@VikParuchuri @vanstriendaniel @huggingface This is actually pretty good. Can the layout be done separately, extract the bounding boxes for reading order, and run again on them?

[Javier de la Rosa @[email protected] @versae]

@vanstriendaniel @huggingface Nice! We are currently testing these models out too. Any chance you can add Chandra as well? It's the one that worked best for our newspaper collection so far.

[Javier de la Rosa @[email protected] @versae]

@vanstriendaniel Nice! Norwegian Bokmål is also here 🇳🇴

@lirondos @sistema_arText @JulioGonzalo1 @ConstantineLig @UNEDNLP ¡Enhorabuena! Un trabajo excepcional, sin duda.

@giffmana We tried something like that, but obviously limiting A LOT the ablations. Impossible to cover it all.

@michahu8 Will do! Last question, any experiments on tokenizer impact?

[Javier de la Rosa @[email protected] @versae]

@michahu8 Awesome! I didn't get to the appendices yet 😅 Thanks for pointing that out. I'll be testing it on languages other than English, including extremely low-resource.

🚀 We're Hiring Applied AI Engineers! 🚀

Do you write clean, efficient Python? Are you familiar with AI frameworks? Do you thrive in a collaborative team?

If that sounds like you, DM me now! Let's build the future of AI together. 💡🤖

[Javier de la Rosa @[email protected] @versae]

@maballesterosv En general, sí. Pero depende de la abilidad concreta que se le espera un LLM hoy en día. La mayoría de los modelos son entrenamientos base (pre-training), sin capacidad para seguir instrucciones o los diálogos (post-training).

[Javier de la Rosa @[email protected] @versae]

Our work on copyright and LLMs is finally out 😎 I know it's not DeepSeek or Qwen, but I still think is very interesting stuff!

[Javier de la Rosa @[email protected] @versae]

📢✨ PAPER ALERT ✨📢
Ever wondered whether copyrighted material **actually** makes for better LLMs? 🤔 We asked the same question—and the results are in! Our paper is accepted at NoDaLiDa/Baltic-HLT 2025, and the pre-print is live: 🔗 https://t.co/RJFZMouSD5 🧵👇
