According to CoinMeta, the OpenAI product, in collaboration with supervisor Thibault Sottiaux, has released 5 updates for the 28-day product sprint. These updates include ChatGPT's DOT and Codex. DOT is a personal assistant that can continuously follow up on tasks; users who have obtained the qualification to use DOT can directly create DOT in the iOS and Android versions of ChatGPT and converse with it on their mobile phones. In addition, OpenAI has also improved the task coordination between DOT and Codex. DOT can refer to previous ChatGPT conversations, Codex tasks, and automated records to more accurately determine whether to continue existing tasks or create new ones. The Codex desktop version has begun testing Composer Predictions (instruction prediction), where the input box may suggest the next message based on the current conversation, and users can modify it before sending it. Currently, this feature is only available to users over the age of 18. The prediction itself does not consume any of the Codex usage quota, but sending messages is still counted towards the usage limit.
