Since its launch in November 2022, OpenAI’s ChatGPT has taken the world by storm, evolving from a simple AI tool into a powerhouse with a staggering 300 million weekly active users by 2025. As OpenAI faced stiff competition from rivals, particularly in the AI sector, the company focused its efforts on enhancing its flagship chatbot, especially following an internal memo from CEO Sam Altman that emphasized the urgency of addressing competition.
In 2025, OpenAI's trajectory included significant partnerships, including one with Apple for their generative AI offering, Apple Intelligence, as well as the release of the innovative GPT-4o model featuring voice capabilities and the anticipated launch of the text-to-video model Sora. However, 2025 was also marred by internal turmoil, with the departures of key executives and legal challenges, including copyright infringement lawsuits.
