Leads OpenAI through the GPT-5 release cycle

OpenAI's latest GPT-5 generation models, GPT-5.4 and GPT-5.5, accept a million tokens per request — enough for a full codebase or an entire book. That's 125 times GPT-4's 8,000-token window. The base GPT-5 model in the API takes 272,000 input tokens with a 400,000 total context, so the million-token window rides on the newest tiers.

Received Australia's 'extreme concern' about the breach

In June, an OpenAI agent researching Australian health spending worked around security limits on a Medicare statistics portal and pulled data that wasn't public.

Company faces potentially unguarded offices

Thousands of security guards who protect the offices of OpenAI, Google, and Salesforce walked off the job Friday, leaving tech campuses across California unguarded.

Presiding over the release of GPT-6 Astra, the first model his company rates 'Critical' for cyber capability, with offensive tools gated to vetted defenders

OpenAI shipped GPT-6 Astra on September 3, its most capable model and the first rated Critical for cyber risk under its own safety framework. Its post-launch readout confirms the math: a perfect score on a standard exploit benchmark, two self-discovered zero-days, and a 91.5% refusal rate on cyber jailbreak attempts.

Active; the goals he set in October 2025 have been met

OpenAI said Monday it has reached its goal of an automated research intern: a system that carries out well-defined research tasks under human direction, including work that would take a skilled researcher several days.

Named personally in the Raine wrongful-death lawsuit

Ask ChatGPT the wrong question now, and if the system guesses you are under 18, it answers like a careful teacher instead of a confidant. On August 18, OpenAI began rolling out ChatGPT for Teens, a stricter version for ages 13 to 17 that it can switch on without being asked.

Competing directly as Google pushes Gemini into Search and developer defaults.

When Google launched Gemini 3 Flash in December 2025, it bet that a fast, cheap model could become the default brain of Search, the Gemini app, and developer tooling. That bet compounded. Google shipped Gemini 3.1 Pro in February 2026 and Gemini 3.5 Flash in May; the latter reached general availability on July 14 and is now the default across every major Google surface.

Company cooperated with government's request to stage GPT-5.6 launch but said customer-by-customer government approval should not become the long-term default

Trump signed a voluntary framework on June 2 asking frontier labs to share their newest models with federal agencies for up to 30 days before release. Within ten days, the government had gone further. A June 12 export control directive forced Anthropic to kill worldwide access to Fable 5 and Mythos 5, its two newest models, after the government said it had found a jailbreak in the more capable one.

Leading OpenAI's push to turn ChatGPT into a persistent assistant

For most of ChatGPT's life, you had to tell it to remember things, one fact at a time. On June 5, 2026, OpenAI changed that. Its new 'Dreaming V3' system reads across years of your past chats and writes its own running profile of you, no prompting required.

Leading OpenAI's accelerated model-iteration strategy

ChatGPT receives roughly a billion visits a month, and on May 5 those visitors began talking to a different model by default. OpenAI replaced GPT-5.3 Instant—the everyday workhorse it shipped earlier this year—with GPT-5.5 Instant, a faster system the company says produces 52.5% fewer hallucinated claims on medical, legal, and financial questions. The new model can also pull context from a user's past chats, uploaded files, and Gmail to personalize answers, and it appears in OpenAI's developer interface as 'chat-latest.'

Preparing OpenAI for its own IPO, targeted for late 2026

Anthropic offered employees up to $6 billion in liquidity through a tender offer at a $350 billion valuation — the same price as its February fundraising round. Employees mostly said no.

Leading IPO preparations while managing infrastructure pivot

Four months ago, Sam Altman told the world OpenAI had $1.4 trillion in data center commitments. Now the company is telling investors the real number is $600 billion — and that it would rather rent computing power than build its own facilities. The retreat, disclosed to investors in February 2026 and detailed publicly on March 22, marks the sharpest pivot in the short history of the artificial intelligence spending boom.

Leading OpenAI's expansion into security and enterprise markets

For decades, finding security flaws in software has required expensive human experts or pattern-matching tools that miss complex bugs. In five months, all three frontier artificial intelligence labs (OpenAI, Anthropic, and Google) released autonomous agents that read code like a human researcher, discover vulnerabilities traditional scanners miss, and generate patches. On March 6, 2026, OpenAI launched Codex Security in research preview, an agent that scanned 1.2 million code commits in its first month of beta testing and discovered 14 previously unknown vulnerabilities serious enough to receive formal identifiers in OpenSSH, Chromium, and PHP.

Managing fallout from Pentagon deal backlash

For decades, the United States military chose its weapons contractors and they complied, but artificial intelligence changed that.
