Suzume ORPO

[Paper] [Dataset]

This is Suzume ORPO, an ORPO trained fine-tune of the lightblue/suzume-llama-3-8B-multilingual model using our lightblue/mitsu dataset.

We have trained several versions of this model using ORPO and so recommend that you use the best performing model from our tests, lightblue/suzume-llama-3-8B-multilingual-orpo-borda-half.

Note that this model has a non-commerical license as we used the Command R and Command R+ models to generate our training data for this model (lightblue/mitsu).

We are currently working on a developing a commerically usable model, so stay tuned for that!

Model list

We have ORPO trained the following models using different proportions of the lightblue/mitsu dataset:

• Trained on the top/bottom responses of all prompts in the dataset: lightblue/suzume-llama-3-8B-multilingual-orpo-borda-full
• Trained on the top/bottom responses of the prompts of the 75% most consistently ranked responses in the dataset: lightblue/suzume-llama-3-8B-multilingual-orpo-borda-top75
• Trained on the top/bottom responses of the prompts of the 50% most consistently ranked responses in the dataset: lightblue/suzume-llama-3-8B-multilingual-orpo-borda-half
• Trained on the top/bottom responses of the prompts of the 25% most consistently ranked responses in the dataset: lightblue/suzume-llama-3-8B-multilingual-orpo-borda-top25

Model results

We compare the MT-Bench scores across 6 languages for our 4 ORPO trained models, as well as some baselines:

• meta-llama/Meta-Llama-3-8B-Instruct - The foundation model that our models are ultimately built upon
• Nexusflow/Starling-LM-7B-beta - The highest performing open model on the Chatbot arena that is of a similar size to ours
• gpt-3.5-turbo - A fairly high quality (although not state-of-the-art) proprietary LLM
• lightblue/suzume-llama-3-8B-multilingual - The base model which we train our ORPO finetunes from

We can see noticable improvement on most languages compared to the base model. We also find that our ORPO models achieve the highest score out of all the models we evaluated for a number of languages.

Training data

We trained this model using the lightblue/mitsu_full_borda dataset.
