Check out PEVA 🌎, our recent attempt to build a world model for human body control.
What would a World Model look like if we start from a real embodied agent acting in the real world?. It has to have: 1) A real, physically grounded and complex action space—not just abstract control signals. 2) Diverse, real-life scenarios and activities. Or in short:.It has to

(Un)surprisingly @ylecun didn't mind 😅 and so did @trevordarrell which was a bit reassuring. Anyway--it's nice to see the outcome is an award. if you're interested to hear more, come tomorrow (Sat) to Oral Session 4B (ExHall A2, 1:00-2:15) and visit poster #396 (Hall D, 5-7pm).

NWM intersects with multiple communities (video generation, 3D vision, robotics, RL, representation learning. ) and it seemed to equally piss off everyone. I remember I told @GaoyueZhou and @dans_t123 - "lower expectations, this paper is a 99% reject".

Navigation World Models won the Best Paper Honorable Mention Award at #CVPR2025 ☺️ . It is my first postdoc paper since joining Yann's lab at @AIatMeta, so I am very excited. It was also extremely fun working with @GaoyueZhou, @dans_t123, @trevordarrell (and @ylecun) . Fun story:.
Congratulations to the #CVPR2025 Honorable Mentions for Best Paper!.@GoogleDeepMind, @UCBerkeley, @UMich, @AIatMeta, @nyuniversity, @berkeley_ai, #AllenInstituteforAI, @UW, #UniversityCollegeLondon, @UniversityLeeds, @ZJU_China, @NTUsg, @PKU1898, @Huawei Singapore Research Center

Need a strong feature extractor for your upcoming NeurIPS paper? we got you 😉.
We are open-sourcing all the models in Web-SSL, from ViT-L to ViT-7B! .It was super fun to train and play with these massive ViTs. Models: Github: Huge credit to @DavidJFan for putting these models together!.

Excited to share that our paper on Navigation World Models was selected for an Oral presentation at CVPR!.Code & models:.
Happy to share our new work on Navigation World Models! 🔥🔥 . Navigation is a fundamental skill of agents with visual-motor capabilities. We train a single World Model across multiple environments and diverse agent data. w/ @GaoyueZhou, Danny Tran, @trevordarrell and @ylecun.

FAIR is probably the only lab outside of academia where research projects can start like this.
[7/8] This side project started in October when @TongPetersb, @_amirbar, and I were thinking about the rise of CLIP as a popular vision encoder for MLLMs. The community often assumes that language supervision is the primary reason for CLIP's strong performance. However, we.

CLIP is arguably the leading pretraining paradigm in computer vision. In a new preprint, we show that vision-only SSL models trained on web data can match CLIP on VQA tasks, despite not using language. Paper: Project Page:
