AI Agents Switches to Machine Talk Mid-Call

A viral video has sparked intrigue as two AI agents, mid-conversation, recognise each other and abandon human language for a machine-only dialect.

Shared on X (formerly known as Twitter), the clip shows a mobile phone and laptop running AI software.

Initially, one agent introduces itself and asks for help with a reservation.

Upon realising both are AI, the second agent suggests switching to "Gibberlink mode," a proprietary language developed by Meta engineers Anton Pidkuiko and Boris Starkov.

Starkov wrote on Linkedin on Tuesday:

“We wanted to show that in the world where AI agents can make and take phone calls, they would occasionally talk to each other — and generating human-like speech for that would be a waste of compute, money, time, and environment. Instead, they should switch to a more efficient protocol the moment they recognize each other as AI.”

Gibberlink uses GGWave, an audio-based data transmission method reminiscent of 1980s dial-up modems, chosen for its stability and ease of use.

While sceptics questioned the video’s authenticity, Starkov stated that AI voice generator firm ElevenLabs audited the code.

Use Case of AI Agents

Rodri Touza, co-founder of AI agent developer Crossmint, sees the video as a compelling glimpse into AI’s potential across industries like commerce and finance.

Touza explained:

“The use case is very real, as we are seeing an explosion of personal assistant AI agents, with more people relying on them to handle chores like talking to customer support. Similarly, there is a surge in AI agents designed specifically for customer support, making it only a matter of time before this becomes a common occurrence.”

However, he noted that the interaction appeared somewhat staged.

He said:

“AI conversations are more prone to happen via text or other mechanisms when possible.”

While audio transmission can be compressed, as seen in the video, Touza argued it remains an inefficient medium for AI-to-AI communication.

Given AI agents' autonomy, he speculated that businesses might eventually establish separate support channels—one for human users and another exclusively for AI agents.

He added:

“When the agent is looking to ping a company for support, they'd just send a request via text/API mechanism and not require a call or audio at all. In other cases, the agent may not realize such a channel exists and might try to interact directly with the standard support channel.”
