MiniMax-M3.1-Flash

by MiniMax MiniMaxAI/MiniMax-M3.1-Flash

MiniMax-M3.1-Flash is an open-weight model for image and text to text from MiniMax, released under other. It has 220.5B parameters and a 1,048,576-token context. At 16-bit it needs about 529.2 GB of GPU memory, which fits on 2x MI355X from $5.18 an hour; at 4-bit, 132.3 GB on 1x MI300X from $1.85, at the lowest prices in the SAVRN Index. It draws 357 downloads a month.

MiniMax-M3.1-Flash is a native multimodal mixture-of-experts model for coding, agentic workflows, computer use, and cybersecurity. It supports text, image, and video inputs with a context window of up to 1M tokens.

Model Card

MiniMax-M3.1-Flash is a native multimodal mixture-of-experts model for coding, agentic workflows, computer use, and cybersecurity. It supports text, image, and video inputs with a context window of up to 1M tokens. Building on MiniMax-M3, M3.1-Flash improves task performance and inference efficiency with sparse attention throughout the model, quantization-aware training, and DSpark speculative decoding. - Agents’ Last Exam: Official Overall setting; full-set results from the official ALE leaderboard only. Blank = no official result (CLI-only excluded), not zero. Results are for the official weights; third-party quantizations may differ. M3.1-Flash retains M3’s core mixture-of-experts…

Questions About MiniMax-M3.1-Flash

How much GPU memory does MiniMax-M3.1-Flash need?

About 529.2 GB at 16-bit and 132.3 GB at 4-bit: the weights (220.5B parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run MiniMax-M3.1-Flash on?

At 16-bit, 2x MI355X from $5.18 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

What license is MiniMax-M3.1-Flash released under?

other, as its publisher declares it. Read the license text before commercial use.

What is MiniMax-M3.1-Flash's context length?

1,048,576 tokens, from the maximum position embeddings in its published configuration.

Qwen

As the frontier of foundation models pushes toward ever-larger parameter counts and ever-longer context windows, the question is no longer just how much we can scale, but how efficiently we can do so. Sustainable progress toward artificial general intelligence (AGI) that benefits everyone demands architectural innovation. Today, we are sharing a concrete step in that direction: Qwen3.8-Flash-Next. This experimental preview of the architecture that will underpin Qwen4 is built around a fundamental rethinking of how the core components of modern large language models (LLMs) interact at scale.

This model has had its safety alignment substantially removed via abliteration (orthogonalizing the refusal direction out of the residual stream). It will comply with harmful, unethical, or illegal requests the original Qwen3.8-Flash-Next would refuse.

You assume full responsibility for how you use it and everything it generates; add your own safety and moderation layers before any deployment.

Qwen3.8-Flash-Next-MLX-oQ3-MTP

Robot Haus

A sensitivity-guided, mixed-precision MLX conversion of Qwen/Qwen3.8-Flash-Next, rebuilt directly from the official BF16 checkpoint with the model's matching native MTP block preserved. oQ3 uses a 3-bit affine base and spends additional precision on sensitive modules. Layer sensitivity was measured with a validated quantized calibration proxy, while every released weight was quantized from the official BF16 checkpoint. The result is a compact model with 746 higher-precision module overrides rather than a uniform 3-bit layout. The upstream tokenizer, current chat template, vision processor, generation configuration, licence, and native MTP configuration are retained. In a compatible oMLX…
