We have used our own OpenOrca dataset to fine-tune on top of Mistral 7B.
This dataset is our attempt to reproduce the dataset generated for Microsoft Research's Orca Paper.
We use OpenChat packing, trained with Axolotl.
This release is trained on a curated filtered subset of most of our GPT-4 augmented data.
It is the same subset of our data as was used in our OpenOrcaxOpenChat-Preview2-13B model.
HF Leaderboard evals place this model as #2 for all models smaller than 30B at release time, outperforming all but one 13B model.
This release provides a first: a fully open model with class-breaking performance, capable of running fully accelerated on even moderate consumer GPUs.
Our thanks to the Mistral team for leading the way here.
We affectionately codename this model: "MistralOrca"
This means that, e.g., in oobabooga the "MPT-Chat" instruction template should work, as it also uses ChatML.

We have evaluated using the methodology and tools for the HuggingFace Leaderboard, and find that we have dramatically improved upon the base model.
We find 105% of the base model's performance on HF Leaderboard evals, averaging 65.33.
At release time, this beats all 7B models, and all but one 13B.

We use Language Model Evaluation Harness to run the benchmark tests above, using the same version as the HuggingFace LLM Leaderboard.
AGIEval Performance
We compare our results to the base Mistral-7B model (using LM Evaluation Harness).
We find 129% of the base model's performance on AGI Eval, averaging 0.397.
As well, we significantly improve upon the official mistralai/Mistral-7B-Instruct-v0.1 finetuning, achieving 119% of their performance.

BigBench-Hard Performance
We find 119% of the base model's performance on BigBench-Hard, averaging 0.416.

Dataset
We used a curated, filtered selection of most of the GPT-4 augmented data from our OpenOrca dataset, which aims to reproduce the Orca Research Paper dataset.
Training
We trained with 8x A6000 GPUs for 62 hours, completing 4 epochs of full fine tuning on our dataset in one training run.
Commodity cost was ~$400.
