OpenAI Codex Now Uses Your Computer: The AI Operating System Era Has Begun
OpenAI has transformed Codex into a "super app" with a massive update. Codex is no longer just a coding tool — it is an autonomous AI assistant that can open apps on your Mac with its own cursor, click, edit your files, and learn your work habits. The platform, used by 3+ million developers weekly, is poised to fundamentally change how we use computers with 90+ new plugins, parallel agent support, and a memory feature.
1. Computer Use: AI Navigating with Its Own Cursor
With the update published on April 16, 2026, Codex can now operate on your Mac using its own cursor. Clicking, typing, app switching — all performed in the background without interrupting the user's work. Multiple agents can work in parallel while the user continues their own tasks.
This feature is proof that AI has transcended the "chat window" limitations and evolved into an autonomous work partner that takes action in the real world. According to gHacks' report, Codex is no longer a "command-line assistant" but a "digital coworker."
According to Gartner's April 2026 data, enterprise adoption of AI agents with computer use capabilities will increase 400% by the end of 2027. OpenAI is strengthening its position with this early move.
2. Memory: AI That Knows You
Codex's new Memory feature learns user preferences, past corrections, and work patterns. According to MacRumors' report, the system becomes more personal and efficient over time — understanding a little better with each interaction.
This can be thought of as the developer version of Google's Personal Intelligence announced in March. But the difference is significant: Google analyzes your data, Codex learns and repeats your actions.
According to McKinsey's 2026 report, developers using personalized AI assistants produce code 34% faster on average. The memory feature could push this rate even higher.
3. 90+ Plugins: All Your Workflows in One Place
The new update comes with 90+ plugins: Slack, Notion, Google Docs, GitHub, Jira, and more. Codex can now perform context switching between these applications and manage cross-platform workflows.
For example: it can summarize the latest meeting notes from Slack, update the project plan in Notion, and open a new issue on GitHub — all from a single command. According to VentureBeat's analysis, this approach directly competes with traditional workflow automation tools (Zapier, Make, etc.).
According to IDC's forecasts, the AI agent orchestration market will reach $28 billion by 2027. Codex's 90+ plugin integration makes it one of the most ambitious players in this market.
4. Parallel Agents: Multiple Tasks, Simultaneously
One of Codex's most striking features is the ability for multiple agents to work simultaneously. While one agent reviews your code, another can scan your emails, and a third can resolve your calendar conflicts.
According to OpenAI's blog post, Codex can even suggest how to start your day: it pulls relevant context from multiple apps and presents a prioritized action list. This is the most concrete example of AI's transition from "reactive assistant" to "proactive work partner."
According to Forrester's 2026 report, enterprise solutions using parallel agent architecture achieve 2.7x higher task completion rates compared to single-agent systems.
5. The AI Operating System Era: What Does It Mean?
The Codex update represents a critical threshold in AI evolution. In the past, AI was a "tool" — users asked, AI answered. Now AI uses your computer, navigates between your applications, and autonomously manages your workflows.
To understand the magnitude of this shift: last week we wrote about Anthropic restricting its Mythos model as "too dangerous." This week, OpenAI is giving AI full control of your computer. The industry is simultaneously accelerating and braking — this tension will be the defining characteristic of 2026.
TAO AI LAB Perspective
At TAO AI LAB, Codex's transformation directly validates our agentic workflows vision. The real value of autonomous workflowsis not being smart in a single application, but coordinating different systems to manage end-to-end business processes. Reasoning AI systems have now left the chat window and moved to your desktop — and this is just the beginning.
