OpenAI is transforming its annual developer conference from a single US event into a coordinated global program, bringing hands-on technical training to eight international cities over the next six weeks. The company will host its main DevDay on September 29 in San Francisco, followed by smaller regional DevDay Exchange events in Bengaluru, Tokyo, Seoul, Berlin, Paris, London, São Paulo, and Mexico City.

Why Is OpenAI Expanding DevDay to International Cities?

OpenAI's developer ecosystem has grown far beyond simple language model APIs. The company now offers reasoning models, multimodal systems, real-time voice capabilities, image generation tools, coding assistants, and AI agents that require more complex technical guidance. Developers building with these systems face questions about orchestration, permissions, latency, context management, tool execution, and production deployment that go beyond what API documentation can cover.

Physical developer events become increasingly valuable as AI systems grow more complicated. Engineers can examine real-world implementation patterns, compare different architectural approaches, and discuss production failures that may not appear in technical guides. OpenAI explicitly designed the DevDay Exchange events to include hands-on demonstrations of real-world projects and coding workflows rather than simply presenting product capabilities.

What Will Happen at Each DevDay Exchange Event?

The regional events differ from the flagship San Francisco conference in both scale and focus. While the main DevDay on September 29 will feature Sam Altman's opening keynote, broad technical sessions, and demonstrations aimed at a wide developer audience, the international Exchanges are smaller, hands-on gatherings designed specifically for technical builders and founders.

At each Exchange, developers will work directly with OpenAI product and engineering teams, examine production projects in action, and discuss the workflows being used to build AI applications. The company has specifically highlighted Codex workflows, which represent the intersection between AI model capability and agentic execution, as a key focus area. Modern coding assistants increasingly move beyond generating code to inspecting repositories, modifying files, running commands, executing tests, and interacting with development infrastructure.

How to Prepare for DevDay Events in Your Region

• Identify Your Nearest Event: Check whether your region has a scheduled DevDay Exchange. Asia will host three events (Bengaluru on October 16, Tokyo on October 20, and Seoul on October 22), Europe will have three (Berlin on October 26, Paris on October 28, and London on November 3), and Latin America will have two (São Paulo on November 6 and Mexico City on November 10).
• Prepare Your Technical Questions: Bring specific questions about your production deployment challenges, agent orchestration patterns, or coding workflow integration. The smaller format allows for direct conversation with OpenAI teams rather than one-way presentations.
• Review Recent API Updates: The compressed schedule means new capabilities announced at the September 29 San Francisco event will be discussed at regional Exchanges just 17 days later, while the announcements are still fresh and directly applicable to your work.
• Connect with Local Developers: These events function as regional hubs where you can meet other engineers and founders building AI products in your market, creating networking opportunities beyond OpenAI's direct guidance.

What Is the Geographic Distribution of These Events?

The location strategy reveals OpenAI's prioritization of major technology markets. Asia and Europe together account for six of the eight announced international locations, representing 75 percent of the program. Bengaluru provides access to one of the world's largest software development and technology services ecosystems, while Tokyo and Seoul extend the program into major East Asian technology markets with substantial developer communities and enterprise demand for AI infrastructure.

The European sequence moves through Berlin, Paris, and London, three cities with significant concentrations of startups, research organizations, large enterprises, and AI developers. São Paulo and Mexico City provide the Latin American component, giving OpenAI two major regional hubs rather than treating the expansion as primarily a US-Europe-Asia program. Notably, no 2026 Exchange has been announced for Africa, the Middle East, or Oceania.

Why Is the Schedule So Compressed?

All eight international events will occur within a 25-day window, with an average interval of approximately 3.6 days between events. This unusually tight schedule makes the Exchanges function as a coordinated international program rather than unrelated community meetups. The compressed timeline also allows OpenAI to carry technical themes introduced at the San Francisco DevDay directly into regional developer communities while they remain current.

If major API, agent, coding, or model capabilities are introduced during the September 29 San Francisco event, the Exchange program begins just 17 days later in Bengaluru. This timing allows regional events to function as a practical deployment layer for new developer technology, enabling engineers to learn about and implement new capabilities in their local context shortly after the flagship announcement.

How Does This Reflect Broader Changes in OpenAI's Developer Strategy?

The DevDay expansion signals a fundamental shift in how OpenAI engages with its developer community. Rather than concentrating major developer interaction around one annual US event, the company is creating a distributed international layer around its increasingly large API, agent, and coding ecosystem. The original DevDay format concentrated developers, OpenAI engineers, and product teams in a single physical location, making San Francisco the main venue for product announcements and direct technical interaction.

The 2026 structure preserves that flagship event but adds a second layer through DevDay Exchange, effectively extending the conference cycle for another six weeks. This approach acknowledges that developers in different markets face different deployment challenges, regulatory environments, and infrastructure constraints. By bringing OpenAI teams directly to regional hubs, the company can provide more localized guidance while still maintaining a coordinated global narrative around new capabilities and best practices.

The San Francisco DevDay itself takes place on September 29, with the opening keynote scheduled for 10:00 a.m. Pacific Time and livestreamed for developers unable to attend in person. In-person registration costs $650 for invited attendees, while the keynote livestream remains freely accessible. Other sessions are expected to be recorded and made available after the event, creating three different access levels: the flagship physical event, the global livestream, and the smaller regional Exchange events.
