OpenEuroLLM

A series of foundation models for transparent AI in Europe

[OpenEuroLLM @OpenEuroLLM]

HPLT is of the datasets we are sharing in our world-readable catalogue across HPCs. Interesting talk!

[HPLT @hplt_eu]

We are at #LREC2026 presenting HPLT v3 Datasets, monolingual, parallel, massive, highly curated. For depth info and analysis, please:

Join us in room Menorca 1 at 16:20!!!

[OpenEuroLLM @OpenEuroLLM]

All ready to share information about #OpenEuroLLM with the #LREC2026 crowd. Let's talk data, infra, evals and open multilingual LLM models together! Come to booth #5 at the poster area 1, Elyxir Building.

Also, today, know more about bechmark contamination impact goint to the poster of our colleagues from the unversities of Helsinki and Turku and the ELLIS Institute Finland.

[OpenEuroLLM @OpenEuroLLM]

Quite a nice "representation" of the OpenEuroLLM crowd will be at the International Conference on Learning Representations (ICLR) this week.
On Friday 24, come to poster "OpenThoughts: Data Recipes for Reasoning Models", work partially supported by our project, and meet us!👋

Experimenting with model-based annotation for better data selection? A candidate to consider is propella-1, a multi-property annotator partially funded by #OpenEuroLLM which is fully open-source.

🔓Code, annotations and paper available! https://t.co/oemVhuO8pR

[ellamind @ellamindAI]

We released propella-1, a small model for advanced pre-training data annotation 🙃.

Work led by @maxidahl within the @OpenEuroLLM project. Link to model + annotations for important pre-training datasets below 👇

🎉 One year of OpenEuroLLM!

🇪🇺We’re building Europe’s next-gen open-source LLMs to boost digital sovereignty.

Strategic access to EuroHPC resources granted to OpenEuroLLM!!!

-first AI project granted strategic access across multiple EuroHPC centres
-for over 10 million GPU hours

Thanks @EUComission and @EuroHPC_JU!

[Jan Hajic @HajicJan]

Proud to present the @OpenEuroLLM project and its results so far, with Sampo Pyysalo (@UniTurku) at the 1st Workshop on Open Source Sovereign LLMs in Berlin https://t.co/gMalOuRGm3 Great opportunity to talk to many OS LLM developers! @CharlesUniPRG @hplt_eu

[OpenEuroLLM @OpenEuroLLM]

We strongly agree! Let's make it happen! Thanks @EU_Budget & STEP for the support.

[EU Budget @EU_Budget]

Future-proof AI in all EU languages isn’t a dream, it’s OpenEuroLLM 🗣️💬

9 countries, the EU budget & STEP join forces to build transparent, AI Act-compliant tech for Europe’s innovators.

[OpenEuroLLM @OpenEuroLLM]

Well done #HPLT, we surely need more high performance datasets for the present and future landscape of multilingual LLMs. See you at #emnlp2025!

[HPLT @hplt_eu]

The #HPLT crowd is at #EMNLP2025!!!

If you are around, please visit our booth to discuss:

- multilingual datasets 🌏
- dataset insights and stats 📊
- dataset performance 🔝
- efficient MT models ⏱️
- and the future of multilingual LLMs 💡

We don't want to miss U!

[OpenEuroLLM @OpenEuroLLM]

OpenEuroLLM completing 2 days of sharing progress and next steps pursuing the goal of developing strong multilingual foundation models aligned with European strategic vision & standards.

Gathering at BSC nearby MareNostrum 5 supercomputer made us feel home.

LeoLM has since been an inspiration for many other projects (like our DiscoLM 8b, the @occiglot models, and more) and serves as a conceptual baseline for some ideas within the @OpenEuroLLM project to bring strong LLMs to all European languages.

[ellamind @ellamindAI]

Our co-founders project #LeoLM highlighted by @bmftr_bund.
Today, we´re continuing what started as a student`s side-project with @OpenEuroLLM (and more to come).
If you want to work on Open Source AI, multilingual applications and AI evaluations as well - we´re hiring! 🙂

[Jenia Jitsev 🏳️‍🌈 🇺🇦 🇮🇱 🇮🇷 @JJitsev]

This was first, but surely not the last colab between open-sci, @laion_ai and @openEuroLLM. Establishing baselines and good starting grounds for experiments to create strong open foundation models is important, and I am happy to see it worked out so well.

[OpenEuroLLM @OpenEuroLLM]

📢 First release: 38 monolingual reference LLMs (2.15B params) via @hplt_eu + #OpenEuroLLM

⚙️Trained on 100B tokens from HPLT v2 dataset
🌍 Cover EU langs + others
⚙️ Based on LLaMA, trained on #LUMI
📈 Useful for evaluation

It's time for transparent AI in Europe. It's time for open LLMs as a robust foundation for developing future private and public AI services. It's time for:

OPEN = open-source
Euro = under EU regulations, representing EU values
LLM = LLMs
