OpenAI DevDay 2026 is scheduled for September 29 in San Francisco and will bring developers, AI builders and technology enthusiasts together at OpenAI’s annual developer-focused event. CEO Sam Altman will give the opening keynote, and OpenAI will present new developments in its models, APIs, developer tools and AI products.
The keynote is scheduled for 10:30 PM IST on September 29 for viewers in India. OpenAI's official event page confirms that the opening keynote will take place at 10 AM Pacific Time and Sam Altman will be present. The company also confirmed that the keynote will be livestreaming and viewers don’t have to go to the San Francisco event to see the big announcements.
OpenAI DevDay 2026: Date And India Time
OpenAI DevDay 2026 will be held on Tuesday, September 29, at Fort Mason in San Francisco. The event will be in session with technical sessions, demonstrations and workshops on OpenAI developer tools.
The opening keynote begins at 10 AM Pacific Time. For the audience in India, that works out to 10:30 PM IST on September 29. The event will continue in San Francisco all day long with breakout programming after the keynote.
This year’s DevDay occurs at a key time in OpenAI’s product cycle and the company has presented several big developments in the last few weeks of the conference.
How To Watch OpenAI DevDay 2026 Live
OpenAI has confirmed that the opening keynote will be livestreamed and available online for free. Viewers can sign up on the official DevDay website to get a reminder before the keynote starts. OpenAI also promised that other sessions will be recorded and published on its website after the event.
In-person applications for DevDay are closed and OpenAI says tickets will not be available at the venue on the day. But the online keynote is open to everyone.
What Could OpenAI Announce At DevDay 2026?
There are a number of potential announcements being discussed ahead of the conference. These are based on leaks and speculation and not confirmed OpenAI plans, so we shouldn’t take them as guaranteed announcements. To be sure, these announcements are not a sure thing. Seven new developments which should be of interest to keep the keynote audience’s attention, here are some things that are likely to be addressed during the keynote.
1. Further GPT-6 Sol And Luna Expansion
GPT-6 Sol and GPT-6 Luna are no longer just rumours. OpenAI has already released the models in the API while Sol and Luna are also available in ChatGPT Work and Codex. OpenAI describes GPT-6 Sol as a model designed for complex coding and agentic workflows.
DevDay could therefore focus on wider availability, additional integrations, developer capabilities or demonstrations with the GPT-6 family rather than presenting Sol as an entirely new model.
2. Always-On AI Agents
One of the most eagerly awaited rumours is the possibility of a new always-on AI assistant or agent experience. Online reports have linked an “o” assistant to ChatGPT Pro, but this has not been officially confirmed by OpenAI.
If such a product is released, it could represent a shift from the question-and-answer model to AI systems that can remain available for longer-running tasks and workflows. This is, however, very much an open question.
3. Faster AI Responses
Speed is another area worth watching. OpenAI and Cerebras have already demonstrated GPT-5.6 Sol running in Ultrafast mode at up to 750 output tokens per second through Cerebras infrastructure. This technology was available as an OpenAI API service tier, but only for a select number of customers.
DevDay could provide more details about faster inference, new performance tiers or how high-speed models can be used in real-time applications.
4. New ChatGPT Subscription Options
Another option that is being talked about online is a higher-priced ChatGPT subscription tier. Reports have mentioned names and prices like “ChatGPT ProMax” but OpenAI has not officially confirmed such a product.
Any new subscription announcement would likely be closely watched because it could introduce different usage limits, access to advanced models or additional agent and developer capabilities.
5. Major Desktop And ChatGPT Interface Updates
OpenAI could also use DevDay to showcase changes to ChatGPT's desktop experience. The company has increasingly positioned ChatGPT as more than a standard chatbot and has a wide range of features, from coding, browsing, computer use, connected tools and longer-running work.
Developers will want to see if future interface changes make it easier to combine these capabilities within a single workflow.
6. Closer ChatGPT, Work And Codex Integration
Another possible focus is deeper integration between ChatGPT, Work and Codex. OpenAI has already been expanding the role of Codex and Work, while GPT-6 Sol and Luna have been introduced to these environments.
A more connected ecosystem could allow developers and professionals to move more easily between conversation, software development, research and agentic workflows.
7. New Developer Tools And API Capabilities
At DevDay, the developer audience remains at the heart of the event. OpenAI's official programme is all about technical sessions for APIs and tools and hands-on demonstrations and workshops.
That makes new API features, developer tools, agent capabilities and workflow demonstrations among the most relevant areas to watch. Some of the biggest announcements may be aimed less at everyday ChatGPT users and more at developers building applications on OpenAI's platform.
OpenAI DevDay Exchange Coming To Bengaluru
Indian developers will also have a local opportunity to engage with OpenAI after the San Francisco event. OpenAI has scheduled DevDay Exchange Bengaluru for October 16, 2026.
DevDay Exchange events will include technical sessions with OpenAI product and engineering teams, real-world projects and Codex workflows, hands-on guidance and discussions with developers and OpenAI teams, OpenAI said. Bengaluru is one of several cities hosting the programme, along with Tokyo, Seoul, Berlin, Paris, London, São Paulo and Mexico City.
The Bengaluru event is scheduled to begin at 2 PM local time, with venue and full programme details to be shared following application approval.
What To Expect From OpenAI DevDay 2026
With GPT-6 Sol and Luna already introduced, the focus in DevDay 2026 will be on how OpenAI's latest models are being integrated into practical developer workflows. AI agents, faster inference, coding tools, APIs and the wider ChatGPT ecosystem will be key topics.
But a few of the more specific product rumours that are circulating online are not verified. Until OpenAI makes an official announcement, any news about a new subscription tier, always-on assistant or specific ChatGPT interface changes should be treated as speculation.
The key date for Indian AI enthusiasts and developers is September 29. The keynote starts at 10:30 PM IST and will allow viewers in India to follow OpenAI's announcements as they happen.
