Excalibur-7b-DPO-GGUF

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*

FP16 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 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

Sample Question - Vision

*Requires additional mmproj file. You have two options for vision functionality (available inside original repo or linked below):
