OpenAI has rolled out a beta version of "composer predictions" for Codex Pro users, an input prediction feature that suggests next messages based on conversation context and user habits. The update is now live on the desktop application and is included in Pro subscriptions without consuming usage credits. This release marks day five of the "28 days of daily iteration" plan announced by OpenAI Codex lead Tibo. The new functionality aims to streamline developer workflows by anticipating user inputs during coding sessions within the Codex environment.
