AI can give researchers more freedom to pursue ideas that once felt too unexpected, too ambitious, or too time-consuming to explore. For Fields Medal recipient Terence Tao, that means more room to experiment, test “crazier” paths, and discover what might otherwise stay out of reach. In conversation with OpenAI’s Mark Chen, Terence reflects on a future where AI reduces the cognitive friction of research, helps preserve the paths behind discovery, and expands what mathematicians and scientists can attempt.

We’re taking steps to accelerate defensive progress in biology: - Launching Rosalind Biodefense to help trusted builders develop new biodefense and pandemic preparedness capabilities.
 - Expanding trusted access to GPT-Rosalind for select U.S. government and allied partners supporting public health and biodefense missions.
 Advances in biology can strengthen our ability to prevent, detect, and respond to biological threats. 

 Our goal is to help build a more robust ecosystem – giving trusted defenders frontier AI to develop and operate new defenses for public health and biodefense. https://lnkd.in/g54MBUn7

Congratulations to Fidji Simo and Sarah Friar on being named to Fortune’s Most Powerful Women list. We’re proud to see their leadership and impact recognized as they help us shape how AI benefits people and businesses everywhere. https://lnkd.in/evX8v7TZ 

At OpenAI Frontiers in San Francisco and London, we brought together leaders from across the globe to share how they’re putting AI to work across industries. Teams shared how they’re moving from experimentation to real-world deployment, using AI to rethink products, workflows, and customer experiences. We also heard from builders and executives on what it takes to bring AI into organizations responsibly, securely, and at scale. A highlight from the series: Sarah Friar and Sam Altman in conversation on what comes next as AI becomes part of how companies operate at scale. Now we're bringing Frontiers to Asia, we look forward to meeting with leaders in Tokyo and Seoul this week!

OpenAI has been recognized as a Leader in the Gartner® Magic Quadrant™ for Enterprise AI Coding Agents. Enterprises are entering a new era of software development, moving from AI-assisted coding to agentic systems that can take on more complex work. We’re focused on helping organizations make that shift with Codex, and have the governance, security, and control they need to adopt it with confidence. We’re still early in this journey, but we’re excited by the progress our teams and customers are making with Codex, and by the future of agentic software development ahead. https://lnkd.in/eEZvA4YB

Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946. For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids. An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better. This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics. The proof came from a general-purpose reasoning model, not a system built specifically to solve math problems or this problem in particular, and represents an important milestone for the math and AI communities. This result points to something larger: AI systems are becoming capable of holding together long, difficult chains of reasoning, connecting ideas across distant fields, and surfacing paths researchers may not have explored. We believe those same abilities will soon accelerate work in biology, physics, engineering, and medicine. That future still depends on human judgment. Expertise becomes more valuable, not less. AI can help search, suggest, and verify. People choose the problems that matter, interpret the results, and decide what questions to pursue next. https://lnkd.in/e8YC-4i8

People are generating over 1.5 billion images a week in ChatGPT. On the OpenAI Podcast, Product lead Adele Li, researcher Kenji Hata and host Andrew Mayne trace the progress from the early DALL-E days and dive into the latest capabilities, including better text rendering, photorealism, multilingual support, world knowledge, aspect ratios, and character consistency. Listen as they also explore what comes next as image generation models evolve into more capable creative assistants. https://lnkd.in/dr9D6-8i

Real-time voice AI only feels natural when conversations move at the speed of speech. We rebuilt parts of our voice infrastructure to make ChatGPT voice and the Realtime API faster and more reliable for people around the world. Here’s how we keep voice interactions feeling responsive at global scale: https://lnkd.in/g4CxdT4H

ChatGPT adoption broadened in early 2026, becoming a more mainstream tool, used by a broader mix of people, in more countries, and for increasingly recurring tasks. We take a look at how usage is expanding across age, gender, and geography, and how people are turning to ChatGPT for more specialized, repeatable work. https://lnkd.in/gyPWzaMn
