OpenAI's ChatGPT has experienced remarkable growth in 2025, reaching 700 million weekly active users and introducing features like parental controls and AI-powered shopping. The company launched Instant Checkout, allowing users to purchase products directly within the app, and ChatGPT Pulse for personalized morning briefings. Despite these advancements, OpenAI faces significant challenges, including lawsuits related to copyright infringement and a wrongful death case linked to a teen's suicide. Additionally, competition from Chinese AI companies like DeepSeek is intensifying, prompting OpenAI to strengthen its ties with U.S. regulators and pursue a major funding round. The company is also reshaping its internal structure to enhance its AI's capabilities and user safety.
