A Model Can Help Itself: Reward-Free Self-Training for LLM Reasoning

📰 ArXiv cs.AI

Researchers propose Self-evolving Post-Training (SePT), a method for improving LLM reasoning without external rewards

advanced Published 7 Apr 2026
Action Steps
  1. Sample questions using the LLM
  2. Generate low-temperature responses using the LLM
  3. Finetune the LLM on self-generated responses
  4. Repeat the process to improve reasoning performance
Who Needs to Know This

AI researchers and engineers can benefit from this method to improve their LLMs' reasoning capabilities without relying on external rewards or labeled data, which can be time-consuming and costly to obtain

Key Insight

💡 LLMs can self-train and improve their reasoning performance using their own sampled responses
