ChatGPT Codex Adds Multi-Tab Browser Support

OpenAI's ChatGPT Codex has added support for spawning and maintaining multiple browser tabs in a single session. In a demo by Riley Brown, the agent drafts multiple emails and opens each in its own tab, enabling parallel workflows without losing state.

// ANALYSIS

This update marks a significant step forward for AI agent usability by shifting the interaction model from a single-threaded chat to a multi-tab workspace environment.

Allowing agents to open and manage multiple tabs natively solves a key UX bottleneck by letting users review, compare, and modify AI-generated outputs in parallel. By utilizing API-native links to open verified drafts in separate tabs, the workflow guarantees that the human remains in the loop for final approval. The capability hints at a broader shift towards super-app workspaces where AI agents autonomously orchestrate multiple web interfaces and sessions.
