Evaluate your policy on REALM - our new real-to-sim validated benchmark for generalization in robot manipulation!

REALM is a good real-world proxy, evidenced by the high correlation with real-world evals.

ALSO: Follow the rising star @msedlacek.bsky.social and ask him any questions about REALM!

🚀 new state-of-the-art on ILIAS dataset!

Curious how well the latest models can recognize particular objects?
We evaluated the base and large variants of DINOv3 and Perception Encoder (PE) on instance-level image retrieval.

Our remote sensing foundation model Galileo has been accepted to ICML 2025!

Galileo outperforms state-of-the-art across different input data modalities and shapes, and using it requires only minimal data and compute.

Can you train a performant language model using only openly licensed text?

We are thrilled to announce the Common Pile v0.1, an 8TB dataset of openly licensed and public domain text. We train 7B models for 1T and 2T tokens and match the performance similar models like LLaMA 1 & 2

#KostasThoughts: As an AC, it’s frustrating when reviewers only see the rebuttal through the lens of their own review. Step back—consider all reviews and discussions. DON’T rush to finalize; see the FULL picture!

#KostasThoughts: There is no shame getting the initial review wrong, e.g., by missing an important detail. It is wrong when you let your ego get in the way of arriving at the correct decision.
