StreamOPD: A Post-Training Recipe with Spatio-Temporal Cue Gating for Streaming Video Understanding

👍 0

08/17 08:00

Streaming video understanding demands direct responses from the causally observed prefix of an unfolding video. Existing systems add inference-time memory, retrieval, and compression, yet a training-free sliding-window baseline already matches them. We therefore fix a memory-free recent-window proto

GRNEdit: Efficient General Video Editing from a New Binary-Evidence Perspective in Generative Refinement Networks

👍 13

08/17 08:00

Instruction-based general video editing seeks to unify diverse editing operations within a single, intuitive interface.

TRACE-Bench: Decomposing and Diagnosing Multi-Reference Image Generation

👍 9

08/17 08:00

Despite recent advances in unified multimodal models for multi-reference image generation, existing benchmarks remain organized around predefined task types (e.g., "subject composition"), which are ill-suited to this combinatorial setting and lead to fragmented coverage, uncontrolled complexity, and

Learn What's Left, Not What's Mastered: Saturation Aware Advantage Reweighting for Multi-Reward Policy Optimization

👍 44

08/17 08:00

Reinforcement learning (RL) with group-relative advantages has become the de facto standard for post-training language model reasoners. However, when optimizing multiple reward objectives, existing methods typically scalarize the reward vector with a fixed weighted sum before group-wise standardizat

AnyTalk: Speech Animation for Arbitrary Characters Leveraging a Video Generation Model

Measuring false alarms on human-verified-correct ProcessBench traces with the present task held byte-identical, w

HarnessEval-W: Agentifying the Evaluation of Visual Worlds

👍 110

08/17 08:00

A benchmark should deliver more than a scalar score: what makes an evaluation trustworthy is the reasoning that justifies the score. This is especially critical for world models, where judging a rollout requires understanding whether physics, causality, and world state evolve correctly. Humans spot

Improving the matrix multiplication exponent with modern optimization and AlphaEvolve

👍 10

08/17 08:00

The current best bounds on the matrix multiplication exponent ω are obtained through a refinement of the laser method called combination loss analysis (Duan et al., 2022; Williams et al., 2024; Alman et al., 2025). In this note, we address the optimization problem at the core of this approach and pr

Ventor-QTest: Threat-Model-Driven Verification of Vendor-Hosted LLM APIs

R^3-Bench: LLMs Struggle with Resource-Rational Reasoning under Shared Budgets

👍 11

08/17 08:00

In cognitive science, resource rationality asks how an agent should allocate limited computation to maximize expected value. Most reasoning and agent benchmarks use independent per-task budgets; existing shared-budget studies do not calibrate suite performance against the same model's demonstrated s

By generating intermediate reasoning images, Visual CoT provides an intuitive mechanism for visual foresight but introduces substantial inference overh

Large Discovery Models: Empirically-grounded Model-Based Open-Ended Search

👍 49

08/16 08:00

Scientific discovery often involves optimising expensive-to-evaluate objectives over vast, structured, and open-ended hypothesis spaces, such as molecules, protein sequences, and computer programs. Generative models such as large language models (LLMs) provide expressive priors over such spaces, but

UI-Mate: Advancing Open-Weight Foundation GUI Agents with In-Context Demonstrations

👍 33

08/16 08:00

Foundation GUI agents can automate complex digital tasks, but deployment is hindered by scarce and biased training data, ambiguous prompts, and unreliable execution. Routine workflows rely on user-specific tools and tacit conventions, so unstated instructions can produce arbitrary variations across

ConceptFormer: Learning Adaptive Latent Concepts for Query-Document Alignment in Visual Document Retrieval

StateM: Reaching 95.3% Raw Accuracy, or a \$15 Frontier Run, on Terminal-Bench 2.1 via Harness Scaling

👍 105

08/15 08:00

Long-horizon agents can fail even when their underlying models can solve the constituent steps. They may lose track of mutable state, fail to reactivate lessons from earlier executions, skip known procedures, or stop prematurely. We bet on harness scaling to improve the execution system around an ag

PACE-Bench: Benchmarking Physics Adaptation via Code Evolution in Dynamic Environments

👍 8

08/14 08:00

Self-evolving agents improve future behavior from interaction experience, yet existing evaluations typically optimize under fixed execution conditions and do not test recovery after those conditions change. To address this gap, we introduce PACE-Bench (Physics Adaptation via Code Evolution), a simul

Accuracy and Order Sensitivity Diverge Under Label-Free Strategies

👍 1

08/12 08:00

Multiple-choice benchmarks are widely used to evaluate large language models, but MCQ scores conflate knowledge with sensitivity to option order, which makes them unreliable measures of model knowledge. In this paper, we test whether preventing a model from seeing option labels while committing to a

Routine enterprise records, however, are work by-products in which required organizational relations remain implicit across heterogeneous sources. Existing benchmarks provide realistic multi-sou

When Context Bites: Detecting RAG Poisoning via Document-Level Attention Collapse

👍 1

08/07 08:00

Retrieval-augmented generation (RAG) is indispensable for enhancing large language models. However, RAGs are increasingly susceptible to poisoning attacks, in which adversarial documents are injected to manipulate generator outputs. Previous methods rely on output-side signals such as perplexity and

Position: AI Agents in Scientific Teams Should Be Studied as Human-Agent Systems

👍 1

08/02 08:00

Large language model-based agents are increasingly deployed as collaborators in scientific discovery yet most current work focuses on the autonomous capabilities of "AI Scientists". We argue that this overlooks the social aspects of scientific teamwork, and that studying AI Scientists as human-agent

Plausible but Not Valid: A Psychometric Audit of LLMs as Synthetic Survey Respondents

👍 2

07/06 08:00

Large language models (LLMs) are increasingly used as synthetic survey respondents, but existing evaluations ask whether answers look plausible at the individual level. We argue the right question is psychometric: do LLMs preserve the joint distribution, latent structure, reliability, mediation path

HarmProfile: Characterizing Harmful Distributions in Frontier LLMs

👍 1

06/11 08:00

Frontier large language models (LLMs) safety evaluation has largely treated harmful generation as an attack outcome rather than as an object of analysis.
