This article outlines how the Sora Android app was developed in just 28 days using Codex. It discusses the challenges and advantages of integrating Codex into the engineering workflow, emphasizing the importance of clear guidance and context for effective collaboration.

The Codex app transforms how developers interact with AI agents, enabling them to manage multiple tasks and collaborate effectively. It offers new skills that extend beyond code generation, allowing Codex to perform a variety of tasks on a computer. Developers can customize their interactions with Codex, choosing between a direct or conversational style.

OpenAI has launched Codex, a coding tool designed for developers to delegate simple programming tasks to an AI agent that generates production-ready code. Accessible via the ChatGPT web app, Codex operates within a user’s development environment and can be customized through an “AGENTS.md” file for improved effectiveness. Built on a fine-tuned model, Codex leverages reinforcement learning to enhance its coding capabilities.
