The next generation of open LLMs should be inclusive, compliant, and multilingual by design. That’s why we @icepfl.bsky.social @ethz.ch @cscsch.bsky.social ) built Apertus.
EPFL, ETH Zurich & CSCS just released Apertus, Switzerland’s first fully open-source large language model.
Trained on 15T tokens in 1,000+ languages, it’s built for transparency, responsibility & the public good.

🚀 Big time! We can finally do simple LLM RL fine-tuning with rewards and leverage offline/off-policy data!
❌ You want rewards, but GRPO only works online?
❌ You want offline, but DPO is limited to preferences?
✅ QRPO can do both!
🧵Here's how we do it:

⚡️🧠 Excited to share our recent work on long-context efficiency! We propose a new layer called RAT—fast and lightweight like RNNs, yet powerful like Attention. 🐭✨ This is the joint effort with Anunay Yadav, @razvan-pascanu.bsky.social @caglarai.bsky.social !

A dream come true! I presented "No Representation, No Trust" on my favorite RL podcast, TalkRL!
Make sure to check it out to learn why training with PPO for too long makes your agent collapse!

Excited to share that the first paper of my PhD has been accepted for publication at the ISPRS Geospatial Week 2025! This dataset paper introduces a globally representative, high-resolution (10m) benchmark dataset for Above Ground Biomass estimation.
