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.
