Since its debut in November 2022, ChatGPT, OpenAI's text-generating AI chatbot, has captivated users worldwide, resulting in an impressive 300 million weekly active users by 2025. As OpenAI navigated a competitive landscape, it faced challenges from rivals, particularly in the context of perception concerning its standing against Chinese companies like DeepSeek. The year was marked by strategic partnerships, substantial funding efforts, and heightened competition that prompted a significant pivot in focus, particularly highlighted by an internal memo from CEO Sam Altman.

The developments in 2025 followed a dynamic 2024, which included a partnership with Apple for its generative AI offering, the introduction of GPT-4o with voice capabilities, and the much-anticipated launch of the text-to-video model Sora. However, internal upheaval also characterized the company, with the departure of high-profile executives such as co-founder Ilya Sutskever and CTO Mira Murati. Furthermore, OpenAI faced legal challenges, including lawsuits regarding copyright infringement and an injunction from Elon Musk regarding its transition to a for-profit model.
