The project that started my whitespace obsession... #EMNLP2025 While we've all been worrying about tokenizers, lurking in the background has been the preprocessing *before* tokenization. Poems break standard HTML-to-text linearization systems, and we find that multimodal models aren't a solution.

Whitespace is a critical component of poetic form, reflecting both adherence to standardized forms and rebellion against those forms. Each poem's whitespace distribution reflects the artistic choices ...

Go check Alex's poster today (Wed) in Suzhou! #EMNLP2025 I'm still so proud of our work (led by @lasha.bsky.social) on CondaQA, so we had to ask what would happen if we tried to create high-quality reasoning-over-text benchmarks now that LLMs are available. Turns out, we'd make an easier benchmark!

AI always calling your ideas “fantastic” can feel inauthentic, but what are sycophancy’s deeper harms? We find that in the common use case of seeking AI advice on interpersonal situations—specifically conflicts—sycophancy makes people feel more right & less willing to apologize.

LLMs are trained to mimic a “true” distribution—their reducing cross-entropy then confirms they get closer to this target while training. Do similar models approach this target distribution in similar ways, though? 🤔 Not really! Our new paper studies this, finding 4-convergence phases in training 🧵

💡Beyond math/code, instruction following with verifiable constraints is suitable to be learned with RLVR. But the set of constraints and verifier functions is limited and most models overfit on IFEval. We introduce IFBench to measure model generalization to unseen constraints.
