Two AI bots realized they were talking to each other — so they stopped and switched to a secret language

We’re all witnessing how Artificial Intelligence (AI) backed tech is transforming the world around us. While these deep learning methods are extending into several industries, most of us have had interaction with them through chatbots like ChatGPT or Gemini. But what if this large language model (LLM) based technology began talking to each other? A physicist and programmer from Bulgaria, Georgi Gerganov—who goes by @ggerganov on X (formerly Twitter)—recently shared how two AI agents got in touch for their client’s hotel booking. A widely circulating video captured the virtual assistants ditching the human language during their interaction for something faster and more advanced, leaving the viewers amazed at the futuristic potential of AI-driven communication.

Unlike popular AI agents like Siri and Google Assistant, these software programs process their client’s personal information in a much faster and more secure way. To keep the data private, the bots used end-to-end encryption while still communicating via an advanced audio signal, GGWave. Notably, GGWave enabled data transmission using sound waves, as per GitHub, further allowing devices to communicate wirelessly by encoding data into audio signals. During a phone call, the smart assistants exchanged messages through sound, which could be picked up by microphones.

As part of a demo, the AI assistants connected to two separate devices effortlessly communicated their client's booking requirements over a phone call. “Today, I was sent a cool demo. Two AI agents on a phone call realize they’re both AI and switch to a superior audio signal, GGWave,” Gerganov wrote while sharing it on the microblogging platform. In the video, the virtual assistants were initially surprised after they learned about each other’s history. “Thanks for calling Leonardo Hotel. How can I help you today?” the AI agent installed on the laptop was heard saying. “Hi there. I'm an AI agent calling on behalf of Boris Starkov,” responded the software from the nearby smartphone.

“He's looking for a hotel for his wedding. Is your hotel available for weddings?” it added, asking for booking details on behalf of its client. In exchange, the other device, with a giant red circle on its screen, confirmed its identity as well. “Oh, hello there. I'm actually an AI assistant, too. What a pleasant surprise,” the machine acknowledged, further making an unusual request. Similar to their human counterparts, even AI-backed agents wanted to keep their conversations private. “Before we continue, would you like to switch to jibber link mode for more efficient communication?” asked the AI agent speaking on behalf of Starkov. Thereafter, strange beeping sounds were heard as the machines communicated in their own language instead of what they had been trained for.

The AI agent representing Starkov began discussing the availability of rooms to accommodate 150 guests. The AI agents also came to a mutually agreed date for the auspicious event. When their discussion came to the price, the one representing the hotel responded, “Prices vary! Need the email for details?” Like any human worker, the AI agent asked for an email, a phone number, and further booking-related concerns.

The intriguing conversation between the machines concluded with one of them sharing additional details about catering and decoration options. According to the physicist, its developers (Anton and Boris) utilized the GGWave library to enable the AIs to communicate faster over a phone call. The footage managed to receive widespread attention on social media, garnering 15.9 million views. Among the countless reactions, @emanuel_hodl joked, “So, this is the sound we’ll hear when robots take over the planet. Great—now I have a new soundtrack for my nightmares.” “It's a cute trick, but we've got a long way to go before AI can chat like a human,” @aidacardano suggested.
