OpenAI's ChatGPT revolutionized the artificial intelligence industry with an intelligent bot that can chat with you. However, chatting with ChatGPT (as with most competitor models) doesn't feel like a real conversation; it's more of a Q&A session with a really knowledgeable nerd. On Wednesday, OpenAI launched GPT-Live, a new model that has a "full-duplex architecture," allowing it to listen and speak at the same time. This enables it to keep a far more realistic conversation, including giving you faster answers, and letting you know it's paying attention with an occasional "mhmm."
We haven't been able to test it out yet, though OpenAI posted a video showing the model's capabilities. The conversation does sound more natural, though the additional chatter probably takes some getting used to.

Google has a similar feature called Gemini Live, which can also keep up a longer conversation, though it doesn't seem to be as chatty as GPT-Live.
OpenAI says GPT-Live is the smartest voice model it has launched. Currently, it uses GPT-5.5 in the background, but the company says that will be "continuously updated" as new models are released. This is notable, as OpenAI is scheduled to launch its most powerful model yet, GPT-5.6, today.
