How to Use Codex on Your Computer? A Deep Dive into Three Operational Interfaces and Permission Boundaries
OpenAI's Codex isn't just about one way to "use your computer". Depending on the task scenario and permission needs, Codex provides three different interfaces: Computer Use (desktop-level operations), Chrome Extension (browser multi-tab operations), and In-App Browser (development debugging).
• Computer Use: This has the broadest coverage, allowing direct manipulation of native applications on macOS/Windows, system settings, iOS simulators, etc. It's suitable for GUI processes without API support, but it's slower and has the widest permission boundary.
• Chrome Extension: This leverages the logged-in state of the browser to handle multi-tab tasks for Gmail, LinkedIn, Salesforce, etc., which require authentication. It carries the user's identity, making it more powerful but also more sensitive.
• In-App Browser: This has the strongest isolation, not inheriting the user's browser configuration, making it ideal for local development, visual bug reproduction, and responsive layout debugging.
Core Principle: If plugins or MCP can be used, avoid visual control; prioritize In-App Browser for web development tasks; switch to Chrome when user browser identity is needed; and only use Computer Use as a last resort when structured tools cannot cover the task.
Why It Matters: The key to AI Agent productization isn't about giving the model unlimited permissions, but rather continually narrowing those permissions and clarifying boundaries for specific tasks, while allowing users to retain review rights over critical actions. This layered design represents a significant milestone in the evolution of AI programming tools from "command line assistants" to "full-stack operating systems".
