GraphOPD: Graph-Augmented On-Policy Distillation for LLM Agents

On-policy distillation post-trains large language model agents by supplying dense, step-level guidance from a teacher policy when the reinforcement-learning reward is sparse and arrives only once per trajectory. Existing instantiations allocate this guidance by the size of the teacher-student divergence at each step, o...

RING: Retrieval-Internalized Generation for Continual Large-Scale Knowledge Injection

RING (Retrieval-Internalized Generation), a holistic paradigm spanning both architecture and training that injects large-scale external knowledge into aixture-of-Memory Experts and learns parametric search over this internal memory via reinforcement learning, removing the external retriever entirely, is proposed.
