OpenAI is preparing for a major day of announcements, with its annual developer conference set to put the spotlight on AI agents, ChatGPT, developer tools, and potentially new hardware. Rumors point to more than 20 product announcements, although the full list has not been officially confirmed.
OpenAI DevDay 2026 is scheduled for September 29 in San Francisco. The official event website confirms that CEO Sam Altman will deliver the opening keynote, with technical sessions, hands-on demonstrations, and developer-focused announcements planned throughout the day.
Among the rumored announcements are a new “O” agent, a potential $500 subscription tier, a hardware debut, and a unified ChatGPT and ChatGPT Work experience. There is also speculation about future GPT-6.1 or GPT-6.5 Astra models, although those specific model announcements remain unconfirmed.
OpenAI DevDay 2026: What to Expect
The biggest talking point ahead of DevDay is the possibility of OpenAI introducing more than 20 products, features, and other updates.
If the rumored scale of the event is accurate, the announcements could extend beyond new AI models to include ChatGPT features, agent capabilities, developer APIs, subscription plans, and hardware.
However, the figure of 20 or more announcements has not been confirmed by OpenAI. The company’s official DevDay website describes a program centered on new technology, technical sessions, demonstrations, and developer workshops.
2. The mysterious “O” agent
One of the rumored announcements is an AI agent referred to as “O.”
While details remain scarce, an agent-focused announcement would fit into the broader shift toward AI systems that can perform tasks rather than simply respond to prompts.
Potential areas of interest include task automation, multistep workflows, and the ability to interact with software and online services. OpenAI has not publicly confirmed the name, capabilities, or launch date of the rumored O agent.
3. GPT-6.1 or GPT-6.5 Astra: A new model remains uncertain
A new GPT-6-series model is another possibility being discussed ahead of the event.
The rumored names include GPT-6.1 Astra and GPT-6.5 Astra. Neither model announcement should be treated as confirmed for DevDay.
There is also uncertainty surrounding Astra’s release plans. Reuters reported on September 28 that OpenAI had shelved a planned October release following safety concerns identified during internal testing.
That report makes it particularly important to distinguish speculation about a new Astra release from an official product announcement.
4. A new $500 subscription tier
OpenAI could also introduce a new subscription plan priced at $500 per month, according to the rumors surrounding DevDay.
Such a plan would represent a substantial increase over the company’s existing consumer subscription options. Its potential audience could include professional developers, businesses, and users who rely heavily on advanced AI tools.
The price, included features, usage limits, and intended audience have not been officially confirmed. It is also unclear whether the rumored tier would be a ChatGPT subscription, a business offering, or a separate product.
5. OpenAI’s first hardware device could make its debut
Hardware could be another major part of the event.
OpenAI has been associated with efforts to develop AI-focused hardware, raising questions about whether the company will introduce a physical device designed around its AI services.
A hardware announcement could potentially reveal how OpenAI wants people to interact with AI beyond traditional websites, desktop applications, and smartphones.
For now, the rumored DevDay debut remains unconfirmed. The device’s design, capabilities, availability, and pricing have not been established by the official event announcement.
6. ChatGPT and ChatGPT Work could merge
Another significant rumor suggests OpenAI could bring ChatGPT and ChatGPT Work together into a unified experience.
A combined platform could make it easier for users to move between everyday conversations and professional tasks without switching between separate products.
Possible areas of integration include document creation, research, coding, workplace collaboration, and AI-powered task automation. However, the precise scope of the rumored merger remains unclear.
OpenAI has not confirmed whether ChatGPT Work will be merged into the main ChatGPT application or whether the change would involve a redesigned interface, new subscription plans, or a broader product restructuring.
OpenAI DevDay 2026: Confirmed vs. rumored announcements

ChatGPT and ChatGPT Work merger | Unconfirmed |
The confirmed details above are based on OpenAI’s official DevDay 2026 announcement . The other items are rumors and should not be interpreted as a confirmed launch schedule.
When does OpenAI DevDay 2026 begin?
OpenAI DevDay takes place on Tuesday, September 29, at Fort Mason in San Francisco. The opening keynote is scheduled for 10 a.m. Pacific Time, featuring Sam Altman.
For viewers in India, that translates to 10:30 p.m. IST on September 29.
The keynote will be livestreamed, allowing people who are not attending the in-person event to follow the announcements.
What could this mean for ChatGPT users?
The rumored announcements point toward several areas of development: more capable AI agents, additional subscription options, deeper workplace integration, and potentially a new way to interact with OpenAI’s technology through dedicated hardware.
For developers, the event could also bring new APIs, tools, and demonstrations that make it easier to build applications around OpenAI’s models.
Still, the distinction between confirmed information and speculation matters. Until OpenAI reveals its announcements, the rumored product count, subscription pricing, hardware debut, and future model releases should be treated as possibilities rather than finalized plans.
OpenAI DevDay 2026 is happening today, September 29. The keynote should provide a clearer picture of the company’s upcoming products, its plans for AI agents, and the next phase of its ChatGPT ecosystem.
