About

weighted/imatrix quants of https://huggingface.co/DavidAU/LFM2.5-1.2B-Instruct-Thinking-Claude-High-Reasoning

For a convenient overview and download list, visit our model page for this model.

static quants are available at https://huggingface.co/mradermacher/LFM2.5-1.2B-Instruct-Thinking-Claude-High-Reasoning-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	imatrix	0.1	imatrix file (for creating your own quants)
GGUF	i1-IQ1_S	0.4	for the desperate
GGUF	i1-IQ1_M	0.4	mostly desperate
GGUF	i1-IQ2_XXS	0.5
GGUF	i1-IQ2_XS	0.5
GGUF	i1-IQ2_S	0.5
GGUF	i1-IQ2_M	0.5
GGUF	i1-Q2_K_S	0.6	very low quality
GGUF	i1-Q2_K	0.6	IQ3_XXS probably better
GGUF	i1-IQ3_XXS	0.6	lower quality
GGUF	i1-IQ3_XS	0.6
GGUF	i1-IQ3_S	0.7	beats Q3_K*
GGUF	i1-Q3_K_S	0.7	IQ3_XS probably better
GGUF	i1-IQ3_M	0.7
GGUF	i1-Q3_K_M	0.7	IQ3_S probably better
GGUF	i1-Q3_K_L	0.7	IQ3_M probably better
GGUF	i1-IQ4_XS	0.8
GGUF	i1-IQ4_NL	0.8	prefer IQ4_XS
GGUF	i1-Q4_0	0.8	fast, low quality
GGUF	i1-Q4_K_S	0.8	optimal size/speed/quality
GGUF	i1-Q4_K_M	0.8	fast, recommended
GGUF	i1-Q4_1	0.9
GGUF	i1-Q5_K_S	0.9
GGUF	i1-Q5_K_M	0.9
GGUF	i1-Q6_K	1.1	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.
