SimPO aligns the reward function with the generation likelihood, eliminating the need for a reference model and incorporating a target reward margin to boost performance. Please refer to our [preprint](https://arxiv.org/pdf/2405.14734) and [github repo](https://github.com/princeton-nlp/SimPO) for more details. ## Model Details ### Model Description We fine-tuned [google/gemma-2-9b-it](https://huggingface.co./google/gemma-2-9b-it) on [princeton-nlp/gemma2-ultrafeedback-armorm](https://huggingface.co./datasets/princeton-nlp/gemma2-ultrafeedback-armorm) with the SimPO objective. - **Developed by:** Yu Meng, Mengzhou Xia, Danqi Chen - **Model type:** Causal Language Model - **License:** gemma - **Finetuned from model:** [google/gemma-2-9b-it](https://huggingface.co./google/gemma-2-9b-it) ### Model Sources - **Repository:** https://github.com/princeton-nlp/SimPO - **Paper:** https://arxiv.org/pdf/2405.14734 ## How to Get Started with the Model ``` import torch from transformers import pipeline model_id = "princeton-nlp/gemma-2-9b-it-SimPO" generator = pipeline( "text-generation", model=model_id, model_kwargs={"torch_dtype": torch.bfloat16}, device="cuda", ) outputs = generator([{"role": "user", "content": "What's the difference between llamas and alpacas?"}], do_sample=False, max_new_tokens=200) print(outputs[0]['generated_text']) ``` ## Training Details ### Training Data We use [princeton-nlp/gemma2-ultrafeedback-armorm](https://huggingface.co./datasets/princeton-nlp/gemma2-ultrafeedback-armorm) as the preference optimization dataset. #### Training Hyperparameters The hyperparameters used can be found in the [training script](https://github.com/princeton-nlp/SimPO/blob/main/training_configs/gemma-2-9b-it-simpo.yaml). #### Speeds, Sizes, Times Fine-tuning the [google/gemma-2-9b-it](https://huggingface.co./google/gemma-2-9b-it) on [princeton-nlp/gemma2-ultrafeedback-armorm](https://huggingface.co./datasets/princeton-nlp/gemma2-ultrafeedback-armorm) takes around 100 mins to finish on 8xH100 GPUs. ## Evaluation Results | models | AE2 LC | AE2 WR | AE2 Length | AH | AH Length | GSM | GSM Length | MMLU | MMLU Length | |-----------------------------------|:------:|:------:|:----------:|:----:|:---------:|:----:|:----------:|:----:|:-----------:| | [google/gemma-2-9b-it](https://huggingface.co./google/gemma-2-9b-it) | 51.1 | 38.1 | 1571 | 40.8 | 545 | 87.4 | 395 | 72.7 | 515 | | [princeton-nlp/gemma-2-9b-it-DPO](https://huggingface.co./princeton-nlp/gemma-2-9b-it-DPO) | 67.8 | 65.4 | 2016 | 58.9 | 717 | 88.5 | 392 | 72.2 | 624 | | [princeton-nlp/gemma-2-9b-it-SimPO](https://huggingface.co./princeton-nlp/gemma-2-9b-it-SimPO) | 72.4 | 65.9 | 1833 | 59.1 | 693 | 88.0 | 341 | 72.2 | 441 | ## Technical Specifications ### Model Architecture and Objective The model architecture is based on [google/gemma-2-9b-it](https://huggingface.co./google/gemma-2-9b-it). We use the SimPO training objective proposed in our [preprint](https://arxiv.org/pdf/2405.14734). #### Hardware We used 8xH100 GPUs for model training. #### Software Training was done using the [alignment-handbook](https://github.com/huggingface/alignment-handbook) library. ## Citation gemma model: ``` @article{gemma_2024, title={Gemma}, url={https://www.kaggle.com/m/3301}, DOI={10.34740/KAGGLE/M/3301}, publisher={Kaggle}, author={Gemma Team}, year={2024} } ``` SimPO paper: ``` @article{meng2024simpo, title={{SimPO}: Simple preference optimization with a reference-free reward}, author={Meng, Yu and Xia, Mengzhou and Chen, Danqi}, journal={arXiv preprint arXiv:2405.14734}, year={2024} } ``` UltraFeedback paper: ``` @article{cui2023ultrafeedback, title={{UltraFeedback}: Boosting language models with high-quality feedback}, author={Cui, Ganqu and Yuan, Lifan and Ding, Ning and Yao, Guanming and Zhu, Wei and Ni, Yuan and Xie, Guotong and Liu, Zhiyuan and Sun, Maosong}, journal={arXiv preprint arXiv:2310.01377}, year={2023} } ``` ArmoRM paper: ``` @article{wang2024interpretable, title={Interpretable Preferences via Multi-Objective Reward Modeling and Mixture-of-Experts}, author={Wang, Haoxiang and Xiong, Wei and Xie, Tengyang and Zhao, Han and Zhang, Tong}, journal={arXiv preprint arXiv:2406.12845}, year={2024} } ```
