    I’ve worked with @kevinweil and @manohar_paluri and they are amazing. So great to see them go after a big and important problem to accelerate scientific discovery to find new medicines. I’m excited to play a very small part as an angel investor and help them in their journey.

    💥 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.

    Excited to meet builders at @spc_india in Bangalore on Sep 9th.
    Prateek Mehta @prateekmehta42
    Super excited to have @snsf at @spc_india for a '-1' chat! Srinivas was the CTO of B2B Applications at @OpenAI, and before that led Engineering for over a decade at @Meta. He is a real OG of what is now the edge of the frontier. A quest that started at IIT Madras, and went planet-scale! How does one person build at multiple frontiers? How do you build at that scale, and at speed? What did the early days look like in these rooms? This will be a real builders' chat! Apply to attend. We have limited slots. Link in comments.

    Introducing GPT-5.5 — a new class of intelligence for real work. It’s our smartest and most intuitive model yet: stronger at agentic coding, computer use, scientific research, and multi-step work across tools. You can give it ambiguous, messy, real-world tasks and trust it to plan, use tools, check its work, and keep going. Now rolling out in ChatGPT and Codex. Coming to API very soon.

    Very excited to launch workspace agents in ChatGPT today. Teams can now create shared agents powered by Codex that handle complex tasks and long-running workflows. We have always wanted to build a product that can go beyond helping individuals be more productive to also helping teams be more effective. Workspace agents are designed for that - they can gather context from the right systems, follow team processes, ask for human approval when needed, and keep work moving across tools/teams. Available in research preview in ChatGPT Business, Enterprise, Edu, and Teachers plans. Huge congrats @tarstarr @christinaahuang @_rohanmehta and the workspace agents team!

    After 3 incredible years, I am leaving OpenAI at the end of next week. I shared my decision with the OpenAI leadership team at the start of the month and here is a shorter version of what I shared with my team earlier this week. === Hi Team, I have decided to leave OpenAI. The last three years have been an incredible journey that felt more like ten. Leading the b2b engineering team has been an enormous privilege. With the recent/upcoming product launches, this felt like the right time to step back. I will also fondly remember my prior role leading the Applied Engineering team, from when it was ~40 people on a single floor in the 575 office, when I first started. We shipped some of the fastest-growing products in history, like ChatGPT and the API, with no real playbook to guide us. This was only possible because of the incredible team we built - you are the most passionate, dedicated, and hard-working colleagues I have ever worked with. You all have inspired me so much, and I’m so proud of what we have built together. I can’t thank you enough! I am so grateful to @sama @gdb @fidjissimo and the rest of the OpenAI leadership for this opportunity of a lifetime. I will cherish this time forever during this historic period for technology and society, and I wish you all the very best for the future. I am looking forward to spending some much-needed time with my aging parents in India before deciding what’s next. Thanks again. It has been a privilege to be on this journey with you. ===

    Today we launched a major update to the OpenAI Agents SDK to help developers build and deploy long-running, durable agents in production. You can now build your own Codex-style agents using powerful primitives for modern agents - file and computer use, skills, memory and compaction. The harness and compute are now split - you can bring your own sandbox or use partners like Blaxel, Cloudflare, Daytona, E2B, Modal, Runloop, and Vercel for container execution. The harness is open-source and so you can inspect and customize it for your needs. Try it out! Really fantastic work by @stevendcoffey and the API team!

    Really sad to see this attack at Sam’s home. Violence like this is completely unacceptable. I’ve known @sama and worked with him closely. He is a visionary, thoughtful and deeply committed leader. Sending Sam, Ollie, and their family strength and support.
