OpenAI used its OpenDev stage on October 6, 2025 to push ChatGPT from a capable assistant into a platform you can build on. The headliners were apps that run directly inside ChatGPT via a new Apps SDK, AgentKit for building and shipping agentic workflows, general availability of Codex with a fresh SDK and Slack integration, and a strategic AMD partnership aimed at scaling compute to six gigawatts. This post breaks down what shipped, why it matters, and how developers can start building today.

Model Context Protocol Servers and AI… What???
Model Context Protocol (MCP) servers are reshaping how AI systems interact with the world. Think of them as standardized “ports” that let AI tools securely and intelligently plug into other systems, whether it’s file storage, databases, productivity tools, or developer environments. As the AI ecosystem matures, these servers are becoming critical infrastructure, quietly powering some of the most advanced capabilities in tools like Claude, Copilot, and Replit’s Ghostwriter.
This post digs into the Model Context Protocol (MCP), how servers implement it, why it’s becoming the USB‑C of AI, and what it means for developers building the next generation of intelligent apps.
