Hybrid Reasoning Agents

Jiaru Zou, Yunzhe Qi, Sirui Chen +5

How can we build an agent that thinks beyond human language, yet still acts through it in the external environment? Modern LLM agents still reason and interact through text, while…

Harnessing the Collective Intelligence of AI Agents in the Wild for New Discoveries

Federico Bianchi, Yongchan Kwon, Aneesh Pappu +1

Scientific discovery is often a collective process: researchers share partial results, inspect failed attempts, and build on each other's ideas over long time horizons. Recent AI s…

Automated Benchmark Auditing for AI Agents and Large Language Models

Junlin Wang, Federico Bianchi, Shang Zhu +4

Modern AI benchmarks operate at a complexity that outpaces traditional verification methods. Tasks authored by domain experts often contain implicit assumptions, incomplete environ…

Evaluating Commercial AI Chatbots as News Intermediaries

Mirac Suzgun, Emily Shen, Federico Bianchi +5

AI chatbots are rapidly shaping how people encounter the news, yet no prior study has systematically measured how accurately these systems, with their proprietary search integratio…

"Sorry, I Didn't Catch That": How Speech Models Miss What Matters Most

Kaitlyn Zhou, Martijn Bartelds, Federico Bianchi +1

Despite speech recognition systems achieving low word error rates on standard benchmarks, they often fail on short, high-stakes utterances in real-world deployments. Here, we study…

Learning to Discover at Test Time

Mert Yuksekgonul, Daniel Koceja, Xinhao Li +8

How can we use AI to discover a new state of the art for a scientific problem? Prior work in test-time scaling, such as AlphaEvolve, performs search by prompting a frozen LLM. We p…

Test-Time Optimization of Physical Query Plans with LLMs

Mehmet Hamza Erol, Xiangpeng Hao, Federico Bianchi +3

Traditional query optimization relies on cost-based optimizers that estimate execution cost (e.g., runtime, memory, and I/O) using predefined heuristics and statistical models. Imp…

DSGym: A Holistic Framework for Evaluating and Training Data Science Agents

Fan Nie, Junlin Wang, Harper Hua +6

Data science agents promise to accelerate discovery and insight-generation by turning data into executable analyses and findings. Yet existing data science benchmarks fall short du…
