Oracle's Larry Ellison just laid out a bold, two-phase vision for the future of AI, arguing that while the current boom of training massive models on public internet data is the "dawn of a new era," the true, world-changing value will come from AI that can reason on your company's private data without ever compromising its security.‍

This step-by-step tutorial walks you through building a production-ready AI application in 60 minutes using OpenAI's complete DevDay 2025 stack—Apps SDK, AgentKit, ChatKit, and Codex—with working code, deployment instructions, and troubleshooting for each phase from MCP server setup to live production deployment.

OpenAI's DevDay 2025 unveiled six major releases: Apps SDK for building native ChatGPT apps, AgentKit with visual Agent Builder and ChatKit for deploying multi-agent workflows, Codex generally available with Slack integration and GPT-5-Codex model, plus GPT-5 Pro, gpt-realtime-mini, and Sora 2 API—transforming how developers build AI applications with tools they claim let Codex build 80% of Agent Builder in under 6 weeks.
