OpenAI CEO Sam Altman has announced a significant milestone: ChatGPT now boasts over 800 million weekly active users. This remarkable growth highlights the widespread adoption of the AI platform across consumers, developers, enterprises, and governments worldwide.

### Rapid Growth and Adoption

In just a few months, the platform has seen explosive growth. By the end of March, ChatGPT had reached 500 million weekly active users, and by August, it was nearing 700 million. The latest figures show continued acceleration as OpenAI ramps up efforts to acquire AI chips and build the necessary infrastructure to support increased demand.

### Developer Engagement and API Usage

Altman emphasized the strong developer involvement in the OpenAI ecosystem. Currently, over 4 million developers have built applications using OpenAI’s technology. He shared, “More than 800 million people use ChatGPT every week, and we process over 6 billion tokens per minute on the API.”

This surge in developer activity marks a shift in AI’s role—from being a novelty or toy to becoming an essential tool integrated into everyday workflows and applications.

### New Tools Unveiled at OpenAI Dev Day

The milestone announcement was made during the keynote presentation at OpenAI’s Dev Day event. The company introduced a suite of new app-building tools aimed at creating more interactive, adaptive, and personalized AI applications. Altman noted, “This will enable a new generation of apps that are interactive, adaptive, and personalized,” signaling a move toward more sophisticated, agentic AI systems within ChatGPT.

### OpenAI’s Market Position and Recent Innovations

Despite its initial nonprofit status, OpenAI has emerged as the world’s most valuable privately held company following a $6.6 billion private stock sale that valued it at $500 billion. The company continues to expand AI’s reach with new features designed to enhance creativity and utility.

Among the latest launches:

– **ChatGPT Pulse:** Personalized daily briefings available for Pro users.
– **Shopping Integrations:** Partnerships with Etsy and Shopify allow users to make purchases seamlessly within chat.
– **Sora 2:** A tool delivering highly realistic AI-generated videos with synced audio.
– **Sora Social App:** A platform where users can share and explore AI-generated video creations.

These innovations demonstrate OpenAI’s commitment to pushing the boundaries of AI technology, making it more accessible and useful across various domains.
