ChatGPT, OpenAI’s text-generating AI chatbot, has taken the world by storm since its launch in November 2022. What began as a productivity tool for writing essays and code has grown into a platform with 300 million weekly active users. In 2025, OpenAI faced challenges, including competition from Chinese rivals like DeepSeek and the need to strengthen its relationship with the U.S. government. The company also pursued ambitious data center projects and prepared for one of the largest funding rounds in history.

As the year unfolded, headlines about OpenAI frequently centered on its competition, particularly following CEO Sam Altman’s internal memo that declared a “code red,” signaling a renewed focus on improving its flagship chatbot amidst rising competition.

The developments of 2025 followed a packed 2024, which included OpenAI’s partnership with Apple for its generative AI offering, the release of GPT-4o with voice capabilities, and the much-anticipated launch of its text-to-video model, Sora. OpenAI also dealt with internal challenges, including the exits of significant executives like co-founder Ilya Sutskever and CTO Mira Murati, as well as legal issues stemming from copyright infringement lawsuits.
