RAM by quantization
Lower quantization = less RAM but lower quality. Q4_K_M is the recommended sweet spot for most users.
| Format | Bits | RAM | Quality | Verdict |
|---|---|---|---|---|
| Q3_K_M | 3 | 7.0 GB | Moderate | Runs great |
| Q4_K_MREC | 4 | 8.7 GB | Good | Runs great |
| Q5_K_M | 5 | 10.4 GB | Good | Runs great |
| Q6_K | 6 | 11.6 GB | Excellent | Runs great |
| Q8_0 | 8 | 15.0 GB | Excellent | Runs OK |
| F16 | 16 | 28.6 GB | Lossless | After cleanup |
