OpenAI Codex Upgraded to a Multi-Plugin, Multi-Terminal Agent Development Environment
Codex has recently added capabilities such as computer use, built-in browser, image generation and editing, over 90 plugins, multi-terminal support, SSH access to devbox, thread automation, and rich document editing. According to English materials, OpenAI has advanced Codex from a simple code assistant to a development agent capable of executing complex tasks across tools.
Previously, OpenAI positioned Codex as a coding system that can read and write files, run tests, and iterate continuously in isolated environments; it later added a plugin marketplace, MCP support, and a more complete remote workflow. The latest changes indicate that Codex is shifting from "writing code" to "taking tasks, running processes, and connecting systems" as a foundational productivity layer.

The real significance of this upgrade is that programming tools are transforming into universal work agents. The past code assistants only addressed localized writing issues, while the current Codex resembles an execution layer capable of interfacing with browsers, terminals, documents, and plugin systems, indicating a shift in software development focus from "inputting code" to "scheduling tasks."
This will reshape the division of labor within development organizations. Many actions that previously relied on human coordination, such as researching information, opening terminals, editing documents, running tests, creating image assets, and connecting third-party tools, are now being unified under a single agent system. The result is not merely increased efficiency, but enabling individual engineers to handle a more complete work cycle.
In the long term, this also marks a shift in the AI industry from model competition to workflow competition. Whoever controls the entry point of the development agent may control the entire chain from creativity to deployment, with future competition not only based on model capabilities but also on who can integrate models into real production processes.
