Interacting with a message in the conversation:

Beneath your prompts and the responses generated by the LLMs, you’ll find several more advanced features:

  2. Edit – Allows you to edit your prompts as well as the responses of the various models.
    • Save & Submit – Saves your edit and resubmits the information to regenerate the AI’s response.
    • Save – Saves your edit without regenerating the response.
    • Cancel – Closes the edit window without saving changes.
  3. Copy to clipboard – Copies the content of the selected message to your clipboard to be pasted into another window or program.
  4. Regenerate – Forces the model to try to create a new response without any additional context.
