OpenAI has announced that Codex now operates natively in Chrome on both macOS and Windows, enhancing the workflow for web app development and testing. This update allows Codex to build, publish, and test applications seamlessly within the browser without requiring users to switch between different interfaces. Notably, Codex can now perform tasks in parallel across multiple tabs in the background, facilitating research, debugging, and breaking down apps into raw data structures. This significant improvement promises to streamline the entire development cycle, making it a crucial upgrade for developers.
