SPELL: Self-Play Reinforcement Learning for Evolving Long-Context Language Models

Ziyi Yang, Weizhou Shen, Chenliang Li +5

Progress in long-context reasoning for large language models (LLMs) has lagged behind other recent advances. This gap arises not only from the intrinsic difficulty of processing lo…
