🌟NEW PAPER🌟 Do you know that changing a visual marker from red to blue can completely reorder VLM leaderboards? In our most recent work, we explore the fragility of visually prompted benchmarks. lisadunlap.github.io/vpbench…

🤔 SAGE started out of curiosity as to why agentic post training had not made a big impact for developing video models in mid 2025. 💡With entertainment videos as our testbed, we find that one can turn great "direct" models into awesome "any-horizon agents" with effortful RL!

🎥 Introducing SAGE, an agentic system for long video reasoning on entertainment videos—sports, vlogs, & more. It learns when to skim, zoom in, & answer questions directly. On our SAGE-Bench eval, SAGE with a Molmo 2 (8B)-based orchestrator lifts accuracy from 61.8% → 66.1%. 🧵

Some properties of LLMs only emerge with scale, one of which is the ability to effectively generalize from diverse data. During my internship @physical_int, we uncovered an emergent property of VLAs: as we scale up pre-training, VLAs can naturally learn from human video data!

We discovered an emergent property of VLAs like π0/π0.5/π0.6: as we scale up pre-training, the model learns to align human videos and robot data! This gives us a simple way to leverage human videos. Once π0.5 knows how to control robots, it can naturally learn from human video.

🎥 Introducing Split-then-Merge: A new video composition framework! This approach enables the composition of any foreground video with any background video. Unlike conventional methods that rely on annotated datasets or handcrafted rules, Split-then-Merge (StM) splits a large unlabeled corpus of videos into dynamic foreground and background layers, then merges them to learn how dynamic subjects interact with diverse scenes. Work done in collaboration with team members at @Google: Du Tran (@dutran) , Yujia Chen (@IssacCyj) , Prof. Ming-Hsuan Yang (@MingHsuanYang), Vincent Chu: and my advisor at UIUC (@siebelschool): Prof. James M. Rehg (@RehgJim). I will be attending NeurIPS, San Diego and would be happy to chat more! 🔗Project Webpage: split-then-merge.github.io/ 📄Paper: arxiv.org/abs/2511.20809

Can we scale up mobile manipulation with egocentric human data? Meet EMMA: Egocentric Mobile MAnipulation EMMA learns from human mobile manipulation static robot data — no mobile teleop needed! EMMA generalizes to new scenes and scales strongly with added human data. 1/9

Robots struggle to learn new skills from human videos. Why? We found that naive co-training produces disjoint distributions. Our EgoBridge (NeurIPS’25) extends Optimal Transport to align human-robot latents, improving success by 44% and generalization to human-only tasks!🧵

Are AI scientists already better than human researchers? We recruited 43 PhD students to spend 3 months executing research ideas proposed by an LLM agent vs human experts. Main finding: LLM ideas result in worse projects than human ideas.
