# Wizard-LM-2-8x22-iMat-GGUF


Quantized from fp32 with love. If you're using the latest version of llama.cpp you should no longer need to combine files before loading.
* Importance matrix calculated using fp16 precision model
* Calculated in 105 chunks with n_ctx=512 using groups_merged.txt
* See below for imatrix calculation arguments

```
.\llama-imatrix -m .\models\WizardLM-2-8x22b\ggml-model-f16.gguf -f  .\imatrix\groups_merged.txt -o .\models\WizardLM-2-8x22b\WizardLM-2-8x22b-f16.imatrix -ngl 14 -t 24
```

For a brief rundown of iMatrix quant performance please see this [PR](https://github.com/ggerganov/llama.cpp/pull/5747)

<i>All quants are verified working prior to uploading to repo for your safety and convenience. </i>


<b>Tip:</b> Pick a size that can fit in your GPU while still allowing some room for context for best speed. You may need to pad this further depending on if you are running image gen or TTS as well.
