MiniMax-M3: hardware requirements
MiniMax-M3 needs about 265 GB of memory at Q4 quantization — a 261 GB download plus room for context and overhead. That is beyond consumer hardware; use it through an API instead.
This is a mixture-of-experts model. Only a fraction of its 427B parameters are used for each token, so it runs faster than its size suggests — but all of it still has to fit in memory. The speed is that of a small model; the memory requirement is that of a large one. More on this →

Download sizes by quantization
Lower quantization means a smaller file and less memory, at some cost to quality. Q4_K_M is the usual starting point. What is this?
| Quant | Download | RAM @ 4K | RAM @ 32K | Source |
|---|---|---|---|---|
| Q4_K_Mrecommended | 261 GB | 265 GB | 269 GB | measured |
| Q5_K_M | 305 GB | 309 GB | 313 GB | measured |
| Q6_K | 369 GB | 373 GB | 377 GB | measured |
| Q8_0 | 454 GB | 457 GB | 461 GB | measured |
| BF16 | 854 GB | 858 GB | 861 GB | estimated |
“Measured” sizes are read from published GGUF files (bartowski/MiniMax-M3-GGUF). “Estimated” sizes are derived from the parameter count and are typically within a few percent. The RAM columns add the context cache and runtime overhead to the download size.
