Are we experiencing a 'GPT moment' in vision?
In our new preprint, we show that generative video models can solve a wide range of tasks across the entire vision stack without being explicitly trained for it.

🎉 Excited to present our paper VGGSounder: Audio‑Visual Evaluations for Foundation Models today at #ICCV2025!
🕦 Poster Session 1 | 11:30–13:30
📍 Poster #88
Come by if you're into audio-visual learning and want to know whether multiple modalities actually help or hurt.

New preprint out! 🎉
How does LLM training loss translate to downstream performance?
We show that pretraining data and tokenizer shape loss-to-loss scaling, while architecture and other factors play a surprisingly minor role!

CuratedThoughts: Data Curation for RL Datasets 🚀
Since DeepSeek-R1 introduced reasoning-based RL, datasets like Open-R1 & OpenThoughts emerged for fine-tuning & GRPO. Our deep dive found major flaws — 25% of OpenThoughts needed elimination by data curation.
Here's why 👇🧵
