This repository contains the exl2 quants of [karakuri-ai/karakuri-lm-70b-v0.1](https://huggingface.co/karakuri-ai/karakuri-lm-70b-v0.1), calibrated using [the default dataset built by exllamav2](https://github.com/turboderp/exllamav2/blob/3b0f5230e9619fc0ddf1f302785049d10a65fe26/conversion/tokenize.py#L55).

Compatible with [exllamav2](https://github.com/turboderp/exllamav2) version 0.0.11 and later. For optimal model loading, it is recommended to use [tabbyAPI](https://github.com/theroyallab/tabbyAPI).

The measurement file is attached in the branch `main` and all quants are stored in their respective branches.

The chart below presents the calibration perplexity and [wikitext-103-v1](https://huggingface.co/datasets/wikitext) test perplexity for all provided quants.

*: This first 2.65bpw-h6 quantized version has been deprecated due to unexpectedly high wikitext-103-v1 Test Perplexity values.
