I'm in Pittsburgh for IROS 2026 and will be presenting our work "Generalizable Robotic Insertion with World Models" tomorrow morning. Stop by our poster at G11 for a chat about world models, robot learning, and beyond! ✨

Super excited to share the last paper of my PhD: "Hallucination in World Models is Predictable and Preventable" ✨ We train a 350M-parameter generative world model on a large dataset spanning 210 tasks and show that we can predict *when* hallucination will happen and use that info to fix it! 🧵1/n

Interested in ✨world models✨? I just open-sourced an implementation of the Dreamer 4 world model. It's in PyTorch and comes with a pretrained model + a neat little web interface that lets you interact with any of 30 DMControl tasks that I trained it on! Link: github.com/nicklashanse...

I'm in San Diego for NeurIPS! (...I live here, but I'm also attending NeurIPS) I will be speaking at the Embodied World Models workshop on Saturday 10.00-10.30am. Let me know if you are around and would like to chat, or if you just need a food recc 🫶 (pictured: la jolla)

🎉 New work: “Learning Massively Multitask World Models for Continuous Control” We introduce MMBench: a 200-task RL benchmark, and Newt: a language-conditioned multitask world model trained with large-scale online RL. www.nicklashansen.com/NewtWM/ Code, checkpoints, dataset etc. are open-source!

I am in Honolulu for ICCV 2025 and will be speaking at the Reliable and Interactable World Models workshop at 11.20am tomorrow! Let me know if you're around and want to chat about RL, world models, or anything else :-)

The sim2real demo had some mixed success, hampered primarily by the lighting conditions of the outdoors. At least it worked sometimes! Hindsight says that despite the weather, low-cost nature, only 1 hour of training, anything working is a miracle

I will be in Singapore 🇸🇬 this week for ICLR 2025! Let me know if you're around and want to chat about RL, world models, LLMs, or anything else :-) I am presenting two papers on model-based RL and also speaking at the World Models @ ICLR workshop on Monday. (Photo is from my last trip to Singapore)

I finally joined 🦋! Some of you may recognize me from other sites. Here's a quick intro for new connections: 👋 I work on RL, world models, and generalization in decision-making. I'm perhaps most well known for my work on "TD-MPC2: Scalable, Robust World Models for Continuous Control" www.tdmpc2.com

Visualization of domains for which TD-MPC2 has been applied, including locomotion, manipulation, dexterous hands, humanoids, autonomous racing.
