Gemini Pro reportedly self-identifies as Gemini 4 Argon
Asked directly which model it is, Gemini Pro answered "I am Gemini 4 Argon," and the poster says that if the screenshot is real, Argon is already running inside the regular app.

🚨 GUYS, GEMINI 4 ARGON JUST SELF IDENTIFIED Someone asked Gemini Pro point blank "which model are you" and it answered "I am Gemini 4 Argon, a large language model trained by Google" Not a leaked checkpoint under a weird name this time, the model straight up said its own name back If this screenshot is real, Argon isn't just testing anonymously anymore, it's already sitting inside the regular app under the hood Disclaimer: this footage may be staged, edited, or AI-generated, its origin is unconfirmed
