HAServe: Horizon-Aware Scheduling and Memory Co-Design for Efficient LLM Serving

HAServe is presented, which turns HorizonSchema, a workload abstraction that connects exact prefix paths, permitted serializations, and released consumers as shared inputs to both decisions, into a scheduling--memory co-design method of systematic optimization for online LLM serving.

STEPS: Selective On-Policy Self-Distillation for Reasoning

STEPS is proposed, a selective OPSD framework that controls the location, direction, and duration of distillation that improves mean accuracy over GRPO and support brief, targeted self-distillation as an efficient complement to reward-driven reasoning training.

Mitigating Exploration Bias in RL for Multi-Instruction Following

Two metrics to measure the exploration bias in instruction following are proposed and a two-stage framework to alleviate it is introduced: Behavioral Bootstrapping, a lightweight rejection sampling fine-tuning stage before RL to activate hard instructions; and Scarcity-Aware Rewards, a new RL reward function that assig...

CacheBridge: Efficient Cross-Model KV Cache Transfer

CacheBridge is introduced, which co-designs architecture-indexed mapper support, attention-aligned calibration, and bounded mapper construction while retaining a closed-form affine interface for online deployment.
