 In our [paper](https://arxiv.org/abs/2411.01493), we formalize LLM alignment as a **contextual dueling bandit (CDB)** problem (see illustration below) and propose a sample-efficient alignment approach based on Thompson sampling.

 The CDB framework necessitates an efficient online training system to validate the proposed method and compare it with other baselines. Oat 🌾 is developed as part of this research initiative.
 
 Using the CDB framework, existing LLM alignment paradigms can be summarized as follows:

 The benchmarking compares oat with the online DPO implementation from [huggingface/trl](https://huggingface.co/docs/trl/main/en/online_dpo_trainer). Below, we outline the configurations used for oat and present the benchmarking results. Notably, oat 🌾 achieves up to **2.5x** computational efficiency compared to trl 🤗.
