ORPO

`Updates (24.03.25)`

Sample script for ORPOTrainer in 🤗TRL is added to trl/test_orpo_trainer_demo.py
New model, 🤗kaist-ai/mistral-orpo-capybara-7k, is added to 🤗ORPO Collection
Now you can try ORPO in 🤗TRL and Axolotl🔥
We are making general guideline for training LLMs with ORPO, stay tuned🔥
Mistral-ORPO-β achieved a 14.7% in the length-controlled (LC) win rate on official AlpacaEval Leaderboard🔥

This is the official repository for ORPO: Monolithic Preference Optimization without Reference Model. The detailed results in the paper can be found in:

`Model Checkpoints`

Our models trained with ORPO can be found in:

Mistral-ORPO-Capybara-7k: 🤗 kaist-ai/mistral-orpo-capybara-7k
Mistral-ORPO-⍺: 🤗 kaist-ai/mistral-orpo-alpha
Mistral-ORPO-β: 🤗 kaist-ai/mistral-orpo-beta

And the corresponding logs for the average log probabilities of chosen/rejected responses during training are reported in:

Mistral-ORPO-Capybara-7k: TBU
Mistral-ORPO-⍺: Wandb Report for Mistral-ORPO-⍺
Mistral-ORPO-β: Wandb Report for Mistral-ORPO-β

`AlpacaEval`

`MT-Bench`

`IFEval`

IFEval scores are measured with EleutherAI/lm-evaluation-harness by applying the chat template. The scores for Llama-2-Chat (70B), Zephyr-β (7B), and Mixtral-8X7B-Instruct-v0.1 are originally reported in this tweet.
