[P] RewardScope - reward hacking detection for RL training

"Reward hacking is a known problem but tooling for catching it is sparse. I built RewardScope to fill that gap. It wraps your environment and monitors reward components in real-time. Detects state cycling, component imbalance, reward spiking, and boundary exploitation. Everything streams to a live d..."

Increasing the Thinking Budget is Not All You Need

"Recently, a new wave of thinking-capable Large Language Models has emerged, demonstrating exceptional capabilities across a wide range of reasoning benchmarks. Early studies have begun to explore how the amount of compute in terms of the length of the reasoning process, the so-called thinking budget..."

Bottom-up Policy Optimization: Your Language Model Policy Secretly Contains Internal Policies

"Existing reinforcement learning (RL) approaches treat large language models (LLMs) as a single unified policy, overlooking their internal mechanisms. Understanding how policy evolves across layers and modules is therefore crucial for enabling more targeted optimization and raveling out complex reaso..."

GenEnv: Difficulty-Aligned Co-Evolution Between LLM Agents and Environment Simulators

"Training capable Large Language Model (LLM) agents is critically bottlenecked by the high cost and static nature of real-world interaction data. We address this by introducing GenEnv, a framework that establishes a difficulty-aligned co-evolutionary game between an agent and a scalable, generative e..."

Bohrium + SciMaster: Building the Infrastructure and Ecosystem for Agentic Science at Scale

"AI agents are emerging as a practical way to run multi-step scientific workflows that interleave reasoning with tool use and verification, pointing to a shift from isolated AI-assisted steps toward \emph{agentic science at scale}. This shift is increasingly feasible, as scientific tools and models c..."

MobileWorld: Benchmarking Autonomous Mobile Agents in Agent-User Interactive, and MCP-Augmented Environments

"Among existing online mobile-use benchmarks, AndroidWorld has emerged as the dominant benchmark due to its reproducible environment and deterministic evaluation; however, recent agents achieving over 90% success rates indicate its saturation and motivate the need for a more challenging benchmark. In..."

Can LLMs Predict Their Own Failures? Self-Awareness via Internal Circuits

"Large language models (LLMs) generate fluent and complex outputs but often fail to recognize their own mistakes and hallucinations. Existing approaches typically rely on external judges, multi-sample consistency, or text-based self-critique, which incur additional compute or correlate weakly with tr..."

Step-DeepResearch Technical Report

"As LLMs shift toward autonomous agents, Deep Research has emerged as a pivotal metric. However, existing academic benchmarks like BrowseComp often fail to meet real-world demands for open-ended research, which requires robust skills in intent recognition, long-horizon decision-making, and cross-sour..."

Emergent temporal abstractions in autoregressive models enable hierarchical reinforcement learning

"Large-scale autoregressive models pretrained on next-token prediction and finetuned with reinforcement learning (RL) have achieved unprecedented success on many problem domains. During RL, these models explore by generating new outputs, one token at a time. However, sampling actions token-by-token c..."

LongVideoAgent: Multi-Agent Reasoning with Long Videos

"Recent advances in multimodal LLMs and systems that use tools for long-video QA point to the promise of reasoning over hour-long episodes. However, many methods still compress content into lossy summaries or rely on limited toolsets, weakening temporal grounding and missing fine-grained cues. We pro..."
