CuratorMAS: Automating Dataset Curation via Multi-Agent Orchestration

CuratorMAS is a multi‑agent framework that automates dataset curation by orchestrating agents through five programmable stages: exploration, knowledge retrieval, criterion derivation, filtering, and evolution. It gathers contextual information, augments evaluation with online domain knowledge, computes metrics, filters data, and updates skills based on outcomes. Experiments show it can lower noise rates by up to 36.03 pp and boost downstream model F1 scores by up to 8.88 pp.

Auditable Claims about AI Agents

The paper "Auditable Claims about AI Agents" argues that for a claim about an AI agent to be verifiable, it must explicitly state the agent’s policy, scope, the records that would confirm the claim, and who is responsible for those records. It extends the Auditable Agents framework by adding conditions of independent record coverage, action‑specific authorization, and completeness beyond integrity, and demonstrates the approach with a claim‑check table applied to six common claims. The authors provide a worked example and practical guidance for operators, buyers, auditors, and standard setters.

Dynamic Budget Allocation for LLM Evaluation under Hard Resource Constraints

The paper introduces HARP, a hard-budget allocation method for evaluating large language models (LLMs) in multi-turn interactions where the time-to-event is partially observed due to resource limits. HARP guarantees that the total computational budget is never exceeded, reallocates unused budget, and provides lower predictive bounds (LPBs) with finite-sample coverage and unbiased metric estimates. Experiments on tasks such as jailbreaks, toxic content, and hallucinations demonstrate that HARP achieves near-nominal coverage with low variance while respecting the fixed budget.

Structured but Silent: Probing Capability Requirements in LLM Hidden States

The paper investigates whether large language models (LLMs) can infer the capability requirements of a user query before generating a response. Using the TACIT framework, the authors decompose these requirements into eight classes across three axes—Source, Transformation, and World Effect—and train linear probes on hidden states from four open-weight LLM families. Their results show that these capability structures are linearly decodable with high accuracy, yet the models struggle to express the same information in natural language, a phenomenon termed "structured but silent."

Rethinking Visual Provenance: Detection and Watermarking Across Direct Visual Generation and LLM-Driven Code Rendering

The paper proposes a production‑centered framework for comparing detection and watermarking techniques across two main AI image and video creation routes: direct visual generation and LLM‑driven code rendering. It introduces an explicit verification specification that separates passive inference, message recovery, and authenticated provenance, and organizes watermarks by production stage for images, videos, source code, and rendering‑aware outputs. The authors outline ten research questions covering identifiability, observability, fair comparison, payload recoverability, reconstruction, synchronization, composition, hybrid local contribution, and private production‑event authentication, and connect the framework to concrete systems such as Claude, OpenAI, and rendering tools.

FindIt: A Format-Informed Visual Detection Benchmark for Generalist Multimodal LLMs

The paper introduces FindIt, the first comprehensive benchmark for evaluating the promptable localization abilities of generalist multimodal large language models (MLLMs). It covers four core task categories—object detection, referring expression detection, instance-level detection, and video-based detection—and provides a unified framework that standardizes inputs, enforces parsable bounding box outputs, and defines transparent evaluation protocols. Using this benchmark, the authors assess a range of open-source and proprietary MLLMs, revealing both their strengths and limitations, particularly their sensitivity to formatting constraints and difficulty generalizing to minor variations.

Independent Multi-Agent Reinforcement Learning with Counterfactual Semantic-Social World Models

The paper introduces CASTLE, a framework for fully decentralized multi‑agent reinforcement learning that uses two offline‑trained world models to provide in‑context guidance to independent agents. A Local Dynamics World Model captures each agent’s trajectory dynamics, while a Semantic‑Social World Model predicts short‑horizon task and social outcomes for candidate actions based on counterfactual simulator rollouts. During online learning, these frozen models supply prediction logits to an independent PPO policy, enabling agents to compare potential actions prospectively rather than relying solely on scalar rewards. CASTLE outperforms existing baselines on several multi‑particle benchmark tasks, achieving the highest mean final scores across 30 seeds.
