OpenAI announces global DevDay expansion with events across eight international cities
OpenAI is expanding its DevDay developer program beyond San Francisco, adding eight international DevDay Exchange events across Asia, Europe and Latin America between October and November 2026.
The expansion follows the main OpenAI DevDay 2026, scheduled for September 29 at Fort Mason in San Francisco, where the company will host its opening keynote, technical sessions, demonstrations and workshops for developers building with OpenAI models and APIs.
The international program will then move through Bengaluru, Tokyo, Seoul, Berlin, Paris, London, São Paulo and Mexico City, creating a sequence of smaller regional events focused on technical builders rather than reproducing the San Francisco conference at full scale.
OpenAI describes the DevDay Exchanges as hands-on gatherings where developers and technical founders can work with OpenAI teams, examine production projects and discuss the workflows being used to build AI applications.
The structure indicates a broader change in OpenAI's developer strategy: instead of 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.
DEV DAY EVENT | DATE | REGION |
San Francisco DevDay | September 29 | North America |
Bengaluru | October 16 | Asia |
Tokyo | October 20 | Asia |
Seoul | October 22 | Asia |
Berlin | October 26 | Europe |
Paris | October 28 | Europe |
London | November 3 | Europe |
São Paulo | November 6 | Latin America |
Mexico City | November 10 | Latin America |

OPENAI IS TURNING DEVDAY INTO A MULTI-CITY DEVELOPER PROGRAM
The original DevDay format concentrated developers, OpenAI engineers and product teams in a single physical event, making San Francisco the main location for product announcements, demonstrations and direct technical interaction.
The 2026 structure keeps that flagship event but adds a second layer through DevDay Exchange, effectively extending the conference cycle for another six weeks.
The September 29 event remains the central OpenAI DevDay, including the opening keynote featuring Sam Altman, technical breakouts and broader product programming, while the international Exchanges are smaller events designed around technical sessions, real-world projects, Codex workflows, hands-on guidance and direct conversations with OpenAI product and engineering teams.
OpenAI is therefore not simply livestreaming the same conference internationally. It is building a sequence of local developer environments where the company can interact with teams already deploying AI products in different markets.

THE EIGHT CITIES CREATE THREE CLEAR INTERNATIONAL CLUSTERS
The location distribution is concentrated rather than geographically uniform, with three events in Asia, three in Europe and two in Latin America.
REGION | CITIES | EVENTS | SHARE OF INTERNATIONAL EVENTS |
Asia | Bengaluru, Tokyo, Seoul | 3 | 37.5% |
Europe | Berlin, Paris, London | 3 | 37.5% |
Latin America | São Paulo, Mexico City | 2 | 25.0% |
Africa | None announced | 0 | 0% |
Middle East | None announced | 0 | 0% |
Oceania | None announced | 0 | 0% |
Asia and Europe together account for six of the eight announced international locations, representing 75% of the program.
Bengaluru gives OpenAI direct access to one of the world's largest software-development and technology-services ecosystems, while Tokyo and Seoul extend the program into two major East Asian technology markets with large developer communities and substantial enterprise demand for AI infrastructure.
The European sequence moves through Berlin, Paris and London, three cities with substantial concentrations of startups, research organizations, large enterprises and AI developers.
São Paulo and Mexico City provide the Latin American component and give OpenAI two major regional hubs rather than treating the expansion as a US-Europe-Asia program.
No 2026 Exchange has currently been announced for Africa, the Middle East or Oceania.

THE INTERNATIONAL TOUR RUNS FOR LESS THAN FOUR WEEKS
The schedule is unusually compressed. The first Exchange takes place in Bengaluru on October 16, while the final event currently listed is Mexico City on November 10, placing all eight international events inside a 25-day window.
STAGE | DATE | DAYS AFTER PREVIOUS EVENT |
Bengaluru | Oct. 16 | — |
Tokyo | Oct. 20 | 4 |
Seoul | Oct. 22 | 2 |
Berlin | Oct. 26 | 4 |
Paris | Oct. 28 | 2 |
London | Nov. 3 | 6 |
São Paulo | Nov. 6 | 3 |
Mexico City | Nov. 10 | 4 |
The average interval between events is approximately 3.6 days, a cadence that makes the Exchanges look like a coordinated international program rather than unrelated community meetups.
The compressed schedule also gives OpenAI the ability to carry technical themes introduced in San Francisco directly into regional developer communities while they remain current.
If major API, agent, coding or model capabilities are introduced during the September DevDay, the Exchange program begins only 17 days later, allowing regional events to function as a practical deployment layer for new developer technology.

DEVDAY 2026 REMAINS THE CENTER OF THE PROGRAM
OpenAI DevDay itself takes place on September 29 in San Francisco.
The opening keynote is scheduled for 10:00 a.m. Pacific Time and will be livestreamed, allowing developers who are not attending physically to follow the main announcements.
The San Francisco program includes technical sessions covering OpenAI APIs and tools, hands-on demonstrations, workshops and direct interaction with teams building the company's developer products.
Attendance is oriented toward engineers, technical founders, researchers and technical leaders actively building AI products.
The in-person registration price is $650 for invited attendees, while the keynote livestream remains freely accessible, with other sessions expected to be recorded and made available after the event.
The combination creates three different access levels: the flagship physical event, the global livestream and the smaller regional Exchange events.

THE EXPANSION ARRIVES AS OPENAI'S DEVELOPER PLATFORM BECOMES MUCH BROADER
The significance of DevDay Exchange is easier to understand when compared with the widening scope of OpenAI's developer ecosystem.
The company is no longer primarily asking developers to send prompts to a language-model endpoint. Its platform increasingly includes reasoning models, multimodal models, real-time voice, image generation, coding systems, agents, tools and application integrations.
That changes the type of technical support developers need because agent systems and multimodal applications introduce more complicated questions involving orchestration, permissions, latency, context management, tool execution, reliability, evaluation and production deployment.
Physical developer events become more useful as those systems become more complex because engineers can compare architectures, examine practical implementation patterns and discuss failures that may not appear in API documentation.
OpenAI explicitly says the Exchange events will include real-world projects and Codex workflows rather than only presentations about product capabilities, moving DevDay closer to an implementation-oriented developer program.
··········
CODEX IS LIKELY TO BE AN IMPORTANT PART OF THE EXCHANGES
OpenAI specifically identifies Codex workflows among the subjects that developers will encounter at DevDay Exchange.
That is notable because AI coding products increasingly sit at the intersection between model capability and agentic execution.
A conventional coding assistant primarily generates or explains code, while a more agentic coding environment can inspect repositories, modify files, run commands, execute tests and interact with development infrastructure.
For developers, the relevant questions consequently move beyond model benchmark performance to repository permissions, execution environments, review workflows, tool access, failure recovery and integration with existing engineering processes.
DevDay Exchanges give OpenAI an environment to demonstrate those workflows directly with teams using the technology in production.
··········
THE FORMAT ALSO HELPS OPENAI COMPETE FOR DEVELOPERS
Developer ecosystems create a form of platform competition that extends beyond raw model performance.
A company can offer a technically strong model and still struggle to retain developers if integration is difficult, documentation is weak or production workflows require excessive engineering work, while a platform deeply embedded in development environments can maintain usage even when competing models improve.
This makes developer relationships strategically important for OpenAI as it competes not only with other model providers but also with platforms offering their own APIs, agent frameworks, coding systems and enterprise integrations.
DevDay Exchange gives OpenAI another channel for reducing the distance between its engineering teams and developers deciding which AI infrastructure to build around.
The events can also generate feedback before product decisions become fixed, exposing OpenAI to infrastructure, localization and enterprise requirements that vary between teams in Bengaluru, Berlin, São Paulo and other markets.

DATA STUDIOS MAPS THE EXPANSION AS A FOUR-STAGE DEVELOPER FUNNEL
The 2026 structure can be interpreted as a four-stage developer-engagement system.
STAGE | FORMAT | FUNCTION |
1 | San Francisco DevDay | Major announcements and flagship technical program |
2 | Global livestream | Large-scale distribution of announcements |
3 | DevDay Exchange | Regional technical interaction and implementation |
4 | Developer community | Continued discussion, experimentation and deployment |
The first stage concentrates attention, the second distributes the announcements globally without requiring physical attendance, and the third creates smaller technical environments where builders can work more directly with OpenAI teams.
The fourth extends engagement after the events through developer communities, documentation and ongoing product usage.
This structure is more scalable than attempting to reproduce the full San Francisco conference independently in every region and gives OpenAI a way to distinguish between developers who primarily want information and those who require deeper technical interaction.
··········
DEVDAY HAS BECOME AN IMPORTANT PRODUCT-LAUNCH WINDOW FOR OPENAI
Previous DevDay events have increasingly served as launch points for important developer products.
At DevDay 2025, OpenAI introduced or expanded products including Apps in ChatGPT, AgentKit, Sora 2 in the API and new Codex capabilities.
That history means the September 29 keynote will be watched not simply as a developer conference but as a potential product-announcement event.
OpenAI has not specified that any particular unannounced model or product will launch at DevDay 2026, so the relevant confirmed information remains the event structure rather than speculation about future releases.
The Exchange schedule nevertheless creates an operational pattern in which major developer capabilities presented in San Francisco can move almost immediately into regional workshops and technical discussions during October and November.
That makes the international expansion potentially more important than a conventional event tour because it creates an infrastructure for distributing new OpenAI developer technology after launch.
··········
THE GLOBAL EXPANSION REDUCES DEVDAY'S DEPENDENCE ON SAN FRANCISCO
San Francisco remains the center of OpenAI's developer event strategy, but the 2026 structure reduces the requirement that international builders travel to the United States to interact physically with OpenAI teams.
The difference is especially significant for developers in Asia, Europe and Latin America, where travel cost and visa requirements can make participation in a single US conference impractical even for teams actively building on the platform.
A local Exchange does not reproduce every component of DevDay, but it provides a more accessible technical touchpoint.
The result is a hybrid model in which major announcements remain centralized while technical engagement becomes more distributed, mirroring the way AI platforms themselves are evolving: model development may remain concentrated, while deployment occurs across thousands of companies, countries and industries.
··········
OPENAI IS BUILDING A GLOBAL DISTRIBUTION LAYER AROUND ITS DEVELOPER PLATFORM
The eight-city expansion changes DevDay from a single annual gathering into a broader developer program spanning nine physical locations when San Francisco is included.
The geography remains selective, but the structure provides OpenAI with direct technical access to developer communities across three international regions within weeks of its flagship conference.
The most important part of the expansion is therefore not simply the number of events but the timing: OpenAI can announce new developer technology in San Francisco on September 29 and begin discussing its implementation with regional builders less than three weeks later.
As OpenAI's platform expands from individual model APIs into coding agents, multimodal systems and increasingly complex application infrastructure, that direct connection between product teams and developers can become as strategically important as the models themselves.
