Open AI has just revealed the latest version of the AI chatbot ChatGPT. It’s called GPT-4o and is faster, more friendly, and even flirtatious. Tech journalist Rhiannon Williams explains how it differs from previous versions, and what this means for the future of AI technology.

But not everyone has equal access to ChatGPT. Grace Kejo, a 17-year-old student in Tanzania, shares why. Plus, Maria Clara Montoya describes how AI voices have changed over time: from the 1950s speech recognition systems to Siri and Alexa, and the present day.
