OpenAI Codex now features 'Agentic Computer Control,' allowing it to see, click, and type using its own virtual cursor. This is critical for interacting with applications that lack traditional APIs. Codex effectively 'sees' your desktop GUI and understands how to navigate and manipulate it, much like a human user would.

Furthermore, multiple agents can now run in parallel. This is invaluable for tasks requiring extensive parallel processing, such as:

• Comprehensive testing: Running different test scenarios simultaneously across various applications or environments.
• Frontend iteration: Testing multiple UI variations or browser compatibilities at once.
• Interacting with API-less apps: Orchestrating agents to work with older or proprietary software for which no direct programming interface exists.

Key Features: Scheduling, In-App Browsing, and Parallel Agents

The platform's new scheduling feature allows users to plan and execute tasks hours, days, or even weeks in advance. This is perfect for recurring administrative tasks, nightly builds, or long-running computations.

OpenAI Codex also includes an in-app web browser. This browser isn't just for general web surfing; it's a critical tool for:

• Reviewing Codex's output: Easily navigate to localhost or external web environments to see the results of Codex's work.
• Providing feedback: Users can leave specific comments on page elements within the in-app browser, allowing Codex to understand exactly what needs refinement.

For visual asset generation, the integration with gpt-image-1.5 is a game-changer. Developers and designers can now generate mockup images directly within the Codex environment, speeding up the prototyping and design iteration process.

Practical Steps to Utilize These Features:

1. Use the in-app browser to review Codex's output. After assigning a UI task, navigate to the relevant URL within the integrated browser to see the changes.
2. Leave specific feedback/comments on page elements. Click on an element within the in-app browser and provide direct instructions for Codex to refine it.
3. Schedule recurring or future tasks. Access the new task scheduler and set up automated administrative tasks, such as "Run database cleanup script every Sunday at 2 AM" or "Deploy staging build every Friday."

Under the hood, OpenAI Codex leverages "automation memory" to maintain context across complex, multi-step workflows. This ensures that even long-running, multi-agent tasks remain coherent and on track. The release in April 2026 marks a pivotal moment in developer productivity.
