I completed my postdoc at Princeton University 9 months ago but never wrote a goodbye post so:
My two years at Princeton were the best 2 years of my life. I'm forever grateful to @karthik_r_n, @prfsanjeevarora & Ellen DiPippo for creating the incredible environment that enabled me to be take part in amazing research.
I'm forever grateful to @closji & @jyangballin for meeting me on my fourth day on the job and then inviting me to join the software engineering benchmark they had developed. And to @KLieret who joined us just after and became a core part of the SWE-team.
Thank you @ShunyuYao12 who met with me when I was making the decision; I enjoyed our walks so much I decided to join just so I could go on more walks with Shunyu.
Thank you @_awettig my collaborator in both science and art, and European<->American linker.
Thank you to my FAIR postdoc hosts @syhw and @sidawxyz.
Thank you to *all* of my collaborators, including first authors: @MinyangTian1 SciCode and CritPt, @AbramovichTalor SWE-agent for Cyber Security, @OriYoran AssistantBench, @18jeffreyma SWE-fficiency, @a1zhang VideoGameBench, @MiniHui_zhu CritPt, and @ori_press my actual brother and author of AlgoTune
Thank you to my senior collaborators: @Diyi_Yang & @lschmidt3 (through John), @haopeng_uiuc (through Minyang), @profvjreddi (through Jeff), @JonathanBerant (through Ori Yoran) and @MatthiasBethge (through Ori Press).
Thank you to all the people at Princeton who made PLI what it is: @danqi_chen @cocosci_lab and all of the other faculty, postdocs, graduate and undergraduate students.

How do LLMs think about thinking? 🤔
In the latest Kempner Seminar Series talk, @prfsanjeevarora (@PrincetonPLI, @PrincetonCS) explores how “metacognition” shapes problem-solving in large language models.

Claude Skills shows performance benefits from leveraging LLM skill catalogs at inference time. Our previous work (linked under thread 5/5) showed the same 6 months ago! 🌟Our new work, STAT, shows that leveraging skills during training can greatly help too‼️, e.g., Qwen can continue to learn new tricks from Hendrycks MATH, which it had been over-trained on.
🚨 We introduce Skill-Targeted Adaptive Training (STAT), which uses a supervisor model and a skill catalog to construct a 🧩Missing-Skill-Profile for each student model, and then modifies training to squeeze out >=7% more performance! The intervention can be as simple as reweighting existing training sets. You can also think of this as a more effective distillation method. More in threads 🧵

EVERYONE PREFERS HUMAN WRITERS, INCLUDING AI We know humans are biased against AI-creativity but what about LLMs, now often judging creativity in various contexts? Check out new preprint from PLI Seed Grant Recipients, Meridith Martin and Wouter Haverals arxiv.org/pdf/2510.08831

Is online alignment the only path to go despite being slow and computationally expensive?
Inspired by prospect theory, we provide a human-centric explanation for why online alignment (e.g. GRPO) outperforms offline alignment (e.g. DPO, KTO) and empirically show how to close the online-offline gap with Humanline, a simple yet consistently effective two-part design.
💡Main finding: Applying humanline on top of offline objectives can perform on par with their online counterparts on both instruction following and mathematical reasoning. Consistent gains across different objectives, model families and model sizes!
