I'm forcing GPT-5.1 to translate some English text to some target language that I don't know. It decides to use its thinking feature, and then reasons about switching to the target language for the entire output, including explanations and conversational parts. Sigh.

This week at #EMNLP2025, I'll present our research on pretraining a multilingual pixel language model. Join the multilinguality session on Friday at 10:30 in Room A301 to learn more about pixel models and their benefits in multilingual settings. (Unfortunately I’ll be on Zoom)

When is a language hard to model? Previous research has suggested that morphological complexity both does and does not play a role, but it does so by relating the performance of language models to corpus statistics of words or subword tokens in isolation.

📢New preprint: We introduce 📏Cetvel, a unified benchmark for evaluating language understanding, generation, and cultural capacity of LLMs in Turkish🇹🇷 #AI #LLM #NLProc

Joint work with Abrek Er, @gozdegulsahin.bsky.social, @aykuterdem.bsky.social from KUIS AI Center.

Excited to share that our paper "Multilingual Pretraining for Pixel Language Models" has been accepted to the #EMNLP2025 main conference! Please see the thread below and the paper itself for more details.

Announcing our recent work “Multilingual Pretraining for Pixel Language Models”! We introduce PIXEL-M4, a pixel language model pretrained on four visually & linguistically diverse scripts: English, Hindi, Ukrainian & Simplified Chinese. #NLProc
