researchers these days are spoiled by how good simulators are. i remember habitat...

[Fei-Fei Li @drfeifei]

1/N Long horizon, complex tasks that truly matter in everyday life are not solved problems by today’s robotics, requiring planning, object detection, object manipulation, and failure recovery.

That's why Stanford's BEHAVIOR Challenge is back for year 2! Last year, the winning solution reached only 12.4% full task success. This year, the BEHAVIOR challenge has more tasks, better evaluation, and is easier to use. 🚨

⏰ Submission deadline: 10/16/2026
📣 Winners announced: 11/04/2026
🏆 Prize pool: $11,000

Okay so, we just found that over 50 papers published at @Neurips 2025 have AI hallucinations

I don't think people realize how bad the slop is right now

It's not just that researchers from @GoogleDeepMind, @Meta, @MIT, @Cambridge_Uni are using AI - they allowed LLMs to generate hallucinations in their papers and didn't notice at all.

It's insane that these made it through peer review👇

[Fei-Fei Li @drfeifei]

This came as a total surprise this morning. Very humbled… 🙏 AI is built by generations of technologists, starting with the daring question of “can machines think?” by Alan Turing. It will be further developed, used and governed by many and all of us! Let’s keep our AI mission human-centered for the benefit of humanity! And I can’t wait to see where AI’s next frontier - spatial intelligence - will be taking us!

A couple of days ago, I presented our 1st place solution for the 2025 BEHAVIOR Challenge at @NeurIPSConf . Now, we've open-sourced our solution: code, model weights, and a detailed tech report.
Let me unpack what we did 👇

Ruohan has been a great advisor and friend throughout the BEHAVIOR project (that's 4 years of working together on the same thing!), and now he's starting his own group at Northwestern. I 100% recommend reaching out to him if you're interested in doing a Robotics / AI PhD!

[Ruohan Zhang @RuohanZhang76]

I will join Northwestern University Computer Science as an Assistant Professor in Fall 2026!

I am actively recruiting PhD students and seeking collaborations in robotics, human-robot interaction, brain-computer interfaces, cognitive science, societal impact of AI & automation, and AI for art & design.

Please see the recruitment announcement on my personal website, and feel free to reach out!

[The Humanoid Hub @TheHumanoidHub]

The 2025 BEHAVIOR Challenge, launched by @drfeifei's team at Stanford, is a global competition to train robots in household tasks, testing reasoning, navigation, and manipulation in simulated homes.

⦿ 50 tasks, 1,000 activities (e.g., cooking, cleaning)
⦿ 10,000 expert demos (1,200+ hours)
⦿ Baselines methods like ACT, OpenVLA, and π0

The submission deadline is November 15th.

@MelihKarakelle @argeolog_ Ustteki resimdekiler burada impact wrench diye geciyor ucu 1/2” lokma icin, normal impact driverlara kiyasla daha yuksek torklu. Hatta high-torque versiyonlari var lastikcilerin kullandigi, 1500 ft-lbs tork veriyor impact driverin 250 ft-lbs yerine. $180 falan ama guzel alet :)

Check out BRS, especially our setup for teleoperating simulated AND real robots to solve BEHAVIOR-1K tasks! In these realistic tasks, key objects are at various horizontal and vertical distances that make most robot embodiments and teleop systems unsuitable. JoyLo to the rescue!

@Stone_Tao @tarikkelestemur DVC is a great tool for versioning assets and selectively running pipelines that need to be rerun. We have been using it for 3 years for BEHAVIOR-1K for our internal asset pipelines. That said you still need to give it a storage backend for it to store its data on, e.g. gcloud

@moli208 @tubasmemory @ecetheceo @efescott44 Hicbir sigorta sirketi police satmiyorsa nereden sigorta alabilir var olan ev sahipleri? Yanan yerlerin bazilarinda kodamanlar da oturuyor diye etkilenen herkesin sifirdan ev yaptiracak parasi oldugunu dusunmuyorsunuz heralde.

[Cem Gökmen @cgokmenAI]

@moli208 @tubasmemory @ecetheceo @efescott44 bu tarz yangin vs kapsamayan police satiyor. Eyaletin neredeyse tamami yangin tehlikesi olan yerlerde tamamen yanici ahsap evler, 40 milyon kisi sigortalayabilecegini dusunerek oturdugu evleri simdi sigortalayamaz hale geliyor. Nereye ev yapmasinlar, butun Kaliforniya’ya mi?

[Justus Mattern @MatternJustus]

The only piece of advice I give to undergrads that want to get into research is to cold email PhD students with a good track record.
Most undergrads are bottlenecked by research ideas whereas good PhD students have way too many ideas that they cannot execute. If you can code reasonably well, PhD students will be more than happy to work with you

[Cem Gökmen @cgokmenAI]

@Stone_Tao Major props to you for running this evaluation so quickly 👍 Glad to be able to discuss some of the surprising claims on this release!
