Introducing GPT-4o

26 minutesNew to AIFoundationOpenAIChatGPT & LLMs

OpenAI. This is the May 2024 keynote where ChatGPT's real-time voice mode was first demoed. Mark Chen does the breathing-exercise demo, Barrett Zoph does the math-tutor demo, and then they switch to real-time Italian–English translation. Twenty-six minutes of "ah, that's what they mean by talking to AI like a friend." The model and capabilities shown have only improved since.

AI Expert note

This is historically useful, not a current capability spec. Before using voice in real customer or employee workflows, verify current consent, recording, retention, language, accessibility and escalation controls.

What you should get from this

Understand why real-time conversational voice feels different from dictation or classic voice assistants.

Watch or know first

None, but watch it as a launch demo rather than a current product manual.
