Can diffusion learn physical dynamics directly in 3D space? Yes!
Introducing 🫧PhysiFormer🫧 — a unified model that generates physically plausible multi-object, multi-material 4D dynamics in world space, conditioned on initial per-vertex positions and velocities.

Thrilled to learn from so many amazing insights!
"Visual General Intelligence: A White Paper"
is now on arXiv! arxiv.org/abs/2608.25924
We've discussed:
- What is Visual Intelligence?
- Can we develop it toward General Intelligence (VGI)?
In the VGI white paper, we bring together diverse perspectives on Visual Intelligence and discuss how intelligence grounded in visual modalities and experiences could develop toward General Intelligence.
Beyond proposing a single definition of VGI, we introduce, propose, and discuss different perspectives on what Visual Intelligence could be and how we could develop it toward General Intelligence.
This paper is a starting point for a broader discussion on the future of Visual Intelligence.
Many thanks to all the great co-authors!

Excited to share that our paper introducing BAS (Behavioral Alignment Score), a decision-theoretic metric for evaluating LLM confidence, was accepted to COLM 2026! 🎉

🎁 We are pleased to introduce Syn4D, a large-scale multiview synthetic dataset for dynamic scenes, accepted at #ECCV2026.
The complete dataset, including its dense geometric annotations, is now publicly available.

Amazing work. Always so in awe of @ayushnoori! Cannot overstate the importance of systematic logging for medical AI. Accurate, consistent, and complete data is key to safe and reliable AI-assisted healthcare.
How can we log, audit, and improve deployed AI models and agents for medicine? 🏥
AI is rapidly entering the clinic. Although models are already deployed across millions of patients, there is no consistent approach to monitor model use, assess performance, detect failure modes, or measure clinical impact. Model cards and data sheets describe a model before deployment. After deployment, there is no standard to record how, when, by whom, and for whom health AI models are used.
We need a “black box” flight recorder for medical AI. ✈️
Co-supervised by @zakkohane and @marinkazitnik, I led a team across 53 institutions and 11 countries to develop MedLog, a protocol for event-level logging of medical AI. Each time an AI model makes a prediction, MedLog creates a record with nine core fields: header, model, user, target, inputs, artifacts, outputs, outcomes, and feedback.
In our updated pre-print, we now report four real-world pilot implementations of MedLog across the US, Switzerland, and Vietnam. Predictive and generative AI, with 3M+ logged model invocations across up to 791K patients.
🇨🇭ICU deterioration monitoring in Switzerland: 223,840 records, 114 days, 212 patients
🇻🇳Wearable tetanus progression monitoring in Vietnam: 3,406 records, 289 days, 15 patients
🇺🇸LLM-based sepsis quality reporting in San Diego: 3,766 records, 89 days, 60 patients
🇺🇸Patient non-attendance prediction in New York: 2,914,264 records, 244 days, 791,319 patients

So incredibly proud of @aneeshers’s work on real time RL!! Featuring a lightweight gating policy that picks how long to plan, no time wasted. 🚀
Replying to @yimiche @Oxford_VGG
🍎 Project page visualisations highlight PhysiFormer’s physical understanding, including mass-invariant free fall and momentum transfer during collisions.

Many thanks to my amazing labmates @gboduljak, @Koichi_N_, @CodyJzr, @StanSzymanowicz, @MinghaoChen23 for insightful discussions!
Special thanks to @rhodes_trust for the funding support!
Very grateful for everything I’ve learned through my first PhD project!

Super cool work!!
Excited to share our #SIGGRAPH2026 paper: Go-with-the-Track!
We utilize point-tracks as spatiotemporal conditioning to precisely insert multiple reference images into generated videos.
