For a convenient overview and download list, visit our model page for this model.
static quants are available at https://huggingface.co/mradermacher/gemma-4-12B-it-qat-q4_0-unquantized-uncensored-heretic-v3-GGUF
This is a vision model - mmproj files (if any) will be in the static repository.
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 | 3.1 | for the desperate |
| GGUF | i1-IQ1_M | 3.3 | mostly desperate |
| GGUF | i1-IQ2_XXS | 3.7 | |
| GGUF | i1-IQ2_XS | 4.0 | |
| GGUF | i1-IQ2_S | 4.2 | |
| GGUF | i1-IQ2_M | 4.5 | |
| GGUF | i1-Q2_K_S | 4.6 | very low quality |
| GGUF | i1-Q2_K | 4.9 | IQ3_XXS probably better |
| GGUF | i1-IQ3_XXS | 4.9 | lower quality |
| GGUF | i1-IQ3_XS | 5.4 | |
| GGUF | i1-IQ3_S | 5.6 | beats Q3_K* |
| GGUF | i1-Q3_K_S | 5.6 | IQ3_XS probably better |
| GGUF | i1-IQ3_M | 5.8 | |
| GGUF | i1-Q3_K_M | 6.2 | IQ3_S probably better |
| GGUF | i1-Q3_K_L | 6.7 | IQ3_M probably better |
| GGUF | i1-IQ4_XS | 6.7 | |
| GGUF | i1-IQ4_NL | 7.1 | prefer IQ4_XS |
| GGUF | i1-Q4_0 | 7.1 | fast, low quality |
| GGUF | i1-Q4_K_S | 7.1 | optimal size/speed/quality |
| GGUF | i1-Q4_K_M | 7.5 | fast, recommended |
| GGUF | i1-Q4_1 | 7.8 |

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.
