Precision is vital for robotic manipulation. Language reasoning (VLAs) are limited in their precision. Pixel generation (WAMs) are overkill.

GAMs are an alternative to both. It uses 3D grounding models instead of language models of video generators.

VLAs? WAMs? Are language and video models the right foundations for robotics?

Introducing Grounded Action Model (GAM): a new paradigm that builds robot foundation models on top of a pretrained 3D grounding model.

Ground first. Then learn to act. 🧵👇

My students and I will be doing real robot demos at my talk at the Embodied Reasoning workshop #CVPR2026 today at Room 605 from 9:30-10:20am. Come by!

We believe agents for the open web should be built in the open!

We are releasing MolmoWeb, a completely reproducible SOTA Web Agent!

Open Data, Open Weights, Open Code!

Today we're releasing MolmoWeb, an open source agent that can navigate + complete tasks in a browser on your behalf.

Built on Molmo 2 in 4B & 8B sizes, it sets a new open-weight SOTA across four major web-agent benchmarks & even surpasses agents built on proprietary models. 🧵

We are releasing MolmoBot! We challenge the assumption that sim-to-real requires real-world finetuning. Our robot models beat strong baselines with no real world data.

With enough diversity and scale in simulation, zero-shot transfer can actually work—across both static and mobile manipulation.

Similar to all our projects, everything is open sourced.

Today, a step forward in open robotics - our results show that sim-to-real zero shot transfer for manipulation is possible. MolmoBot is our open model suite for robotics, trained entirely in simulation on MolmoSpaces.🧵
