Assessment
This is a supercut of OpenAI's official DevDay 2026 keynote, featuring executive presentations by Sam Altman and multiple live on-stage demonstrations. The live demos showcase functional prototypes, software interfaces (ChatGPT Space, Codex CLI, Slack integration), and real-time physical interaction with an external programmable robot toy.
