After the update, the desktop version of Codex will become the brand-new ChatGPT desktop application, including three components: Chat, ChatGPT Work, and Codex. After the update, the application will retain existing Codex tasks and projects, and users can also choose the Codex application icon in settings. The previous ChatGPT application becomes the ChatGPT Classic application.
At the same time, OpenAI is preparing to further simplify its product structure: in the coming weeks, it will open testing of the merger of Chat and Work to a small group of users. After the merger, users will be able to complete the process from proposing ideas to having ChatGPT execute tasks within the same interface, for example importing files or plugins, having it build websites, generate presentations, or complete operations on web pages, and review and guide its work at any time. Codex will still remain in the ChatGPT desktop application as a standalone experience.
Regarding entitlements, OpenAI plans to merge the usage quotas of ChatGPT and Codex into a shared quota, replacing the current limits that are calculated independently. The company said most users will not wait for quota resets more frequently than they do now; actual consumption will depend on the model used and task complexity, with advanced models and complex tasks consuming more quota, while "unlimited instant" usage within the plan will not consume the shared quota.
