The Best Programming Language for Tokenmaxxing: An Investigation of Coding Agent Behavior Across Programming Languages

Zixuan Wu, Carolyn Jane Anderson, Arjun Guha

Although coding agents are now very effective in a variety of programming languages, this paper first shows that the cost (in tokens) can very significantly by programming language…

AgentPack: A Dataset of Code Changes, Co-Authored by Agents and Humans

Yangtian Zi, Zixuan Wu, Aleksander Boruch-Gruszecki +2

Fine-tuning large language models for code editing has typically relied on mining commits and pull requests. The working hypothesis has been that commit messages describe human int…

Agnostics: Learning to Code in Any Programming Language via Reinforcement with a Universal Learning Environment

Aleksander Boruch-Gruszecki, Yangtian Zi, Zixuan Wu +4

Large language models (LLMs) already excel at writing code in high-resource languages such as Python and JavaScript, yet stumble on low-resource languages that remain essential to…

Mastering the Minority: An Uncertainty-guided Multi-Expert Framework for Challenging-tailed Sequence Learning

Ye Wang, Zixuan Wu, Lifeng Shen +4

Imbalanced data distribution remains a critical challenge in sequential learning, leading models to easily recognize frequent categories while failing to detect minority classes ad…

ReasoningWeekly: A General Knowledge and Verbal Reasoning Challenge for Large Language Models

Zixuan Wu, Francesca Lucchetti, Aleksander Boruch-Gruszecki +5

Existing benchmarks for frontier models often test specialized, "PhD-level" knowledge that is difficult for non-experts to grasp. In contrast, we present a benchmark with 613 probl…

GlyphPattern: An Abstract Pattern Recognition Benchmark for Vision-Language Models

Zixuan Wu, Yoolim Kim, Carolyn Jane Anderson

Vision-Language Models (VLMs) building upon the foundation of powerful large language models have made rapid progress in reasoning across visual and textual data. While VLMs perfor…
