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
Q8_0	18 GB	24 GB	52 GB	measured
BF16	21 GB	27 GB	55 GB	measured

“Measured” sizes are read from published GGUF files (llmfan46/gemma-4-31B-it-uncensored-heretic-NVFP4-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.
