Reinforcement Learning for LLM Post-Training: A Survey

Zhichao Wang, Kiran Ramnath, Bin Bi +9

Large language models (LLMs) trained via pretraining and supervised fine-tuning (SFT) can still produce harmful and misaligned outputs, or struggle in domains like math and coding.…

UFT: Unifying Fine-Tuning of SFT and RLHF/DPO/UNA through a Generalized Implicit Reward Function

Zhichao Wang, Bin Bi, Zixu Zhu +6

By pretraining on trillions of tokens, an LLM gains the capability of text generation. However, to enhance its utility and reduce potential harm, SFT and alignment are applied sequ…
