Excalibur-7b-DPO

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*

Weighted (Importance Matrix) Quants available here

Static (Legacy) quants available here

Notes & Methodology

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 Excelsior-7b base model
Ran for a little over an hour on a single A100
Fine-tuning succeeded in making model conversational and more well-rounded
Benchmark scores increased in the following categories versus base Excelsior-7b:
- ARC: 69.71 -> 70.9
- HellaSwag: 87.56 -> 87.93
- TruthfulQA: 67.24 -> 70.82
- Average: 73.6 -> 73.84
Precision: bfloat16

Sample Question - Vision

*Requires additional mmproj file. You have two options for vision functionality (available inside this repo):

Select the gguf file of your choice in Koboldcpp 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.
