Introducing GPT‑5.4—our most capable and efficient frontier model for professional work. GPT‑5.4 brings together the best of our recent advances in reasoning, coding, and agentic workflows into a single frontier model. It's our most factual and efficient model: fewer tokens, faster speed. GPT-5.4 Thinking and GPT-5.4 Pro are rolling out now in ChatGPT. GPT-5.4 is also now available in the API and Codex. https://lnkd.in/gWvcSwZV

The Codex app is now on Windows. Built for Windows environments, with built-in sandboxing for building with agents: • Work with multiple agents in parallel • Manage long-running tasks • Review diffs in one place • Stay in PowerShell, or easily switch to WSL if needed To bring Codex to Windows, we built the first Windows-native agent sandbox, using OS-level controls like restricted tokens, filesystem ACLs, and dedicated sandbox users to safely run agents on Windows machines. Codex is available through ChatGPT Plus, Pro, Business, Enterprise, and Edu subscriptions. Download the Codex app for Windows: https://lnkd.in/guyKdhDY

AI demand is growing rapidly as more people and businesses use AI to learn, build, and get work done every day. Today we’re announcing $110B in new investment, with support from SoftBank Group Corp., NVIDIA, and Amazon, to help scale the infrastructure needed to meet that demand and make AI more accessible, reliable, and useful for everyone. Hundreds of millions of people are using ChatGPT each week, and as usage grows, continued investment in compute, distribution, and partnerships is essential to bringing frontier AI to more communities worldwide. https://lnkd.in/gZ65Cjrh

We’re partnering with the Council of Fashion Designers of America (CFDA) to launch The Innovation Hub, a new two-year initiative designed to help American designers and brands explore the creative and business potential of AI. The program will pair promising CFDA members with leading AI builders to co-create tools that address real-world challenges facing fashion today in ways that are practical, responsible, and scalable. Our goal is to show how emerging technologies can meaningfully support creativity, strengthen business longevity, and drive positive change across the industry, while keeping designers firmly in the driver’s seat. https://lnkd.in/eZkxWB4e

Stargate is the umbrella brand for our compute strategy. It’s about mobilizing the full ecosystem to deliver a step-change in global AI compute — and over the past few quarters that vision has become reality. Since announcing Stargate in January 2025, OpenAI has expanded from a mostly single-provider model to a broad partner network across clouds, silicon, and infrastructure: SoftBank, NVIDIA, AMD, Broadcom, Oracle, Microsoft, AWS, CoreWeave, and Cerebras. Demand is compounding, and no single provider, chip, or cloud can carry the load. A diversified compute model is the only way to scale at the pace AI requires. We exited 2025 with ~2 GW of available compute and a model designed to scale: long-term capacity agreements, purpose-built colo deployments, and deep collaboration on next-generation datacenter design. Compute leadership is the foundation of research and product velocity — and Stargate is how we build what comes next.

We’re committing $7.5M to The Alignment Project, a global fund for independent alignment research created by the UK AI Security Institute. As AI capabilities continue to advance, building a robust, diverse, and independent alignment ecosystem is essential. We look forward to continuing to collaborate with the broader research community as the field advances. https://lnkd.in/gd-Vkg_g

A study published today showed LLM-assisted clinical decision support may have prevented major complications in two-thirds of neurosurgery patients. It has long been my thesis that advanced AI could show the most uplift in low-resource settings, which is why I jumped at the chance to lend support to the work of the talented teams at Edward Francis Small Teaching Hospital and MGB Neurosurgery, and am so encouraged by the study published today by Saksham Gupta, Zsombor Gal, Dr John N JABANG NEUROSURGEON and colleagues in Neurosurgery (in comments). This study evaluated OpenAI models as a clinical decision support tool in low-resource surgical settings. The study also found that the models improved clinical plan quality in 60% of the mock rounds interactions, with medical officers benefitting more than nurses (21% vs. 6.5% improvement), likely because they handle broader diagnostic and management responsibilities. Errors were reduced from 33% to 0% in case testing. Here is the most incredible part: of the 14 clinical interventions across 9 patients attributed to LLM suggestions, 6 potentially prevented serious complications! The study was small, and the paper notes the limitations, but even given these, the results were so encouraging that they inspired the birth of the West Africa AI Neurosurgery Consortium, which is expanding the work or the study to 5 countries in West Africa to further validate these findings for neurosurgery in low-resource settings. This is exactly the type of setting where advanced AI could have the greatest marginal impact: a facility with just 3 neurosurgeons serving an entire country of 3 million, where postoperative care for patients as complex as brain tumors, spinal disease, and penetrating trauma falls to junior doctors and nurses managing complex patients.
