With GPT-5.4, we built a purpose built skill to help sharpen your paper submissions with editorial feedback, and more careful argument factual review.
It brings advanced intelligence directly into the revision process. Give it a try, and let us know what you think!

💥 New in Prism today: Paper Review, an AI workflow for reviewing technical and scientific papers.
This is the opposite of AI slop: we're using AI to improve scientific rigor, correctness, and reproducibility.

Rare to find founders with deep care for craft and a clear belief that design is about trust, intent, and outcomes. Perfect moment to rethink design in an AI world. Grateful to be along for the ride, and more importantly, excited to watch this team cook!

I’m thrilled to announce we’ve raised $44M to build a new home for product design. Meet @noondesign.
No workflow is more broken and fragmented in 2026 than the product designers’. The very same people who care most about building software don’t have software purpose built for them. @kushagrasinha7 and I have lived this problem first hand as designers ourselves.
That’s why we built Noon. The first product design tool that works entirely on your product code, so you can design not only how a product looks, but also how it works. With AI at its core that works in seconds, not minutes.
For the first time, you can create, iterate, build, test and ship. All in one canvas. No translations or roundtrips to the codebase and back.
Comment “Get Noon” and we’ll get you on the list for early access.

This is the real story - OpenAI is starting to give scientists superpowers and accelerate real scientific discovery.
Excited to watch what @kevinweil is building with OpenAI for Science.
The rest is noise.
We are excited to share a new paper solving three further problems due to Erdős; in each case the solution was found by an internal model at OpenAI. Each proof is short and elegant, and the paper is available here: arxiv.org/pdf/2603.29961

ChatGPT for Excel is here!
GPT-5.4 is shockingly good at performing Excel manipulations. In particular, it's been impressive at handling work when thrown into complex existing spreadsheets. Available for Plus, Pro, Enterprise, Business, and Edu users!

Introducing Prism powered by Codex — now bringing compute, analysis and creation in one surface for Scientists & Researchers.
Excited to see how this can accelerate faster hypothesis testing, and new idea generation. Give it a try and let us know what you think!

🧵1/ We've brought the most advanced AI to Prism by introducing Codex to Prism. Prism is already the best place for scientific writing to happen—and with Codex, now you can write, compute, analyze, and iterate all in one place.

Holiday Zooms are elite content. Talking corporate strategy with childhood soccer participation trophies in the background and a parent off screen yells asking if they should cut the crusts off your sandwich.

So excited about this - introducing a Slack connector inside of ChatGPT (one of the most useful connectors for my day to day), AND, having ChatGPT inside of Slack helps me pull information where the conversation is happening.
I’d love to hear how you use them!🚀
🚀 Big news: The ChatGPT app for Slack is here.
With Slack’s new Real-Time Search API, the ChatGPT app for Slack brings the power of ChatGPT into a dedicated Slack sidebar – a space for you to ask questions, brainstorm ideas, draft content and solve problems. This is just the beginning of a smarter way to work together. 💡
Check it out in Slack Marketplace today. #DF25 sforce.co/3W61s6v
