SEAR: Self-Evolving Agentic Robotics

"Frontier language-model agents can now improve robots on their own: they write control code, test it, and keep what works as skills and memories for the next task. We introduce SEAR (Self-Evolving Agentic Robotics), a framework and benchmark built around two questions. Is the agent really learning,..."

Scaling Discovery Requires Forgetting

Beyond LLM Judge: Mechanical Verification for Agentic Autoformalization

Co-Evolving Acting and Forecasting for Language Agents

Prior work exploits this supervision through value targets tha..."

MolLean: A Process-Verifiable Language for Chemical Reasoning

Who Improves the Robot? Toward Physical Recursive Self-Improvement

This study investigates Physical Recursive Self-Improvement (Physical RSI), in which physical experience guides lasting updates to both a robot's capabilities and its improvement procedure, maki..."

The COUNT: Counting N-grams Unlocks Scaling on Host Memory and Training-Free Adaptation

"The scaling relationship of compute and performance for language models (LMs) has been extensively studied; more recently, models are being designed to scale memory use, as well. In particular, adding embeddings for n-grams scales memory separately from compute use, because each pass only processes..."

PrismaCoder: Pushing the Boundaries of Open Multimodal Code Intelligence through Decomposed Rubric Synthesis

Interest in this capability is burgeoning, as models are increasingly asked to produce charts, webpages, animations, and semi-structured documents. Recently, proprietary models have pu..."

BLADE: Auditing Information Use for Failure Attribution in LLM Multi-Agent Systems

"Large language model multi-agent systems extend individual agents' capabilities through collaboration across specialized roles, tools, and workflows.

SkillScaffold: Scaffolding Agentic Reinforcement Learning with Policy-Adaptive Skill Credit Assignment and Selective Injection

"Agentic reinforcement learning (RL) enables large language models (LLMs) to learn from multi-turn interactions with verifiable outcomes. Textual skills can improve exploration by distilling prior interactions into reusable guidance. However, existing skill-based RL approaches often either assume ski..."

The Last Remote Sensing Model Built by Humans? Casting Any Earth Observation Task as Recursive Self-Improvement

"Earth observation (EO) models are still built by hand. For each new task, experts design a training recipe and tune it against a benchmark. We show that this loop can be handed to an agent. Any verifiable task can be cast as a harness and a verifier, where the harness defines what the agent may use..."

Tev: Scaling Long-Horizon Agentic Environments with Dense Progress Rewards

"Long-horizon agents have drawn growing attention for their ability to work autonomously -- from hours to days -- on economically valuable tasks, a capability essential to automated discovery and recursive self-improvement (RSI). Yet open-source models still struggle on long-horizon tasks, largely fo..."

AdaRSI: On-Demand Recursive Self-Improvement for Embodied Agents

"Pretrained vision-language-action models (VLAs) often fail midway through unseen long-horizon tasks. Recursive self-improvement (RSI) offers a remedy, but embodied RSI methods either refine the harness around a frozen executor and so cannot add a missing motion, or train the executor on persistent f..."

One Task, Many Interfaces: Simple Cross-Interface Consistency Training Improves LLM Agent Robustness

"Post-training binds the competence of an LLM agent to the interface it was trained on. Semantics-preserving perturbations of that interface, such as renaming an action or changing the notation, leave the underlying task unchanged yet make the agent worse at it. Scoring each sample independently mean..."

Pack Light, CarryOn: Building Object-Oriented Context for Long-Horizon Agents

"Long-horizon agents accumulate progress in persistent task state, yet repeatedly process interaction histories describing how that progress was achieved. This raises a natural question: can long-horizon context instead be organized around reusable progress rather than the history that produced it? I..."

Hybrid Reasoning Agents

Same Claim, Different Interpretations: How LLM Agents Resolve Ambiguity in Scientific Claims

"Co-scientists and agentic scientific claim verifiers are increasingly used to assess claims across the sciences. Natural-language scientific claims, written for human experts, are often underspecified and so admit several defensible interpretations. Such verifiers usually pick one, often tacitly, an..."

ActiveEvidence: Decision-Focused Evidence Graphs with Verifiable Acquisition Gaps

We study this problem under a strict free-metadata/paid-observation boundary, stochastic vector costs, and a frozen execu..."

Rubrics from the Task, Verdicts from Evidence: Pointwise Rubric Rewards with Tool-Augmented Judges

However, existing methods often derive criteria from observed response candidates, introducing response-induced bias that may limit rubric generalizability. Their judges also struggle with mechanical constraints when rely..."

ChunkAct: Action Chunking for Agentic Robotics

"Agentic robotics places a large language model (LLM) agent in the robot control loop, where it composes perception, motion, and vision-language-action (VLA) tools under the guidance of a memory and thereby generalizes to new tasks without retraining. This generality comes at a steep price in efficie..."

Recovering Reliable Supervision via Critique-Guided On-Policy Distillation

We call this property the recoverability of the teacher and show it fails on incorrect rollout..."

DoubtLess: Training-Free Contrastive Decoding for Efficient Reasoning
