On the 75th anniversary of the stored-program computer, I’m thrilled to announce our next leap forward: OpenAI GPT-4.1, GPT-4.1-mini, and GPT-4.1-nano—now rolling out on Azure AI Foundry.
These models represent something special—a generational advancement in coding, reasoning, and understanding context. With a remarkable 1 million token context window, advanced instruction-following capabilities, and code that truly works, GPT-4.1 is changing what’s possible.
What makes this release particularly exciting is how it empowers developers. You can fine-tune these models directly in Foundry, customizing them to your specific needs, tone, and workflows.
Whether you’re creating agent-based systems, support assistants, or enterprise copilots, GPT-4.1 offers performance and flexibility to bring your vision to life. This is starting to feel like a new foundation for the era of human and AI collaboration. And I can’t wait to see what we build together.
