Financial question answering over SEC filings faces a subtle challenge: answers can be numerically correct yet grounded in wrong evidence, since similar facts recur across filing sections, time periods, and companies. FinRank introduces a benchmark of 1,185 expert-authored questions with gold evidence and curated hard negatives to specifically test provenance-sensitive retrieval. This is valuable for financial analysts, compliance teams, and fintech developers building QA systems over regulatory filings, where the paper's baseline results—showing even strong embedders struggle significantly with hard negatives—highlight the need for retrieval systems that verify evidence grounding, not just answer correctness, in high-stakes financial contexts.

Segmenting spacecraft in imagery typically requires manual annotation, but foundation segmentation models can generate pseudo-masks automatically, despite geometric inaccuracies that worsen during distillation. GeoDistill-Refine improves this by stabilizing teacher predictions through prompt fusion and refining a lightweight student network using silhouette, boundary, and shape-based objectives, filtered by a reliability gate. This is directly applicable to space situational awareness, satellite servicing, and space debris tracking, where accurate, annotation-free spacecraft segmentation is valuable. The resulting compact model runs efficiently (1.1ms per image) while improving boundary and region accuracy across multiple spacecraft imagery domains.

LLMs have typically been evaluated on geo-related tasks in narrow, homogeneous settings, obscuring how well they generalize across diverse geospatial and temporal challenges. GeoBenchLLM addresses this by combining twelve public datasets into a comprehensive benchmark covering varied geo-related tasks and domains. This is useful for researchers and developers building geospatial AI applications—such as mapping tools, location-based services, climate or urban analytics, and geographic question-answering systems—needing to understand which model characteristics (the paper highlights reasoning ability and model size) most influence performance, guiding model selection for real-world geospatial deployment.

Real-world video understanding often requires identifying and tracking specific individuals across multimodal content, a capability underserved by existing video-text benchmarks. This paper introduces the Identity-conditioned Queries task and the ISYV framework, including a challenging benchmark, large training dataset, and model designed to jointly reason over a reference image and video content for identity grounding and behavior understanding. Applications include surveillance analytics, video search and retrieval, media content indexing, and any system needing to track or answer questions about specific people across long videos—an area where current mainstream models notably struggle, especially with cross-domain matching.

Training AI agents for complex, multi-turn clinical reasoning—like a medical resident gaining experience—remains underdeveloped despite LLMs' strong performance on static medical exam benchmarks. ResidencyRL trains clinical AI agents through simulated adversarial patient encounters spanning many dialogue turns and tool calls, rewarding diagnostic accuracy, safety, and communication quality. This has clear applications in clinical decision support, medical training simulators, and diagnostic assistant tools, showing improved diagnostic accuracy and reduced missed red flags versus baseline models, with expert clinicians preferring the trained agent's performance—though real-world prospective validation remains necessary before clinical deployment.

Test-time scaling strategies for LLM reasoning—generating more samples, longer chains of thought, or stronger verification—compete for a fixed compute budget, raising the question of where to best allocate resources. CoBa formulates this as a routing problem, first applying cheap verification broadly before directing only uncertain or high-value candidates to stronger, costlier verification. This benefits applications requiring efficient, high-accuracy reasoning under budget constraints, such as automated math and reasoning solvers, where CoBa matched or approached best-of-N sampling performance while using roughly half the compute, offering a practical framework for cost-effective test-time reasoning system design.

LLM inference dominates AI's operational energy use, and numerical time-series data—like telecom network metrics—creates especially inefficient token-heavy inputs when represented as text. This paper shows that converting time-series data into 2D visual plots and processing them with vision-language models dramatically reduces token counts and energy consumption while improving accuracy. Applications include telecom network monitoring, anomaly detection in 4G/5G infrastructure, and broader numerical time-series analysis tasks constrained by context window limits. This approach offers a practical path toward more sustainable, accurate AI systems for industries handling large volumes of sensor or KPI data.

Language agents with long-term memory face a "memory pollution" problem: outdated facts remain retrievable even after the real-world situation changes, corrupting downstream reasoning. TEPA addresses this by treating memory validity as an explicit, revocable state, automatically invalidating stale precedents when contradicting evidence appears while preserving history for audit purposes. This is applicable to any long-running AI agent system needing to track evolving facts, preferences, or environment states reliably—such as personal assistants, enterprise knowledge agents, or monitoring systems—where TEPA substantially outperformed append-only and last-write-wins memory approaches during simulated real-world drift and reversal scenarios.

Diffusion-based LLMs use a fundamentally different generation process than standard autoregressive models, and their safety mechanisms are poorly understood. This paper reveals that safety alignment in diffusion LLMs is sparse and often inherited from autoregressive source models, making them vulnerable to transfer-based jailbreak attacks. The authors introduce SN-Guided Diffusion, an offline black-box jailbreak achieving high success rates across multiple model families. This research is critical for AI safety and red-teaming teams working on diffusion LLM deployment, highlighting urgent vulnerabilities that need addressing before these models see wider adoption, given attack transferability to major proprietary systems.

Vision-language models (VLMs) are advancing rapidly, but building benchmarks that meaningfully stress-test their weaknesses is costly and labor-intensive. SABRE offers an automated pipeline converting task specifications into structured images and question-answer pairs, using automated filtering plus human review to ensure benchmark quality and difficulty. Its SABRE-Prior instantiation specifically tests whether VLMs rely on genuine visual evidence versus learned world priors. This is useful for AI evaluation teams and VLM developers needing scalable, refreshable stress tests, revealing that current VLMs struggle significantly (17.8%-31.3% accuracy) with counterfactual scenes, textures, and misleading language cues.
