OpenAI DevDay Exchange, London 2026

OpenAI DevDay Exchange London is an independent keynote-design study exploring how OpenAI’s developer story could be translated into a focused, stage-led experience for a London audience. The narrative follows a clear architectural progression: GPT-Live creates the interaction layer; GPT-5.6 provides scalable intelligence for reasoning, tool use and complex work; and OpenAI Presence provides the production controls required to deploy and operate dependable agents. The story moves from natural, continuous conversation, through deeper work happening behind the interaction, to the policies, permissions, evaluations and human oversight needed in production. Designed for developers, technical founders, researchers and product leaders, the presentation combines stage-scale typography, restrained gradients, interaction timelines and fully editable system diagrams. Each chapter has a distinct visual character: fluid blue fields for live interaction, electric violet for scalable intelligence, and high-contrast operational diagrams for production control. Illustrative scenarios are clearly identified, product claims are grounded in official OpenAI material, and every composition is designed for rapid comprehension at venue scale.
