MiniMax M3 428B-A23B — VRAM, speed & local setup
Written by Jakub Rusinowski · Last updated
MiniMax M3 — a natively multimodal MoE at roughly 428B total and 23B active, 1M-token context, minimax-community licence (June 2026). Previously listed as 230B-A10B; the id keeps its published URL. Datacentre-scale to self-host.
MiniMax M3 428B-A23B needs about 259 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.
VRAM and speed by quantization
Quoted against NVIDIA RTX 4090 (24 GB). Weights plus overhead only: this model's architecture is unpublished, so no KV cache is added.

Other MiniMax M3 sizes
MiniMax M3 428B-A23B — frequently asked questions
How much VRAM does MiniMax M3 428B-A23B need?
About 259 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does MiniMax M3 428B-A23B run on an RTX 4090 (24 GB)?
No. MiniMax M3 428B-A23B needs about 259 GB at Q4_K_M, more than a single RTX 4090's 24 GB. It needs a larger card, several GPUs, or Apple Silicon with enough unified memory — or it runs with part of the weights offloaded to system RAM, which is much slower.
How do I run MiniMax M3 428B-A23B locally?
No local Ollama tag. Ollama lists minimax-m3 only as a cloud-hosted ':cloud' tag, which runs on Ollama's servers, not your machine. Running the published tag would send your prompts to a hosted GPU rather than your own machine.
What other sizes does MiniMax M3 come in?
MiniMax M3 428B-A23B (259 GB), MiniMax M3-VL (140 GB), MiniMax M3.1 Flash 428B-A23B (259 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
