Quants
| Quant | Size | VRAM est. | Notes |
|---|---|---|---|
IQ2_M | 1.51 GB | ~2 GB | 2-bit, iMatrix — smallest usable |
IQ3_M | 1.96 GB | ~2 GB | 3-bit, iMatrix — great quality/size tradeoff |
IQ4_XS | 2.27 GB | ~3 GB | 4-bit extra-small, iMatrix |
Q4_K_M | 2.50 GB | ~3 GB | 4-bit, iMatrix-calibrated (recommended) |
Q5_K_M | 2.89 GB | ~3 GB | 5-bit, iMatrix-calibrated |
Q6_K | 3.31 GB | ~4 GB | 6-bit, iMatrix-calibrated, near-lossless |
Q8_0 | 4.28 GB | ~5 GB | 8-bit, essentially lossless |
What is iMatrix?
Standard quantization treats all weights equally. iMatrix runs 128 calibration chunks through the full-precision model to find which weights matter most, then allocates more precision where it counts. At Q2/Q3/Q4 this means noticeably better coherence and instruction-following — same file size, better output.
Calibration: 2M tokens of WikiText-103.
