Agent Safety From Within: Detecting Harmful Trajectories from LLM Internal States

Difan Jiao, Ashton Anderson

Language model agents can now perform sophisticated sequences of actions via tools and harnesses, which has increased the scope of the damage they can cause. Guard models, however,…

Tandem Reinforcement Learning with Verifiable Rewards

Difan Jiao, Raghav Singhal, Robert West +1

Reinforcement learning with verifiable rewards (RLVR) has driven substantial gains in language-model reasoning. However, models fine-tuned with RLVR need not remain compatible with…

Chessformer: A Unified Architecture for Chess Modeling

Daniel Monroe, George Eilender, Philip Chalmers +2

Chess has long served as a canonical testbed for artificial intelligence, but modeling approaches for its central tasks have diverged. Maximizing playing strength, predicting human…

LLM Safety From Within: Detecting Harmful Content with Internal Representations

Difan Jiao, Yilun Liu, Ye Yuan +4

Guard models are widely used to detect harmful content in user prompts and LLM responses. However, state-of-the-art guard models rely solely on terminal-layer representations and o…

ThinkTwice: Jointly Optimizing Large Language Models for Reasoning and Self-Refinement

Difan Jiao, Qianfeng Wen, Blair Yang +2

We introduce ThinkTwice, a simple two-phase framework that jointly optimizes LLMs to solve reasoning problems and refine the answers, based on Group Relative Policy Optimization (G…

Grounded Chess Reasoning in Language Models via Master Distillation

Zhenwei Tang, Qianfeng Wen, Seth Grief-Albert +4

Language models often lack grounded reasoning capabilities in specialized domains where training data is scarce but bespoke systems excel. We introduce a general framework for dist…

Level Up: Defining and Exploiting Transitional Problems for Curriculum Learning

Amogh Inamdar, Zhenwei Tang, Ashton Anderson +1

Curriculum learning--ordering training examples in a sequence to aid machine learning--takes inspiration from human learning, but has not gained widespread acceptance. Static strat…

When AI Gives Advice: Evaluating AI and Human Responses to Online Advice-Seeking for Well-Being

Harsh Kumar, Jasmine Chahal, Yinuo Zhao +4

Seeking advice is a core human behavior that the internet has reinvented twice: first through forums and Q&A communities that crowdsource public guidance, and now through large lan…

ChessQA: Evaluating Large Language Models for Chess Understanding

Qianfeng Wen, Zhenwei Tang, Ashton Anderson

Chess provides an ideal testbed for evaluating the reasoning, modeling, and abstraction capabilities of large language models (LLMs), as it has well-defined structure and objective…

SEAM: Semantically Equivalent Across Modalities Benchmark for Vision-Language Models

Zhenwei Tang, Difan Jiao, Blair Yang +1

Evaluating whether vision-language models (VLMs) reason consistently across representations is challenging because modality comparisons are typically confounded by task differences…

Learning to Imitate with Less: Efficient Individual Behavior Modeling in Chess

Zhenwei Tang, Difan Jiao, Eric Xue +4

As humans seek to collaborate with, learn from, and better understand artificial intelligence systems, developing AIs that can accurately emulate individual decision-making becomes…

ChatBench: From Static Benchmarks to Human-AI Evaluation

Serina Chang, Ashton Anderson, Jake M. Hofman

With the rapid adoption of LLM-based chatbots, there is a pressing need to evaluate what humans and LLMs can achieve together. However, standard benchmarks, such as MMLU, measure L…

Maia-2: A Unified Model for Human-AI Alignment in Chess

Zhenwei Tang, Difan Jiao, Reid McIlroy-Young +3

There are an increasing number of domains in which artificial intelligence (AI) systems both surpass human ability and accurately model human behavior. This introduces the possibil…
