# Qwen3-8B β€” iMatrix GGUF
GGUF quantizations of [Qwen/Qwen3-8B](https://huggingface.co/Qwen/Qwen3-8B), published by [Liodon AI](https://huggingface.co/liodon-ai).
## Quick Start
**llama.cpp**
```bash
llama-cli -hf liodon-ai/Qwen3-8B-imatrix-GGUF:Q4_K_M
```
**Ollama**
```bash
ollama run hf.co/liodon-ai/Qwen3-8B-imatrix-GGUF:Q4_K_M
```
**LM Studio / Jan** β€” search `liodon-ai/Qwen3-8B-imatrix-GGUF` and pick your quant.
## Quants
| Quant | Size | VRAM est. | Notes |
|-------|------|-----------|-------|
| `IQ2_M` | 3.05 GB | ~4 GB | 2-bit, iMatrix β€” smallest usable |
| `IQ3_M` | 3.90 GB | ~4 GB | 3-bit, iMatrix β€” great quality/size tradeoff |
| `IQ4_XS` | 4.56 GB | ~5 GB | 4-bit extra-small, iMatrix |
| `Q4_K_M` | 5.03 GB | ~6 GB | 4-bit, iMatrix-calibrated (recommended) |
| `Q5_K_M` | 5.85 GB | ~7 GB | 5-bit, iMatrix-calibrated |
| `Q6_K` | 6.73 GB | ~8 GB | 6-bit, iMatrix-calibrated, near-lossless |
| `Q8_0` | 8.71 GB | ~10 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 β€”
**same file size, better output**.
Calibration: 2M tokens of [WikiText-103](https://huggingface.co/datasets/wikitext).
