If you’ve recently updated your ChatGPT desktop app and noticed Codex seems to have vanished, don’t worry—it hasn’t disappeared. OpenAI has officially integrated Codex into the ChatGPT desktop interface, combining its development capabilities with the app’s existing features.
Previously, ChatGPT focused on conversational interactions while Codex handled coding tasks. Now, the app unifies three core functions: Chat for conversations, Work for productivity, and Codex for development—bringing chat, office, and coding tools into one seamless experience.
Key updates to note: Codex still supports local project operations; Work and Codex share the same agent quota; and GPT-5.6 introduces new task-specific models. For complex projects, use Sol; for daily development, Terra; and for simple tasks, Luna. Choosing the right model boosts efficiency and saves quota.
The new Codex is no longer just a code-writing tool—it’s evolving into a complete AI development workflow, offering end-to-end support for developers.
For those eager to master Codex, a 306-page manual is available, perfect for beginners. It covers zero-based tutorials (no prior coding knowledge needed), hands-on guides for configuration and automation, and a reference section with prompt templates and troubleshooting tips. This manual comes from Three Classes' OpenAI Codex Practical Course, which includes 17 chapters of practical, step-by-step content designed to help users apply their skills immediately.
