I’m excited to share that I’ll be joining OpenAI and look forward to working with the exceptional team there.

It was a difficult decision to move on. I’m incredibly proud of the amazing team at Google and everything we’ve built together. It has been an honor and a pleasure to work with all of you.

@julien_c you can train with your shoes, that's their trick

@jachiam0 Thanks for saying it Josh !

We’re releasing prompt-based teen safety policies for gpt-oss-safeguard.

They’re designed to help you identify and moderate teen-specific content, and turn safety requirements into classifiers for real-time filtering or offline analysis.

that's a big milestone: looking forward to know what our European community is going to build with this 🩶 - share you best European use cases!

[Tibo @thsottiaux]

Three million people are now using Codex weekly - up from two million a little under a month ago. Incredible to see the growth. Thank you to all of you and to the ecosystem we’re part of. To celebrate, we’re resetting rate limits so you can keep building, and we’ll reset them every additional 1M users until we reach 10M, so we can keep celebrating along the way.

Enjoy and thank you!

@rlacombe 🤣

[Ludovic Peran @LudovicPeran]

Open question to the safety community: are there teen-specific safety classifiers for content detection?

Roblox Guard has a 'Child Exploitation' category.. Anything else?
