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*

GGUFs 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):

• Quantized - Limited VRAM Option (197mb)
• Unquantized - Premium Option / Best Quality (596mb)

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.
