|
|
|
An initial foray into the world of fine-tuning. The goal of this release was to amplify the quality of the original model's responses, in particular for vision use cases* |

## Notes & Methodology |
|
* [Excalibur-7b](https://huggingface.co/InferenceIllusionist/Excalibur-7b) fine-tuned with Direct Preference Optimization (DPO) using Intel/orca_dpo_pairs |
|
* This is a quick experiment to determine the impact of DPO finetuning on the original base model |
|
* Ran for a little over an hour on a single A100 |
|
* Internal benchmarks showed improvement over base model, awaiting final results |
|
* Precision: bfloat16 |

|
|
|
*<b>Requires additional mmproj file. You have two options for vision functionality (available inside this repo):</b> |
|
* [Quantized - Limited VRAM Option (197mb)](https://huggingface.co/InferenceIllusionist/Excalibur-7b-DPO-GGUF/resolve/main/mistral-7b-mmproj-v1.5-Q4_1.gguf?download=true) |
|
* [Unquantized - Premium Option / Best Quality (596mb)](https://huggingface.co/InferenceIllusionist/Excalibur-7b-DPO-GGUF/resolve/main/mmproj-model-f16.gguf?download=true) |
|
|
|
Select the gguf file of your choice in [Koboldcpp](https://github.com/LostRuins/koboldcpp/releases/) as usual, then make sure to choose the mmproj file above in the LLaVA mmproj field of the model submenu: |

## Prompt Format |
|
* For best results please use ChatML for the prompt format. Alpaca may also work. |
