Sam Altman's OpenAI is reportedly testing a new social media application to challenge Elon Musk's X, formerly known as Twitter. This move signifies a significant escalation in the ongoing technological rivalry between OpenAI and Musk. The introduction of a competitor to X indicates OpenAI's ambition to expand its influence in the social media landscape.

The competition between Altman and Musk could drive innovation in the social media sector as OpenAI aims to leverage its expertise in artificial intelligence. This development marks a new phase in the longstanding rivalry between these two industry leaders.
