OpenAI rolled back GPT-4o citing sycophancy—just as our research predicted. Short-term feedback teaches AI to sound nice... and systematically misaligns it! Our solution: RLHS, training AI with simulated hindsight feedback for long-term alignment! 👉 arxiv.org/abs/2501.08617

Congrats to Andrea Bajcsy (Andrea Bajcsy) on receiving the NSF CAREER award! 👏 Her work: “Formalizing Open World Safety for Interactive Robots,” explores how robots make safe decisions beyond collision avoidance. Read about it and her education plans: loom.ly/59evuD0

Huge thanks to everyone who made NESCW Columbia University awesome! The students and postdocs brought their A-game and created an incredible energy through talks and poster sessions—this is how a research community should always feel! Thrilled to host next year Princeton University! #NESCW2026 📸👇

How can we boost the visual generalization of VLAs 𝑤𝑖𝑡ℎ𝑜𝑢𝑡 𝑎𝑛𝑦 𝑓𝑖𝑛𝑒-𝑡𝑢𝑛𝑖𝑛𝑔? Asher Hancock will be presenting at #ICRA2025 on Wed in the Vision-Language-Action Models session (WeDT21): Run-Time Observation Interventions Make Vision-Language-Action Models More

Can AI keep you safe at 200 mph? We pushed the limits on the world-class racing sim Assetto Corsa🏁 When danger strikes, our AI copilot smoothly adjusts your steering, gas & brakes faster than you blink, keeping you on track, in control and crash-free🛡️✨ See it in action!👇🧵

🤔 Feel like your AI is bullshitting you? It’s not just you. 🚨 We quantified machine bullshit 💩 Turns out, aligning LLMs to be "helpful" via human feedback actually teaches them to bullshit—and Chain-of-Thought reasoning just makes it worse! 🔥 Time to rethink AI alignment.
