About

static quants of https://huggingface.co/ValiantLabs/gemma-4-12B-it-Esper4

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

weighted/imatrix quants are available at https://huggingface.co/mradermacher/gemma-4-12B-it-Esper4-i1-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	mmproj-f16	0.2	multi-modal supplement
GGUF	mmproj-Q8_0	0.3	multi-modal supplement
GGUF	Q2_K	4.9
GGUF	Q3_K_S	5.6
GGUF	Q3_K_M	6.2	lower quality
GGUF	Q3_K_L	6.7
GGUF	IQ4_XS	6.8
GGUF	Q4_K_S	7.1	fast, recommended
GGUF	Q4_K_M	7.5	fast, recommended
GGUF	Q5_K_S	8.4
GGUF	Q5_K_M	8.6
GGUF	Q6_K	9.9	very good quality
GGUF	Q8_0	12.8	fast, best quality

Here is a handy graph by ikawrakow comparing some lower-quality quant types (lower is better):
