229<p>Hi! I’m Yuyang Song, a first-year PhD student in Computer Science at <

229a href="https://www.cs.utexas.edu/">University of Texas at Austin</a>, where I feel fortunate to be advised by Prof. <a href="https://yizhongw.github.io/">Yizhong Wang</a>. I earned my B.S. in Computer Science at the Wu Yuzhang Honors College, <a href="http://en.scu.edu.cn/">Sichuan University</a>, under the supervision of Prof. <a href="https://merlintang.github.io/">Mingjie Tang</a>. From October 2025 to July 2026, I was a member of the Foundation Model Group at IQuest AI Lab, Ubiquant.</p>
230
231<p>I’m broadly interested in <strong>how data shapes a model as it flows through training, and how architecture and training should be designed around that flow</strong>, with efficiency as a guiding principle. Rather than treating the model, its data, and its training as separate problems, I see them as forces that continually shape one another, and I want to understand how to harness that interplay to build capable models more efficiently.</p>

241IQuest-Q1 is an open-source agentic foundation model for CLI systems. A sparse Mixture-of-Experts model with 320B total parameters and 15B activated, it combines general and coding agent capabilities with efficient compute for medium- and long-horizon tasks. During development, it also takes part in its own improvement under human supervision.</p>

254We study how large-scale, execution-grounded terminal trajectories reshape the agentic capabilities of code LLMs. Trained on this data, TerminalTraj-32B achieves state-of-the-art results among models under 100B parameters and matches models more than 10× larger, while showing markedly steeper test-time scaling—evidence that the right training data, not just scale, drives terminal agent capability.</p>

266IQuest-Coder-V1 is a new family of code large language models (LLMs) designed to advance autonomous software engineering and code intelligence. Built on the innovative code-flow multi-stage training paradigm, IQuest-Coder-V1 captures the dynamic evolution of software logic, delivering state-of-the-art performance across critical dimensions.</p>
