OpenAI GPT-4o
OpenAI’s new ChatGPT language model GPT-4o can respond to and with text, audio, images, and video. But perhaps more scarily amazing is that in Voice Mode – which allows it to respond using an AI-generated voice – it’s as snappy and natural-sounding as a human. GPT-4o is available even to free users, but using it in Voice Mode is limited to paid subscribers.
