How much RAM does MiniMax-H3 need?

MiniMax-H3 needs about 64 GB of memory at Q4_K_M quantization with 4K context. The download itself is 54 GB; the extra covers the context cache and runtime overhead.

Can I run MiniMax-H3 on a laptop?

Yes — it runs comfortably on a machine with 128GB RAM, for example Mac Studio M3 Ultra.

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	54 GB	64 GB	64 GB	measured
Q5_K_M	48 GB	57 GB	57 GB	measured
Q6_K	27 GB	33 GB	33 GB	estimated
Q8_0	35 GB	43 GB	43 GB	estimated

“Measured” sizes are read from published GGUF files (Abiray/MiniMax-H3-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.
