OpenAI is preparing to host its **DevDay 2026** on Tuesday, September 29, at Fort Mason in San Francisco. The event will feature a keynote speech by Sam Altman, scheduled for 10:00 AM Pacific Time, which is 7:00 PM in metropolitan France. The keynote will be broadcast live on OpenAI’s French website, and the company is expected to announce more than twenty new products or features, including a highly anticipated AI agent named Aeon. Throughout the day, the event will include technical sessions, product demonstrations, and workshops. A reception is planned for 7:00 PM local time, and the program will continue until then. For those who might forget the event’s start time, attendees can leave their first and last names along with an email address to receive a notification about an hour before the keynote begins. According to reports from American media, OpenAI is working on a continuously active AI agent capable of performing tasks such as booking a trip, paying bills, or canceling subscriptions on behalf of users. This agent is expected to be based on the GPT-6 Astra model. However, the GPT-6.1 Astra version, which was originally scheduled to launch in October, has been delayed due to security concerns that have not yet been resolved. OpenAI has also hired Peter Steinberger, the creator of the open-source AI agent called OpenClaw. The company is facing increasing competition in the AI agent space, where Meta’s **Muse** has become popular, reaching the top of the App Store with around 600,000 daily users in the U.S. Google’s **Gemini Spark** is already integrated with services like Uber and Spotify. Another competitor, **Instinct**, which is accessible through iMessage, recently raised one billion dollars in funding. Meanwhile, Anthropic has recently released two new models: **Claude Opus 5.5** and **Sonnet 5.5**.
