Usage

If you are unsure how to use GGUF files, refer to one of TheBloke's READMEs for more details, including on how to concatenate multi-part files.

Provided Quants

(sorted by size, not necessarily quality. IQ-quants are often preferable over similar sized non-IQ quants)

Link	Type	Size/GB	Notes
GGUF	imatrix	0.1	imatrix file (for creating your own quants)
GGUF	i1-IQ1_S	2.2	for the desperate
GGUF	i1-IQ1_M	2.4	mostly desperate
GGUF	i1-IQ2_XXS	2.6
GGUF	i1-IQ2_XS	2.9
GGUF	i1-IQ2_S	3.0
GGUF	i1-IQ2_M	3.3
GGUF	i1-Q2_K_S	3.3	very low quality
GGUF	i1-Q2_K	3.5	IQ3_XXS probably better
GGUF	i1-IQ3_XXS	3.6	lower quality
GGUF	i1-IQ3_XS	3.9
GGUF	i1-Q3_K_S	4.0	IQ3_XS probably better
GGUF	i1-IQ3_S	4.1	beats Q3_K*
GGUF	i1-IQ3_M	4.2
GGUF	i1-Q3_K_M	4.4	IQ3_S probably better
GGUF	i1-Q3_K_L	4.8	IQ3_M probably better
GGUF	i1-IQ4_XS	4.9
GGUF	i1-Q4_0	5.2	fast, low quality
GGUF	i1-IQ4_NL	5.2	prefer IQ4_XS
GGUF	i1-Q4_K_S	5.2	optimal size/speed/quality
GGUF	i1-Q4_K_M	5.4	fast, recommended
GGUF	i1-Q4_1	5.7
GGUF	i1-Q5_K_S	6.2
GGUF	i1-Q5_K_M	6.4
GGUF	i1-Q6_K	7.3	practically like static Q6_K
