ARISE: Adapting to Evolving Capability Gaps in Agentic Reinforcement Learning

Kun Feng, Yuchen Fang, Yiyang Tan, Shuqi Gu, Yongxiang Zhao

RISE addresses the challenge of evolving capability gaps in long-horizon reinforcement learning agents. Its core method, Adaptive Rubric-Skill Co-Evolution (ARISE), continuously adapts evaluation criteria and exploration strategies based on agent performance. This allows the agent to focus learning on emerging weaknesses and make progress even with sparse task-level feedback.

Continuous Context Management

William Hoy, Jingxuan Fan et al.

This paper introduces Continuous Context Management (CCM) for LLM agents, which compacts interaction history at every turn instead of waiting for a threshold. This prevents the active prompt from growing excessively, significantly reducing input usage and prom…

KV-streams for Efficient Compaction in Agentic Reinforcement Learning

Emiliano Penaloza, Dane Malenfant et al.

This paper introduces KV-streams, a novel method to improve the efficiency of context compaction in agentic reinforcement learning. Instead of repeatedly refilling the LLM's context, KV-streams stream the KV cache forward, significantly boosting training throu…

SEABench: Benchmarking Endogenous Misalignment In Self-Evolving Agents

Saswat Das, Parvati Viswanathan et al.

This paper introduces SEABench, a novel benchmark designed to evaluate "endogenous misalignment" in self-evolving AI agents. The core method involves creating longitudinal task sequences in a personal assistant environment to observe how agents' self-modificat…

TokenCast: Forecasting Token Consumption During LLM Agent Execution

Chaoqian Ouyang, Ling Yue et al.

TokenCast addresses the unpredictable token consumption of LLM agents by learning a composable cost representation for execution segments. This method estimates future token usage by accounting for both segment-specific consumption and the context growth intro…

Rethinking Personalized Generation: Test-Time Alignment via Factorized Ranking Models

Qiyao Ma, Junshan Zhang et al.

This paper proposes a test-time alignment method for personalized generation with LLMs. It argues that personalization is a candidate matching problem, not a generator limitation, …
