🚀 Introducing 𝐀𝐮𝐭𝐨𝐀𝐠𝐞𝐧𝐭𝟎: An 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐑𝐮𝐧𝐭𝐢𝐦𝐞 for Safe Closed-Loop Driving! Most autonomous driving research focuses on optimizing E2E driving policies. However, in long-tail, 𝐥𝐚𝐫𝐠𝐞𝐥𝐲 𝐮𝐧𝐯𝐞𝐫𝐢𝐟𝐢𝐚𝐛𝐥𝐞 driving environments, stronger policies alone cannot ensure 𝐬𝐚𝐟𝐞 𝐚𝐧𝐝 𝐫𝐨𝐛𝐮𝐬𝐭 𝐜𝐥𝐨𝐬𝐞𝐝-𝐥𝐨𝐨𝐩 𝐞𝐱𝐞𝐜𝐮𝐭𝐢𝐨𝐧. In 𝐀𝐮𝐭𝐨𝐀𝐠𝐞𝐧𝐭𝟎, we reformulate traditional runtime monitoring as an 𝐚𝐠𝐞𝐧𝐭𝐢𝐜 𝐫𝐮𝐧𝐭𝐢𝐦𝐞 𝐡𝐚𝐫𝐧𝐞𝐬𝐬 that reasons about 𝐰𝐡𝐞𝐧 𝐭𝐨 𝐢𝐧𝐭𝐞𝐫𝐯𝐞𝐧𝐞 and 𝐡𝐨𝐰 𝐭𝐨 𝐫𝐞𝐜𝐨𝐯𝐞𝐫, leveraging two key capabilities: 1️⃣ 𝐒𝐜𝐞𝐧𝐞 𝐂𝐨𝐧𝐭𝐞𝐱𝐭 𝐑𝐞𝐟𝐢𝐧𝐞𝐦𝐞𝐧𝐭 — Leveraging VLM reasoning to refine critical scene context missed by nominal policies, enabling reliable action verification and triggering interventions when nominal policies fail. 2️⃣ 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐑𝐞𝐜𝐨𝐯𝐞𝐫𝐲 𝐋𝐨𝐨𝐩 — Leveraging VLM-guided stochastic optimization to iteratively propose, verify, and refine explainable recovery policies through verifier feedback. 📊 𝐒𝐭𝐫𝐨𝐧𝐠 𝐜𝐥𝐨𝐬𝐞𝐝-𝐥𝐨𝐨𝐩 𝐠𝐚𝐢𝐧𝐬! 𝐀𝐮𝐭𝐨𝐀𝐠𝐞𝐧𝐭𝟎 consistently improves representative E2E driving policies on 𝐅𝐚𝐢𝐥𝟐𝐃𝐫𝐢𝐯𝐞 (up to +37.0 SR) and 𝐍𝐚𝐯𝐒𝐚𝐟𝐞-∞ (up to +32.8 SR), without policy retraining. Our results highlight 𝐚𝐠𝐞𝐧𝐭𝐢𝐜 𝐫𝐮𝐧𝐭𝐢𝐦𝐞 𝐚𝐬 𝐚 𝐜𝐨𝐦𝐩𝐥𝐞𝐦𝐞𝐧𝐭𝐚𝐫𝐲 𝐝𝐢𝐫𝐞𝐜𝐭𝐢𝐨𝐧 𝐭𝐨 𝐬𝐜𝐚𝐥𝐢𝐧𝐠 𝐄𝟐𝐄 𝐝𝐫𝐢𝐯𝐢𝐧𝐠 𝐩𝐨𝐥𝐢𝐜𝐢𝐞𝐬. 🎉 Huge congrats to the amazing team: @jiagengliu02 , @sethzhao506 , @Zewei__Zhou , Alejandro Huerta, Aidan Bayer-Calvert, Yuxin Bao, @DarthUtopian , Robert Spataru, @zijun_cui02 , @yining_hong , @zhoubolei , and Jiaqi Ma! 🛠️ Everything is open-sourced! 🌐 Project: jiagengliu02.github.io/AutoA… ⭐ Code: github.com/jiagengliu02/Auto… 📄 Paper: arxiv.org/abs/2610.18866 #AgenticAI #AutonomousDriving #EndToEndDriving #PhysicalAI

I took this video at IROS’26 in Pittsburgh two days ago. At first glance, it looks like an impressive autonomous humanoid making cocktail drinks. Zoom out, and you see what is really behind it. I have mixed feelings about watching this. 1. Teleoperation is getting remarkably good. Data collection is becoming more accurate, scalable, and immersive. Combined with rapidly improving AI models, I can imagine much of this eventually becoming autonomous. That is exciting, but it also makes the potential impact on human jobs feel much more immediate. 2. But what are we actually seeing in a robot demo? Without proper disclosure or reference, it can be surprisingly difficult to distinguish teleoperation from autonomy. As physical AI attracts more attention and investment, demos need to be much clearer about how much is autonomous and how much is human-controlled. 3. Even “autonomous” demos can be difficult to interpret. Is the robot actually generalizing? Or is it replaying a demonstration, following a scripted trajectory, or overfitting to one carefully prepared environment? A tabletop demo alone often can’t tell us. Maybe the important question for Physical AI is no longer just “Can the robot do it?” It is also: “How did the robot do it, and will it still work when we change the task, objects, or environment?”

I’ll be speaking at #IROS2026 in Pittsburgh this Sunday (Sept. 27) at two workshops! 🤖 Bridging Navigation — 8:45–9:30 AM 🤖 Social Robot Navigation — 11:40–11:55 AM I’ll share our work on scaling long-horizon sidewalk navigation — from learning from fleet data to world models and cross-embodiment. If you’re at IROS, come say hi! Always happy to chat and meet in person.

My first ICLR paper was in 2015: Object Detectors Emerge in Deep Scene CNNs (arxiv.org/pdf/1412.6856). That year, ICLR received 143 submissions and accepted 31 papers; ours was one of 12 oral papers. Fast forward to ICLR 2027: 60,000 abstract submissions. What an incredible journey for ICLR and for the field of AI.

Augmenting multi-agent world models with world state registers! Nice work led by Sicheng and Yuheng.
If multiple agents live in the same world, why should their video streams live in separate memories? Let’s make every player remember the same world state.

Tomorrow (Thursday morning), 9:00–10:30 AM, I'll be at Poster 326 to present our work on a new imitation learning framework, MIMIC, for training a sidewalk autopilot. Stop by if you're attending #ICRA2026 in Vienna: MIMIC (Multi-scale IMItation with Corrective expansions) trains sidewalk autopilots from teleoperation data by expanding corrective behaviors and visual diversity through generative augmentation.

Vista4D pushes toward scalable any-view 4D video reconstruction!
📢 Eyeline Labs and Netflix’s latest research, 🎥Vista4D🎥, accepted at #CVPR2026 as a 🌟Highlight🌟 paper, advances virtual cinematography and scene control with video generation. 🎥 Vista4D synthesizes the dynamic scene represented by an input video from novel camera trajectories and viewpoints by grounding video generation in a 4D point cloud. Our method maintains geometric and physical plausibility under imprecise 4D reconstruction of real-world videos. 🎥 Vista4D unlocks video reshooting beyond camera control. By directly editing the 4D point cloud, our method preserves scene information from casual captures and enables 4D scene editing and recomposition. This work is part of the ongoing research and development at @eyelinestudios and @netflix, and we look forward to seeing its techniques and workflows adopted in future productions. ✊ Kudos to the team: @kuanhenglin, Zhizheng Liu, @pablosalamancal, @yash2kant, @RyanBurgert, @Yuancheng_Xu0, @Koichi_N_, Yiwei Zhao, @zhoubolei, @micahgoldblum, @debfx, @realNingYu 📰 Paper: arxiv.org/pdf/2604.21915 🌐 Project: eyeline-labs.github.io/Vista… ⌨️ Code: github.com/Eyeline-Labs/Vist…
