Dataset updated 2026-10-24MiniMax M3.1 Flash
MiniMax M3.1 Flash publishes its weights, but at 428B parameters (23B active per token) no consumer machine holds the checkpoint. This page covers the access paths that work and the open models that actually run locally.

Why you can't run MiniMax M3.1 Flash locally
At 428B parameters (23B active per token), a Q4-class build of MiniMax M3.1 Flash would need roughly 257 GB, only a maxed-out 512GB Mac Studio could even hold the weights, with no real headroom. That figure is arithmetic, not opinion: 0.6 GB per billion parameters is the standard Q4 rule we apply across the whole catalog. The weights themselves are public (official source linked below); capacity, not licensing, is the wall.
What works instead: the hosted API. For most workloads, the open models below deliver the same job on hardware that fits under a desk.
MiniMax's next Flash model (Oct 2026): a native multimodal MoE (text, image and video input) with about 428B total and 23B active parameters per token and a context window of up to 1M tokens, built for coding, agents, computer use and cybersecurity. Per MiniMax's model card: DeepSWE v1.1 73.7% and OSWorld V2 61.7. Weights on Hugging Face under the MiniMax community license; ollama run minimax-m3.1-flash:cloud streams it from Ollama Cloud.

Frequently asked questions
Can I run MiniMax M3.1 Flash locally?
Not on hardware you can buy. The weights are public, but MiniMax M3.1 Flash is a 428B-parameter model (23B active), and a Q4-class build would need roughly 257 GB, only a maxed-out 512GB Mac Studio could even hold the weights, with no real headroom. Until the ecosystem ships a smaller official build, the API or a smaller open model is the practical path.
How do I access MiniMax M3.1 Flash?
Through the vendor's hosted API. The official source is linked on this page.
What is the best local alternative to MiniMax M3.1 Flash?
Qwen3 235B A22B is the strongest local model we track (235B, from 192 GB machines), with Qwen3.5 122B-A10B Instruct close behind. Both run on a single high-memory Mac or GPU, see their pages for exact hardware.
