Sam Altman, the mind behind OpenAI, recently gathered the tech world in San Francisco. At the company’s DevDay 2025 event, he shared some eye-popping numbers. ChatGPT, their popular AI assistant, now boasts over 800 million active users every single week. That’s a huge leap, showing a 60% jump in just half a year.
This surge makes ChatGPT a dominant force in artificial intelligence. Altman told thousands of attendees that the system handles over 8 billion "tokens" per minute through its main interface. He also noted that more than 4 million developers are building apps and solutions using OpenAI’s AI platform, according to Cryptopolitan. The event itself, streamed on YouTube, drew over 114,000 viewers in its first hour, highlighting global interest.
ChatGPT’s Remarkable Ascent
ChatGPT launched a little over two and a half years ago. Its rise has been incredibly fast. In March 2025, OpenAI reported 500 million weekly users. By August, that number was nearing 700 million. Now, hitting 800 million users solidifies its leading spot in generative AI.
Altman pointed out a big shift. He said AI moved from "something people experiment with" to "a tool they build with every day." This cultural change comes from ChatGPT fitting into daily work, school, and new software projects.
New Partnerships and Tech Boosts
During the conference, OpenAI announced a major deal with AMD. This partnership means OpenAI will deploy 6 gigawatts of AMD Instinct GPUs by 2025. The agreement also gives OpenAI the chance to buy up to 10% of AMD’s shares.
Altman shared his excitement on X, saying, "Excited to partner with AMD to use their chips and serve our users. The world needs much more compute." This move strengthens OpenAI’s tech backbone. It helps them scale their AI services in the cloud.

Expanding the Ecosystem with New Products
OpenAI used DevDay to introduce three new products, with more details found on their official blog:
Apps SDK: This tool lets users interact with other applications directly inside ChatGPT. Think big names like Spotify, Canva, Coursera, Figma, Booking.com, Expedia, and Zillow.
AgentKit: This is a set of tools for businesses and developers. It helps them create their own custom, self-operating AI agents.
Codex: This is an expanded version of their code-generating AI model. It makes programming with natural language even more powerful and is now widely available.
The company also shared updates on Sora. This AI-powered video application now includes a built-in social network.
OpenAI’s Future and the AI Race
OpenAI is still legally controlled by a non-profit organization. However, its market value is massive. It stands as the world’s most valuable private company, worth USD $500 billion. This follows a recent share sale of USD $6.6 billion.
With its rapid growth and continuous product launches, OpenAI strengthens its lead. It competes against major players like Anthropic, Google DeepMind, and xAI. ChatGPT’s success also signals a new era for AI worldwide. Natural language tools are becoming a bigger part of daily life, from learning in schools to buying things online.
