GPT-5.4 Thinking System Card
Introduction GPT‑5.4 Thinking is the latest reasoning model in the GPT‑5 series, and explained in our blog. The comprehensive safety mitigation approach for this model is similar to previous models in this series, but 5.4 Thinking is the first general purpose model to have implemented mitigations
Introducing GPT-5.4
Today, we’re releasing GPT‑5.4 in ChatGPT (as GPT‑5.4 Thinking), the API, and Codex. It’s our most capable and efficient frontier model for professional work. We’re also releasing GPT‑5.4 Pro in ChatGPT and the API, for people who want maximum performance on complex tasks. GPT‑5.4 brings together t
Reasoning models struggle to control their chains of thought, and that’s good
As AI agents become capable of carrying out increasingly complex and autonomous tasks, maintaining reliable oversight of their behavior becomes more important. Consistent with our principle of iterative deployment, we study how systems behave in real-world settings and continuously refine safeguards
Ensuring AI use in education leads to opportunity
Of the 900 million people who use ChatGPT each week, college-age adults are the biggest adopters among age groups. How they learn to use AI will increasingly shape their future opportunities, and education systems are uniquely positioned to help. Much of modern education was built to help students
Introducing ChatGPT for Excel and new financial data integrations

The five AI value models driving business reinvention
Most organizations still manage AI as a series of use cases: a pilot here, a workflow there, a promising tool inside one function. That approach can generate local wins but it rarely transforms how a business creates value. It is akin to creating interactive banners and drip email campaigns with th
Introducing the Adoption news channel
A new phase of enterprise AI is underway. For the past two years, the story was largely about the pace of the technology: new models, new capabilities, new breakthroughs and demonstrations of what AI could do. That phase mattered. But it also created an information environment dominated by technica
Extending single-minus amplitudes to gravitons
We’ve published a new preprint studying scattering amplitudes in quantum gravity, extending recent results obtained for gluons to the gravitational setting. The work shows that a class of graviton interactions long assumed to vanish can in fact arise under well-defined kinematic conditions. The prep
Understanding AI and learning outcomes
Education is one of AI’s most promising frontiers. With tools like ChatGPT, personalized learning support can be available to any student, anywhere, at any time. But the education sector is still early in its understanding of the impact of AI on learning outcomes. Last year, our team set out to st
