OpenAI raised the stakes again at its 2025 DevDay, unveiling updates that signal a shift in how AI integrates into daily life and business operations. With 800 million weekly users and new developer tools, the company is moving from AI provider to platform builder. As highlighted in a detailed recap by Wezley Kibz, these announcements show an AI ecosystem evolving faster than many anticipated.
Key Announcements
ChatGPT now serves 800 million weekly active users, processing 6 billion tokens per minute. OpenAI expects to hit 1 billion users by the end of 2025, reflecting the rapid adoption of generative AI across sectors.
The Apps SDK launch enables developers to build applications that run directly inside ChatGPT. Early partners like Canva, Zillow, Coursera, and Figma demonstrate the platform's versatility. An upcoming App Store with monetization will create new opportunities for AI-focused developers.
AgentKit provides tools for creating AI agents without extensive coding. It includes a drag-and-drop Agent Builder, ChatKit for conversational interfaces, Evals for testing, and Connectors for live data integration. Businesses can now deploy agents for customer support, research, and workflow automation more easily.
The developer-focused GPT-5 Codex is now available to everyone, featuring Slack integration for real-time assistance and a new SDK with enterprise analytics. API updates include GPT-5 Pro at $15 input and $120 output per million tokens for large-scale operations, GPT-Realtime-Mini optimized for live voice at 70% lower cost, and Sora 2 with enhanced audio and remixing capabilities.
What It Means
OpenAI is building an ecosystem inside ChatGPT that resembles early smartphone app stores. The Apps SDK and AgentKit give enterprises and developers tools to create, deploy, and monetize AI-native applications directly within the platform.
If adoption continues at this pace, OpenAI's approach could reshape how people interact with technology, much like mobile platforms did a decade ago. The question now is whether the ChatGPT ecosystem will grow as explosively as its predecessors.
