Since its launch in November 2022, ChatGPT, OpenAI’s text-generating AI chatbot, has rapidly grown in popularity, boasting 300 million weekly active users. In 2025, OpenAI navigated intense competition, particularly from Chinese rivals like DeepSeek, while striving to strengthen ties with U.S. policymakers and prepare for a historic funding round.
Throughout 2024, OpenAI had solidified its position by partnering with Apple and releasing advanced models like GPT-4o with voice capabilities and the anticipated text-to-video model, Sora. However, internal upheaval marked the year, highlighted by the exits of key figures such as co-founder Ilya Sutskever and CTO Mira Murati, alongside ongoing legal battles over copyright and an injunction from Elon Musk against its profit transition.
