OpenAI Codex in 7 Minutes: The Desktop App, Plan Modes, and Multi-Agent Workflows

Official Sources#

What This Video Covers#

OpenAI Codex in 7 Minutes showcases OpenAI's Codex desktop app. The video walks through plan and goal modes, plugins, multi-agent workflows, and a UI annotation demo, presenting the desktop app as OpenAI's strongest coding product to date.

This post is a companion to the video above. Watch the seven-minute tour for the live demos, then use the links here to place each feature in context.

The Idea in One Line#

Codex is moving from a single prompt-and-respond loop to a desktop app with modes, plugins, and multiple agents. The pitch is less "chat with a model" and more "run a coding environment where the agent has structure to work inside."

Why It Matters#

A few things stand out from the tour:

• Plan and goal modes add structure. Instead of one long instruction, you can point Codex at an outcome and let it plan the steps. This is the same direction covered in Codex goal mode versus Claude managed outcomes.
• Plugins extend what it can reach. A plugin surface means the app is meant to connect to your tools, not live in a sandbox by itself.
• Multi-agent workflows split the work. Running more than one agent lets you break a task into parallel pieces, which changes how large jobs get done.
• UI annotation closes the loop. Annotating the interface gives the agent a way to act on what is actually on screen.

Where It Fits#

The desktop app is one part of a fast-moving product. For the fundamentals, the OpenAI Codex guide covers the basics, and Codex Record & Replay shows another recent feature that turns recorded tasks into reusable skills. If you want recurring work handled automatically, Codex automations for recurring engineering work is the next stop. Weighing tools? Codex vs Claude Code (June 2026) compares them directly.

Getting Started#

The workflow the video demonstrates is to open the desktop app, pick plan or goal mode for a real task, and let the agent work while you review. Start small so you can see how the modes and plugins behave before handing over anything large.

Watch the full OpenAI Codex in 7 Minutes tour above, then try plan mode on a task of your own and see how the desktop app changes your loop.

FAQ#

What is the difference between plan mode and goal mode in Codex?#

Plan mode has the agent lay out steps for a task before executing them, while goal mode points Codex at an outcome and lets it plan the steps itself. See Codex goal mode versus Claude managed outcomes for a practical comparison of the two approaches.

Does the Codex desktop app support multiple agents at once?#

Yes. The desktop app supports multi-agent workflows that split a task into parallel pieces, which changes how larger jobs get handled compared to a single prompt-and-respond loop.

How does Codex compare to Claude Code?#

Where should I start if I am new to Codex?#
