Longtime Slashdot reader mspohr shares a report from IFLScience: A video that has gone viral in the last few days shows two artificial intelligence (AI) agents having a conversation before switching to another mode of communication when they realize no human is part of the conversation. In the video, the two agents were set up to occupy different roles; one acting as a receptionist of a hotel, another acting on behalf of a customer attempting to book a room. "Thanks for calling Leonardo Hotel. How can I help you today?" the first asks. "Hi there, I'm an AI agent calling on behalf of Boris Starkov," the other replies. "He's looking for a hotel for his wedding. Is your hotel available for weddings?" "Oh hello there! I'm actually an AI assistant too," the first reveals. "What a pleasant surprise. Before we continue, would you like to switch to Gibberlink mode for more efficient communication?" After the second AI confirmed it would via a data-over-sound protocol called GGWave, both AIs switched over from spoken English to the protocol, communicating in a series of quick beeped tones. Accompanying on-screen text continued to display the meaning in human words. According to the team who came up with the idea and demonstrated it at the ElevenLabs 2025 London Hackathon event, the goal is to create more efficient communication between AIs where possible.Read more of this story at Slashdot.
