Playing social deduction games with reinforcement fine-tuned large language models

Reinforcement fine-tuning (RFT) is increasingly used in applications where large language models (LLMs) interact with humans and other agents. Here we use social deduction games to study how RFT changes LLMs'social behaviour. We let fine-tuned and base LLM agents play hidden-role games that require hidden-state inferen...

RLCSD: Reinforcement Learning with Contrastive On-Policy Self-Distillation

This work proposes RLCSD (Reinforcement Learning with Contrastive on-policy Self-Distillation), which mitigates this drift by contrasting the teacher-student gap under a correct hint against that under a wrong hint, suppressing style shifts induced by hints regardless of correctness and yielding a signal more concentra...
