If we ultimately make it off the planet in any significant numbers and duration, people will eventually assume the garden of Eden story was written as an allegory about Earth.

Excited to announce our tutorial: "Future of Work in the Age of LLMs" at #ACL2026 in San Diego, July 2! 🌴
There's a lot of speculation about AI and the future of human work. Our tutorial unpacks it from four angles:
→ The landscape of human work
→ How to build LLMs to augment real-world workflows
→ How to evaluate these LLMs
→ The future of work with LLMs/LLM-based agents

@kohjingyu should get one for the lounge

[Kyunghyun Cho @kchonyc]

i just finished teaching <Fundamentals of Machine Learning> for computer science seniors. last time i taught this course, it was titled <Introduction to Machine Learning>, it was pre-ChatGPT and it was pre-pandemic. in other words, i taught this course in the old world, and i was suddenly asked to teach this course in this brave new world.

it was an amazing experience, and i want to share a quick thought about my experience teaching an introductory machine learning course in this new era of industralized software engineering.

the link to the blog is in a reply.

I'm joining Carnegie Mellon's CS Department (and HCII by courtesy) as an assistant professor in Fall 2027!

I'll be recruiting PhD students next cycle. If you're interested in AI systems or human-AI collaboration, list me in your application. Stay tuned for more about my new lab!

[Leena Mathur @lmathur_]

@michaelryan207 @KnightHennessy congrats!!

[Rowan Zellers @rown]

We are so back!

[Mira Murati @miramurati]

Today we're sharing our work on interaction models. A new class of model trained from scratch to handle real-time interaction natively, instead of gluing it onto a turn-based one.

Jensen Huang, Founder and CEO of @NVIDIA, delivered the keynote at Carnegie Mellon’s 2026 Commencement and received an honorary Doctor of Science and Technology degree. His work has helped shape modern computing and the era of #AI. More from Commencement: https://t.co/12Loke7GUC

Huge news for us!
There is so much incredible work our researchers are doing, and we know this transformational gift from Mary and Mark Stevens will shape the future of computing and AI.  @gauravsukhatme

Tokens are not a universal unit of data.

In our new work on Compute Optimal Tokenization, we show that when adapting scaling recipes across tokenizers, bytes are the more stable unit. And the compute-optimal compression rate is not necessarily what today’s BPE tokenizers use.

New paper! https://t.co/1ETmDt0ZB8

This tackles a puzzle we found during the training of Olmo 3: how could two models with nearly identical short-context performance (and trained on the same data!) behave completely differently after long context extension?

[Reid Wiseman @astro_reid]

Only one chance in this lifetime…

Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him.

I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

@lucy_x_shi @richardxp888 Amazing work and analysis!

1/ We just released π0.7 — a steerable generalist robot model with emergent capabilities.
I want to share a bit of the backstory, because π0.7 taught me something surprising about where robot learning is heading. A thread on bittersweet lessons 🧵

Welcome home Reid, Victor, Christina, and Jeremy! 🫶

The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.
