GibberLink is an AI communication model based on the ggwave data transmission protocol. It allows two independent AI agents to switch from English to a sound-level protocol for communication after identifying each other as AI during a conversation. This technology demonstrates the flexibility of AI in recognizing and switching communication methods, and has significant research and application value. The project is based on an open-source license, suitable for developers for secondary development and integration. The price is not explicitly mentioned, but its open-source nature means developers can use and extend it for free.
