🚀Let’s Think Only with Images. No language and No verbal thought.🤔 Let’s think through a sequence of images💭, like how humans picture steps in their minds🎨. We propose Visual Planning, a novel reasoning paradigm that enables models to reason purely through images.

We achieved the first instance of successful subword-to-byte distillation in our (just updated) paper. This enables creating byte-level models at a fraction of the cost of what was needed previously. As a proof-of-concept, we created byte-level Gemma2 and Llama3 models. 🧵

🔥 We teach LLMs to say how confident they are on-the-fly during long-form generation. 🤩No sampling. No slow post-hoc methods. Not limited to short-form QA! ‼️Just output confidence in a single decoding pass. ✅Better calibration! 🚀 20× faster runtime. arXiv:2505.23912 👇

Our LTL team had an amazing time at M2L school in Croatia 🇭🇷! 🏆 Hannah won Best Poster Award! → arxiv.org/html/2509.1481… 🎤 Ivan Vulić delivered an amazing lecture → drive.google.com/file/d/1feqnLe…

Instruction tuning unlocks incredible skills in LLMs, but at a cost: they become dangerously overconfident. You face a choice: a well-calibrated base model or a capable but unreliable instruct model. What if you didn't have to choose? What if you could navigate the trade-off?

AI that is “forced to be good” v “genuinely good” Should we care about the difference? (yes!) We’re releasing the first open implementation of character training. We shape the persona of AI assistants in a more robust way than alternatives like prompting or activation steering.
