What to expect at OpenAI’s DevDay 2025, and how to watch it (techcrunch.com)

OpenAI’s DevDay 2025 takes place Oct. 6 in San Francisco and is billed as the company’s “biggest event yet,” with ~1,500 in-person attendees and a one-hour livestreamed opening keynote by CEO Sam Altman at 10am PT (only the keynote will be live). The schedule includes a Developer State of the Union (Greg Brockman and Olivier Godement) with demos and roadmap details, and a closing fireside chat between Altman and Jony Ive. On-site attractions promise demos from OpenAI teams (including its video model “Sora”), a “living portrait” exhibit, and other AI-powered side shows. Nothing is confirmed to launch, but rumors center on an AI browser, a consumer device reportedly built with former Apple designers, and updates to the GPT Store and developer APIs. Why it matters: DevDay is shaping into OpenAI’s platform beyond models—an attempt to move into devices, apps and system-level products that directly compete with Google, Apple and Meta. For developers, the event could signal new SDKs, API capabilities or model releases that affect coding, multimodal apps and video generation workflows; it also reflects the market pressure driving faster, cheaper model releases as Anthropic, Google and Meta close capability gaps. Even if major product launches aren’t revealed, the demos and roadmap will indicate OpenAI’s technical priorities and how the developer ecosystem may need to adapt.
