.


Read before purchase/download:

These GGUF files require a runtime/backend with MiniMax-M3 GGUF architecture support to use, such as the latest version of llama.cpp and the latest version of LM Studio. They are not guaranteed to work in Ollama, KoboldCpp, Jan, or older llama.cpp builds unless those runtimes support the minimax_m3_vl architecture in GGUF format.

Important GGUF compatibility notice

These GGUF files are provided as the best currently available conversion based on the present upstream llama.cpp MiniMax-M3 GGUF work.

Please purchase only if you understand that not every frontends and/or backends support the minimax_m3_vl architecture.

Performance

Metric This model Original model (MiniMaxAI/MiniMax-M3)
KL divergence 0.0258 0 (by definition)
Refusals 8/100 98/100

Lower refusals indicate fewer content restrictions, while lower KL divergence indicates more closeness to the original model's baseline. Higher refusals cause more rejections, objections, pushbacks, lecturing, censorship, softening and deflections.

Usage

Right now works with the latest version of llama.cpp and the latest version of LM Studio.

Compatibility notice

These GGUF files require a runtime/backend with MiniMax-M3 GGUF architecture support.

Tested working on my setup:

  • MiniMax-M3-compatible llama.cpp build`
  • llama-server
  • llama-ui
  • Tool calling with SearXNG/web search
  • Latest version of LM Studio

Expected / likely compatible:

  • Unsloth Studio, if using a current version with MiniMax-M3 support

Not currently supported / not guaranteed:

  • Older versions of LM Studio
  • Older or mainline llama.cpp builds without MiniMax-M3 support
  • Ollama, KoboldCpp, Jan, or other third-party frontends unless their bundled backend supports the minimax-m3 GGUF architecture

If you see an error such as:

unknown model architecture: 'minimax-m3'

or

failed to load model

This does not mean the GGUF file is broken, it just means that your runtime/backend does not support MiniMax-M3 GGUF yet.

Right now MiniMax-M3 GGUFs should be compatible with the latest version of: llama.cpp as well as the latest version of LM Studio.

And with: Unsloth Studio

To decrease the probability of unforseen issues due to outdated versions, be sure to use that latest transformers version (very important, won't work unless you either use 5.12.0 or 5.12.1), the latest CUDA versions (very important, do not use anything lower to avoid unforseen issues: 13.0 or 13.1 or 13.2 or 13.3), the latest PyTorch version (very important, use the latest versions of torch either 2.12.0+cu132 or 2.12.1+cu132 and torchvision either 0.27.0+cu132 or 0.27.1+cu132) and the latest Triton versions (3.6.0 or 3.7.0).

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 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.
