Elon Musks firm had previously accused the Cupertino-based tech giant of giving special favor to ChatGPT in its App Store listings and editorial features.

The complaint filed in federal court in Texas contends the companies' partnership is designed to ensure "their continued dominance" in artificial intelligence.

Elon Musk accused Apple and OpenAI of "thwarting competition and innovation in the generative AI chatbot market" more than a year after the two companies partnered to integrate ChatGPT into Iphone operating systems, according to a lawsuit filed in the U.S. District Court for the Northern District of Texas.
