OpenAI announces DevDay 2025: the developer event will take place on October 6 in San Francisco

The most anticipated annual event for the OpenAI community returns with announcements, technical keynotes, and over 1,500 selected participants

OpenAI has officially announced the dates and format of DevDay 2025, its annual event dedicated to the global community of developers and AI technology integrators. The event will take place on October 6, 2025, at Fort Mason in San Francisco, and is expected to be the largest edition organized so far.

Over 1,500 developers will be selected to attend the conference in person, which will also be streamed live and documented with on-demand videos accessible to the public in the following days. The event will be led by the company's top executives, including CEO Sam Altman and President Greg Brockman, featuring technical sessions, demos, hands-on labs, and strategic announcements about the future of the OpenAI platform.

Registration is open until July 30 and participants will be selected by lottery

Those wishing to attend in person can submit their application until July 30, 2025, via the official OpenAI website. There will be no technical merit-based selection: participants will be chosen by lottery. Selected applicants will receive confirmation in mid-August, with one week to confirm their attendance and complete registration.

Participation entails a cost of $650 USD, which covers the full day of conferences, access to hands-on sessions, and the exhibition area.

All major content will still be accessible remotely. In particular, the opening keynote will be live-streamed on openai.com, and full recordings will be made available afterward.

DevDay will be an opportunity to announce new models, features, and developer tools

The event is not just a meeting point for technicians, businesses, and innovators, but also a key moment to reveal new technologies coming to the platform. While the official agenda has not yet been released, it is expected to feature previews or official launches of features currently in beta, such as:

• Expansions of ChatGPT agent, including extensions and dynamic automations

• Potential announcements of new models like GPT‑5, GPT‑4o reasoning, or enterprise-specific releases

• Multimedia integrations, especially updates to Sora 2, the in-house video generation technology

In parallel, DevDay will offer practical workshops designed for those building plugins, custom APIs, AI-driven tools, or integrating AI into their own workflows.

The latest platform features hint at the themes that may be explored during the event

In recent months, OpenAI has introduced several features focused on personalizing the user experience, which may form part of the DevDay 2025 agenda. These include:

• New ChatGPT personality modes (Listener, Cynic, Sage, Robot)

• The collaborative “Study Together” mode for structured learning

• New recap features, multi-step agents, and function orchestration already being tested within the o3 model

These innovations indicate a shift toward a more modular, integrable, and adaptive platform, which could be consolidated with targeted announcements during the event.

DevDay is not just a showcase—it’s a thermometer of developer-side AI evolution

While DevDay is often perceived as a stage for announcements, its real value lies in offering concrete tools for building intelligent applications, with an operational focus and direct dialogue with those who build software and large-scale solutions.

OpenAI presents it as a space for collaboration among engineers, partners, entrepreneurs, and researchers—an opportunity to redefine how AI APIs are adopted in production, education, healthcare, industrial, or creative environments.

The ecosystem around ChatGPT, Codex, Whisper, and GPT APIs is no longer limited to experimental projects: it is now a central component of global companies' digital infrastructure.
