About
weighted/imatrix quants of https://huggingface.co/AstroMLab/AstroSage-8B
static quants are available at https://huggingface.co/mradermacher/AstroSage-8B-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 | 2.1 | for the desperate |
| GGUF | i1-IQ1_M | 2.3 | mostly desperate |
| GGUF | i1-IQ2_XXS | 2.5 | |
| GGUF | i1-IQ2_XS | 2.7 | |
| GGUF | i1-IQ2_S | 2.9 | |
| GGUF | i1-IQ2_M | 3.0 | |
| GGUF | i1-Q2_K | 3.3 | IQ3_XXS probably better |
| GGUF | i1-IQ3_XXS | 3.4 | lower quality |
| GGUF | i1-IQ3_XS | 3.6 | |
| GGUF | i1-Q3_K_S | 3.8 | IQ3_XS probably better |
| GGUF | i1-IQ3_S | 3.8 | beats Q3_K* |
| GGUF | i1-IQ3_M | 3.9 | |
| GGUF | i1-Q3_K_M | 4.1 | IQ3_S probably better |
| GGUF | i1-Q3_K_L | 4.4 | IQ3_M probably better |
| GGUF | i1-IQ4_XS | 4.5 | |
| GGUF | i1-Q4_0_4_4 | 4.8 | fast on arm, low quality |
| GGUF | i1-Q4_0_4_8 | 4.8 | fast on arm+i8mm, low quality |
| GGUF | i1-Q4_0_8_8 | 4.8 | fast on arm+sve, low quality |
| GGUF | i1-Q4_0 | 4.8 | fast, low quality |
| GGUF | i1-Q4_K_S | 4.8 | optimal size/speed/quality |
| GGUF | i1-Q4_K_M | 5.0 | fast, recommended |
| GGUF | i1-Q5_K_S | 5.7 | |
| GGUF | i1-Q5_K_M | 5.8 | |
| GGUF | i1-Q6_K | 6.7 | 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.
