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.
