OpenAI

@OpenAI

We’re working with an independent advisory group of mathematicians to help OpenAI responsibly share advances in AI and mathematics. The group will advise on how we assess and communicate new mathematical results, uphold academic and professional standards, and build tools that support mathematical research and learning. Through this work, we want mathematicians to be at the center of shaping how AI supports mathematical understanding and how its benefits reach the wider community. https://t.co/QCMFLFlIv8

On FrontierCode 1.1, our benchmark for real-world engineering tasks, Grok 4.7 scores slightly below Grok 4.6. While strong on many hard tasks, it tends to over scope on others, leading it to trail behind Grok 4.6 in the aggregate. Read more: https://t.co/PgginMwMNp

Grok 4.7 is now available in Devin. On FrontierCode 1.1, Grok 4.7 scores 59.4% on Extended. In our evaluation, we see the model performs very well on hard backend engineering tasks. https://t.co/qbliTyU1Dt

With devin ssh, you can remote into Devin’s developer environment and use it as your own. Explore and edit code directly, launch dev servers and forward ports to test Devin’s work, or scp files back from the VM to you. And when you’re done, you can /handoff back to your machine using the CLI.

Grounded Confidence is here for Extract! 🦙 When your agents and workflows depend on extracted data, you need to know how accurate that data is. We’ve added confidence scores to give you a better read on extraction accuracy, field by field. Use them to decide which results your app can accept automatically and which need human review. Available on Cost Effective, Agentic, and Agentic Plus. Try it out on your docs -> https://t.co/v28mAfRAet

Motionographer®

@motionographer

U.S. Against the World | Good Secrets Seventy percent hip hop. Thirty percent punk rock. For HBO Originals’ U.S. Against the World, Good Secrets channels the U.S. Men’s National Team’s rebellious energy into scratched film, collage, and graffiti. A handcrafted visual language built around the team’s grit and ambition. That approach extends from the title sequence across the entire graphics package, with custom maps, game clocks, scorecards, and archival treatments carrying the same raw, physical texture. Created alongside Park Stories’ Rand Getlin and Janina Pelayo and Outpost’s Lucas Harger.
