Proud that our work on multilingual bias evals made it into @wired.com! The paper is being presented today at #NAACL2025.

If you are at #ICLR25 and care about tokenizers, drop by Aleph Alpha’s Birds of a Feather session – happening now at Opal 103.

So while I believe our use for tweety (and even my RobBERT model trained in 2019) is well within the law, it is a worrying precedent set by Brein.

At the pressing request of Stichting BREIN, GEITje is no longer available as of today. All model files have been removed from my HuggingFace repositories1. GEITje was a Dutch-language large open langu...

.. instead of uni-backed Dutch LLMs like Fietje-2b by @bramvanroy.bsky.social (KUL) or our tweety-7b-dutch (KUL & UGent).

How copyright applies to LLMs is not so clearcut (it protects works from unauthorised distribution), since LLMs do not repeat training data unless severely oversampled.

I just found out that Stichting Brein took down GEITje, a Dutch 7B LLM made by Edwin Rijgersberg as a hobby project.

While its training corpus was indeed copyrighted (Gigacorpus), it is interesting that Brein went after a hobby project first.. 🧵 1/3

Not super multilingual, but for Dutch, German, French and English (all Belgian languages 🇧🇪) there is is this variant: huggingface.co/Parallia/Fai...

TweetyIta and ItaEval are a language model and evaluation benchmark for Italian tasks. What's more, they are 100% community-driven and born within RiTA (rita-nlp.org). @asantilli.bsky.social will present the poster on Dec 5, 16:30-17:30.

Unsure where to submit your next research paper to now that aideadlin.es is not updated anymore? And let’s be honest, is the location not as important as the conference itself?
