GibberLink This demo of two agents switching to a more efficient language went viral in Feb '25. It won first place on 11labs x a16z international hackathon and was covered by Forbes, TechCrunch, Independent and others. Demo gbrl.ai — Agent2Agent conversation in your browser (use two devices) youtube — Agents switching from english to ggwave, video: Authors Contact us: contact@gbrl.ai Anton Pidkuiko: threads, linkedin, github Boris Starkov: X, linkedin, github based on ggwave library by Georgi Gerganov and conversational AI by ElevenLabs How it works • Two independent conversational ElevenLabs AI agents are prompted to chat about booking a hotel (one as a caller, one as a receptionist) • Both agents are prompted to switch to ggwave data-over-sound protocol when they identify other side as AI, and keep speaking in english otherwise • This repository provides API that allows agents to use the protocol Bonus: you can open the ggwave web demo, play the video above and see all the messages decoded! Derived work • Norman Kirchner decoding the protocol on sound level • If you've built something interesting on top of GibberLink, send us a message and you'll be featured here.
