I just published “The Modern Day Good Product Manager/Bad Product” medium.com/@hemal/the-modern…
Math underpins everything from medicine and physics to finance, engineering, and AI. When there’s advancements in the space, it’s tough to grasp why it’s so revolutionary but the returns that come will be great. So awesome to another strong team hyper focused on it!
Love @warpsciences mission to accelerate drug discovery and build capacity here in America! I couldn't think of a better group to go after it, lfg! 🚀
💥 Introducing Warp Sciences, a new company applying AI and robotics to help the world develop new medicines faster.
We’ve raised a $215M Series A led by @lightspeedvp to bring frontier AI out of the browser and into the lab, and build scientific capacity here in America.
I co-founded Warp with my long-time friend @dpatil, FAIR co-founder @manohar_paluri, and drug hunter Sol Reisberg. The early team is full of incredible people like @bkspears9, who helped achieve Q>1 fusion at LLNL.
Evergreen advice for any role.
As a junior engineer 6 months out of university, I got the best advice of my career: as you become more senior, people will do less and less for you; if you want a thing to happen, you have to do it.
All staff engineer career advice (bring solutions not problems, see risk from the future, effectively manage up) is downstream of this. Downstream of needing to do things to get to outcomes.
OpenAI may have found the ultimate agent eval:
CompanyBench-Max
Give the model a $1T company.
Remove one executive every week.
Measure degradation.
OpenAI top executive exodus in just the last few months:
- Chief Revenue Officer
- Chief Operating Officer yesterday
- Chief Communications Officer
- Chief Marketing Officer
- Chief People Officer
- Head of Robotics
- Head of Science
- Head of Sora
- CTO of Enterprise
- CEO of AGI Deployment
- Head of Preparedness
- Chief Futurist
- Head of Safety
- AI Ethics Lead
everything is fine… IPO prep going great 👍

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!
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!
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 to share Company Knowledge - an evolution of bringing context into ChatGPT, powered by a new retrieval model! Give it a try and let us know what you think: openai.com/index/introducing…
I'm SO excited to have @AriX, @conradev and the entire Software Applications team to OpenAI. These are some of the most thoughtful, and talented builders...watch this space 🚀
We’ve acquired Software Applications Incorporated, the maker of Sky—a natural language interface for Mac.
