Self-Play Only Evolves When Self-Synthetic Pipeline Ensures Learnable Information Gain

Wei Liu, Siya Qi, Yali Du +1

Large language models (LLMs) make it plausible to build systems that improve through self-evolving loops, but many existing proposals are better understood as self-play and often p…

Hunt Instead of Wait: Evaluating Deep Data Research on Large Language Models

Wei Liu, Peijie Yu, Michele Orini +2

The agency expected of Agentic Large Language Models goes beyond answering correctly, requiring autonomy to set goals and decide what to explore. We term this investigatory intelli…

Calibrate-Then-Delegate: Safety Monitoring with Risk and Budget Guarantees via Model Cascades

Edoardo Pona, Milad Kazemi, Mehran Hosseini +4

Monitoring LLM safety at scale requires balancing cost and accuracy: a cheap latent-space probe can screen every input, but hard cases should be escalated to a more expensive exper…

CODI: Compressing Chain-of-Thought into Continuous Space via Self-Distillation

Zhenyi Shen, Hanqi Yan, Linhai Zhang +3

Chain-of-Thought (CoT) reasoning enhances Large Language Models (LLMs) by encouraging step-by-step reasoning in natural language. However, leveraging a latent continuous space for…

NOVER: Incentive Training for Language Models via Verifier-Free Reinforcement Learning

Wei Liu, Siya Qi, Xinyu Wang +3

Recent advances such as DeepSeek R1-Zero highlight the effectiveness of incentive training, a reinforcement learning paradigm that computes rewards solely based on the final answer…
