Good SFT Optimizes for SFT, Better SFT Prepares for Reinforcement Learning

Dylan Zhang, Yufeng Xu, Haojin Wang +2

Post-training of reasoning LLMs is a holistic process that typically consists of an offline SFT stage followed by an online reinforcement learning (RL) stage. However, SFT is often…

The Best Instruction-Tuning Data are Those That Fit

Dylan Zhang, Qirun Dai, Hao Peng

High-quality supervised fine-tuning (SFT) data are crucial for eliciting strong capabilities from pretrained large language models (LLMs). Typically, instructions are paired with m…

Improving Influence-based Instruction Tuning Data Selection for Balanced Learning of Diverse Capabilities

Qirun Dai, Dylan Zhang, Jiaqi W. Ma +1

Selecting appropriate training data is crucial for instruction fine-tuning of large language models (LLMs), which aims to (1) elicit strong capabilities, and (2) achieve balanced p…

: Improving Code LMs with Execution-Guided On-Policy Preference Learning Driven By Synthetic Test Cases

Dylan Zhang, Shizhe Diao, Xueyan Zou +1

Preference learning provides a promising solution to address the limitations of supervised fine-tuning (SFT) for code language models, where the model is not explicitly trained to…
