About

weighted/imatrix quants of https://huggingface.co/v000000/Qwen2.5-Lumen-14B

static quants are available at https://huggingface.co/mradermacher/Qwen2.5-Lumen-14B-GGUF

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	i1-IQ1_S	3.7	for the desperate
GGUF	i1-IQ1_M	4.0	mostly desperate
GGUF	i1-IQ2_XXS	4.4
GGUF	i1-IQ2_XS	4.8
GGUF	i1-IQ2_S	5.1
GGUF	i1-IQ2_M	5.5
GGUF	i1-Q2_K	5.9	IQ3_XXS probably better
GGUF	i1-IQ3_XXS	6.0	lower quality
GGUF	i1-IQ3_XS	6.5
GGUF	i1-Q3_K_S	6.8	IQ3_XS probably better
GGUF	i1-IQ3_S	6.8	beats Q3_K*
GGUF	i1-IQ3_M	7.0
GGUF	i1-Q3_K_M	7.4	IQ3_S probably better
GGUF	i1-Q3_K_L	8.0	IQ3_M probably better
GGUF	i1-IQ4_XS	8.2
GGUF	i1-Q4_0_4_4	8.6	fast on arm, low quality
GGUF	i1-Q4_0_4_8	8.6	fast on arm+i8mm, low quality
GGUF	i1-Q4_0_8_8	8.6	fast on arm+sve, low quality
GGUF	i1-Q4_0	8.6	fast, low quality
GGUF	i1-Q4_K_S	8.7	optimal size/speed/quality
GGUF	i1-Q4_K_M	9.1	fast, recommended
GGUF	i1-Q5_K_S	10.4
GGUF	i1-Q5_K_M	10.6
GGUF	i1-Q6_K	12.2	practically like static Q6_K

Thanks

I thank my company, nethype GmbH, for letting me use its servers and providing upgrades to my workstation to enable this work in my free time. Additional thanks to @nicoboss for giving me access to his private supercomputer, enabling me to provide many more imatrix quants, at much higher quality, than I would otherwise be able to.
