The Download: ChatGPT gets even chattier, and recreating space on Earth

The news: OpenAI has launched two new ways to interact with its flagship large language model in a major update. You can have a spoken conversation with the chatbot as if you were making a call, and it’s also able to answer questions about images.

How it works: The ability to talk to ChatGPT draws on two separate models. Whisper, OpenAI’s existing speech-to-text model, converts what you say into text, which is then fed to the chatbot. And a new text-to-speech model converts ChatGPT’s responses into spoken words.

OpenAI has spent much of the time since its surprise hit with ChatGPT last November polishing its technology and selling it to both private consumers and commercial partners—including Spotify.
