Introducing GPT-4o
OpenAI. This is the live 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.

Coursera · DeepLearning.AIGenerative AI for Everyone
Real time inside an LLM, learning to prompt deliberately and recognise where generative AI is genuinely useful versus where it's a trap. Calm, no-hype teaching — the perfect bridge from "I've tried ChatGPT once" to "I use it every day with confidence."
Coursera · DeepLearning.AI + AWSGenerative AI with Large Language Models
When practitioners ask "what should I take if I'm serious about building with LLMs?", this is the answer. Mathematically honest without being a research paper; AWS-flavoured deployment chapters stay useful even if you'll never touch SageMaker.
Anthropic AcademyMCP: Build Rich-Context AI Apps with Anthropic
MCP is the protocol that's quietly replacing one-off tool integrations across the AI tooling ecosystem. Learn it from the source. By the end you'll have built and deployed your own MCP server, connected an LLM client to it, and understood why this standard is the closest thing the field has to USB-C.
