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-Q8_0 | 0.5 | multi-modal supplement |
| GGUF | mmproj-f16 | 0.8 | multi-modal supplement |
| GGUF | Q2_K | 2.2 | |
| GGUF | Q3_K_S | 2.4 | |
| GGUF | Q3_K_M | 2.6 | lower quality |
| GGUF | Q3_K_L | 2.8 | |
| GGUF | IQ4_XS | 3.0 | |
| GGUF | Q4_K_S | 3.0 | fast, recommended |
| GGUF | Q4_K_M | 3.2 | fast, recommended |
| GGUF | Q5_K_S | 3.5 | |
| GGUF | Q5_K_M | 3.6 | |
| GGUF | Q6_K | 4.1 | very good quality |
| GGUF | Q8_0 | 5.3 | fast, best quality |
| GGUF | f16 | 9.8 | 16 bpw, overkill |

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.
