(1/n) Robots must learn to interact with articulated objects. While training in simulation is promising, high-quality articulated assets remain scarce. We present Infinigen-Sim: procedurally generated articulated simulation assets for robot learning. 🧵
Can Visual Language Models (VLMs) do non-local visual reasoning, i.e., piecing together scattered visual evidence? Humans do this to search images, compare objects, and trace lines. Despite recent advances, our new evaluation suggests most VLMs cannot do these consistently. 1/6
lol, amateurs. And that's without my 5y of DotA Allstars (v1)

imagination is generative; control is 3D
We've released our paper "Generating 3D-Consistent Videos from Unposed Internet Photos"! Video models like Luma generate pretty videos, but sometimes struggle with 3D consistency. We can do better by scaling them with 3D-aware objectives. 1/N page: genechou.com/kfcw
📢 Excited to share that I’ll be joining @UCSanDiego @HDSIUCSD as an Assistant Professor in January 2026! My lab will focus on efficient AI. I'm recruiting PhD students from HDSI/CSE in the Fall 2024 cycle and also looking for RAs/interns! More info see zhijianliu.com.
🌟New LLM Safety Benchmark🌟 🥺SORRY-Bench: Systematically Evaluating LLM Safety Refusal Behaviors (sorry-bench.github.io) LLMs are trained to refuse unsafe user requests. 🤨But... are they able to give advice on adult content ♂️♀️🌈? 🧐What about generating erotic stories 📖?…
How much value does your fine-tuning add? Believe it or not, just 1 bit 🤏 Thrilled to unveil BitDelta, a super simple yet effective method for compressing fine-tuning deltas into a single bit while barely touching performance. This approach slashes storage and GPU memory demands…
Data drives progress in computer vision. We introduce Infinigen: a generator of unlimited high-quality 3D data. 100% procedural, no external assets, no AI. Free and open source. Intro video: youtu.be/6tgspeI-GHY Code: github.com/princeton-vl/i… CVPR23: Wed 4:30PM, Poster 27
