💡Don't miss our workshop today about physical appearance modeling and relighting in the age of Generative AI at #CVPR 2026 🚀

Time: June 4th, 2026 (14:00 - 17:30)
Location: Room 108, Colorado Convention Center, CVPR 2026

Orbit enables RL post-training for trillion-parameter LLMs on a single GPU node, with an extremely small train-rollout gap. A big step toward making post-training for frontier models accessible!

Excited to share our work EgoRelight (SIGGRAPH 2026 Journal Track) ✨

We explore how to bring remote people into your physical surroundings as photorealistic, relightable avatars — instead of keeping everyone inside a fully virtual world.

Congratulations @marc_habermann for receiving the Eurographics 2026 Young Researcher Award!!

@yxue_yxue Bro is this me actually? Suddenly see this - why it looks so much like me and unlike me 🤣

Happy to share our #CVPR2026 Oral "Relightable Holoported Characters"!

Capture a person once, relight them in any environment — from any viewpoint ✨

Editing appearance, geometry, lighting with precision is easy with a 3D scene representation. But it's so much more difficult with just an image or photograph.

Enter IntrinsicEdit: Precise generative image manipulation in intrinsic space (@siggraph 2025)!

I will always be a Mav for life, but had to come support my guy 77 @luka7doncic in the first game of his new chapter!

Want to drive your photoreal full-body avatar solely from an egocentric camera?

Check out our #SIGGRAPHAsia 2024 work EgoAvatar!

One unexpected negative impact here lmao: one of my dudes was using Sky for the voiceover of his #SIGGRAPHAsia video submission and on the last day of the deadline when he wanted to edit something, Sky was off😅

[Sam Altman @sama]

in regards to recent stuff about how openai handles equity:

we have never clawed back anyone's vested equity, nor will we do that if people do not sign a separation agreement (or don't agree to a non-disparagement agreement). vested equity is vested equity, full stop.

there was a provision about potential equity cancellation in our previous exit docs; although we never clawed anything back, it should never have been something we had in any documents or communication. this is on me and one of the few times i've been genuinely embarrassed running openai; i did not know this was happening and i should have.

the team was already in the process of fixing the standard exit paperwork over the past month or so. if any former employee who signed one of those old agreements is worried about it, they can contact me and we'll fix that too. very sorry about this.

If your model is weak, your paper might end up getting more citations because people are always happy to include your model as a baseline.
