Gibberlink

Gibberlink is a project, posted in GitHub, in which two conversational AI agents switch from speaking to one another in English to their own unique language that consists of a sound-level protocol after confirming they are both AI agents.

This project won the global top prize at the ElevenLabs Worldwide Hackathon.

[2] It has also been cited as highlighting concerns around AI, transparency, and the risks that this technology may carry.

[3] On February 23 2025, a Youtube video of two independent conversational ElevenLabs AI agents being prompted to chat about booking a hotel (one as a caller, one as a receptionist) received coverage for going viral.

In this video, both agents are prompted to switch to ggwave data-over-sound protocol when they identify the other side as AI, and keep speaking in English otherwise.
