Precise Event startDate schema is withheld so the page does not overstate an expected or windowed date.

This is an expected date. Use reminders and monitoring, but verify the source before making travel, purchase, publication, or staffing decisions.

Primary citation

The current date signal points to openai.com. The source URL is shown visibly on the page so readers can verify late changes instead of relying only on the timer.

Freshness and review

Source policy was reviewed on 2026-04-30. Live countdown values are render-time snapshots; editorial source fields update when the tracked event dataset changes.

Operational detail

The record includes a source-local time and timezone, so city conversion pages can show a real local start time.

Weak-date handling

The page stays crawlable and useful, but confidence copy and schema posture are deliberately weaker than a confirmed event page.

What this countdown tracks

The clock above counts down to OpenAI DevDay 2027 on Tuesday, October 5, 2027, OpenAI's annual developer conference, expected to return to San Francisco with a hybrid in-person and livestream format.

About this event

OpenAI DevDay is the company's flagship developer event, established in 2023 and now the most closely-watched single-vendor AI developer conference on the calendar. The event combines an opening keynote from Sam Altman and OpenAI's product and research leadership with hands-on developer sessions, partner showcases, and live demos of new model and platform capabilities. DevDay is consistently the venue at which OpenAI announces its most significant API and platform features each year.

DevDay 2027 lands roughly two years into OpenAI's broader platform shift toward agents, applications inside ChatGPT, and the Apps SDK launched at DevDay 2025. The 2026 edition (October 6, 2026, Fort Mason, San Francisco) is expected to introduce GPT-6 or its successor, expanded AgentKit capabilities, and continued evolution of Codex GA and the Realtime API. DevDay 2027 will inherit and build on those announcements, with OpenAI's stated emphasis on enterprise reliability, agent orchestration, and the Sora video and image generation API maturing across the year.

What to expect

Per OpenAI's stated cadence and the precedent of prior DevDays, expect the opening keynote to centre on the next-generation frontier model (GPT-7 or similar successor in the post-GPT-6 cycle), substantial AgentKit updates, expanded Realtime and Voice API capabilities, deeper Apps in ChatGPT integration, Sora 3 or its successor in the API, and updates to the Responses API and Assistants framework. Anticipated themes include enterprise tooling for evaluations and observability, continued model-distillation announcements (smaller, faster, cheaper variants of frontier models), and partner case studies from major OpenAI customers like Klarna, Lowe's, and Mercado Libre.

Past editions

OpenAI DevDay 2026 is expected at Fort Mason in San Francisco on October 6, 2026.
OpenAI DevDay 2025 launched Apps in ChatGPT, AgentKit, Codex GA, GPT-5 Pro API, gpt-realtime-mini, and Sora 2 in the API.
OpenAI DevDay 2024 introduced the Realtime API, Prompt Caching, Model Distillation, and Vision in fine-tuning.
OpenAI DevDay 2023 was the inaugural event, launching GPTs, the Assistants API, GPT-4 Turbo, and the GPT Store.

How to watch

Sessions are recorded and posted to YouTube and the OpenAI developer documentation hub within hours, with code samples and API reference updates published the same day.
