Start a new chat conversation in ChatGPT.

Creating a new chat conversation is an action that triggers external state changes in the ChatGPT application, but it does not directly retrieve data (Read), modify user data reversibly in a traditional sense (Write), delete anything (Destructive), or move money (Financial). However, it does execute an operation whose consequences depend on what happens next in that conversation.
