When Non-Adversarial Noise Hurts Learning: Benchmarking Skill Self-Evolution in Agents

Large language model agents increasingly improve by distilling experience into reusable skills, but errors in that experience can persist in learned rules and affect later tasks. Existing evaluations largely examine clean learning or perturbations encountered after skills are frozen, leaving robustness during self-evol...

SearchMaster: Grounded and Regulated Self-Play for Search Agents

SearchMaster is presented, a self-play framework that trains a single LLM from search tasks it generates, solves, and verifies in a local search environment, showing that grounded and regulated self-play can provide effective search-agent training data without human-labeled QA pairs or expert demonstrations.

SearchAuditor: Auditing and Attributing Failures in Long-Horizon Search Agents

A benchmark that evaluates whether LLM auditors can localize, attribute, and repair search-agent failures through evidence-grounded adjudication, and proposes SearchAuditor, a multi-perspective auditing framework that effectively localizes, attributes, and repairs search-agent failures through evidence-grounded adjudic...

FailForge: Distilling Procedural Competence from Persistent Failures into Code Agents

FailForge is proposed, an agentic framework that converts failed rollouts into training signal, and recovers over 26% of previously failed instances at marginal additional cost, and training Qwen3.5-4B on the augmented corpus improves the SWE-bench Verified resolve rate by 6.6 points over a strong RFT baseline.

JoyAI-Talker: Full-Duplex Speech Interactive Large Model Built for Empathetic Voice Agents

We present JoyAI-Talker, a full-duplex speech dialogue system that delivers robust foundation model capabilities while empowering empathetic interaction and voice agent intelligence. JoyAI-Talker adopts a modular Thinker-Talker architecture and further implements a unified speech-text joint training pipeline to mitigat...
