Implementation Details

We first followed the SimPO framework to apply On-Policy Preference Data Generation on the HuggingFaceH4/ultrafeedback_binarized dataset using the google/gemma-2-27b-it model. We then selected prompts where the chosen reward was at least 0.01 higher than the rejected reward, resulting in 37,040 training data points.

Model training was conducted using 8x80G A800 GPUs, leveraging the alignment-handbook library. We used deepspeed_zero_stage3 with optimizer offloading to the CPU. The SimPOTrainer arguments were as follows:

# SimPOTrainer arguments
