Just learned:
Software engineers used to do manual data labeling at Scale AI while Alex Wang was CEO. After he left, new leadership joined, and were HORRIFIED to learn this. Stopped it ASAP
Now at Meta, software engineers are assigned manual data labeling... see the pattern?

AI is advancing quickly. Society’s ability to manage its risks must advance just as fast.
Today we’re sharing our vision for AI Resilience, with more than $130M in initial grants underway across bio-resilience, cyber-resilience, AI model safety, and AI’s impact on young people: openaifoundation.org/news/re…

don't really care about winning a Nobel Prize
care about helping you do it ❤️
AI can give researchers the freedom to pursue “crazier” ideas.
For Terence Tao, AI creates more room to experiment, test unexpected paths, and discover what might otherwise stay out of reach.

Codex app has gotten insanely fast lately, the performance issues have decreased massively - swapping chats is nearly instant.
you can really really tell that the entire team is dogfooding this app

When I wake up in the middle of the night, I want to fully optimize my waking moments and get as much done as I can. That’s why I have Codex projected above my bed at all times.
It’s the only way.

Proud to see our work on agent security @openai highlighted in Forbes. Securing AI agents means bringing identity, credential, and access controls directly into the developer workflow, and Codex is a major step in that direction.

I’ve been working on bringing Codex to iOS and I am thrilled to finally be able to share it with you all!
I happen to be OOO today for some personal stuff so I’ll post more thoughts later, but wanted to share this just to say it’s a great experience on an iPad with a keyboard :)

this $CBRS is showing that frontier computing is exciting. i restarted $QCLS with my partner @csvoss to create the world's first fully photonic computer for AI
companies like @Etched @neurophos @OLIXComputing @taalas_inc are also leading the pack. We want everyone to win!

“it’s called ‘vibe coding.’ by the way, have you tried MCP?”
you jolt awake. you’ve fallen asleep over your laptop at the OpenAI Language Model Hackathon, February 12–13, 2020. the startup ecosystem doesn’t even know about GPT-3. it was all a dream

me every time I attempt to direct codex by asking “can we <do something>?” and it says “yes” instead of doing it
We have a record of Cleopatra's handrwiting: γινέσθωι "make it happen", appending a tax exemption.
