Navalia: Advancing Cowork Agents through Verifiable Task Synthesis and Long-Horizon Post-Training

Hengqi Liu, Ziyuan Liu, Yang Qin +7

Large language model (LLM) agents are evolving from conversational assistants into Cowork Agents capable of autonomous planning, tool use, and complex task execution. Financial ana…

AdaptEvo: Learning under Imperfect Supervision through Confidence-Adaptive Training with Knowledge Evolution

AllSpark Team, Shijun Wan, Jiancong Xie +8

Rule-governed contextual decision tasks require models to apply specified rules to case-specific context and evidence. Written rules can leave gaps in decision guidance and process…

ROSS: Relearning from Self-Generated Rollouts through Selective Supervision

Zhiwei Zhang, Huayu Deng, Fei Zhao +4

Large language model post-training generates self-generated rollouts through reinforcement learning and on-policy distillation, yet this experience is often treated as stale once t…

Skill2Env: Capability-Oriented Environment Synthesis from Skills for General Agents

Weiyi Xu, Xiaowen Yang, Wen Da +7

Executable environments are critical for post-training agents on tasks that require tool use and multi-step interaction, but constructing executable tasks together with their envir…

CompoWorld: Compositional Environment Scaling for General Agents

Xiao-Wen Yang, Weiyi Xu, Wen Da +9

Automatically generated environments provide a scalable source of interaction data for training general agents. However, existing approaches mainly generate tasks within a single e…

Learning to Learn from Context: Synthetic Training from Perturbed Public Documents

Haoyi Wu, Yang Xiao, Yusong Sun +4

Real-world tasks often require large language models (LLMs) to learn from complex task-specific context rather than pretrained parametric knowledge. This capability remains a weakn…

PACT: From Credit Assignment to Critic Alignment

Jiayan Fu, Hang Xu, Yong Zhang +4

Reinforcement learning has become a central component of large language model (LLM) post-training, yet token-level credit lacks a generally accepted mathematical definition, leavin…

NoteVQA: Benchmarking VLMs on Real-Life Questions from Human Communities

Haonan Jiang, Guojian Zhan, Jiancong Xie +6

Vision-language models (VLMs) increasingly power consumer-facing AI search, yet evaluating them on the diversity of everyday visual questions remains challenging. Existing benchmar…

Iris: Climbing to the Search Frontier

Ziyuan Liu, Hengqi Liu, Zichuan Wang +8

We present Iris-mini and Iris-pro, two search agents trained at the 35B-A3B and 397B-A17B scales, together with the data pipeline and training recipe behind them. Tasks are reverse…

Verify Before You Distill: Prompt-Level Teacher Gating for On-Policy Distillation

Zhiwei Zhang, Zechen Sun, Fei Zhao +6

On-policy distillation (OPD) accelerates post-training by providing dense token-level supervision from a frozen teacher on the student's own rollouts. Vanilla OPD applies this supe…

PILOT in the Loop: Live Self-Improvement for Long-Horizon Agents

Yang Xiao, Yusong Sun, Haoyi Wu +7

Long-horizon agent runs generate experience that can improve both the current run and future work. Most self-improvement methods process this experience only after execution ends,…

D-MOPD: Dynamic Domain ScheDuling for Efficient Multi-Teacher Distillation

Zechen Sun, Zhiwei Zhang, Fei Zhao +7

Multi-teacher on-policy distillation (MOPD) distills several domain-expert teachers into a single student by minimizing per-domain reverse-KL divergence on the student's own rollou…
