OpenAI expands ChatGPT 'custom instructions' to free users

OpenAI's custom instructions feature that rolled out to ChatGPT Plus subscribers in July, is now available to all users. The addition of custom instructions puts a new setting in your ChatGPT profile on desktop or iOS, and applies that setting across all of your conversations. Instead of having to give ChatGPT certain instructions at the beginning of every new conversation, it automatically calibrates its responses based on descriptions you add in settings. Just fill out the fields in ChatGPT settings, and see how it adapts. The custom instructions section of settings contains two text entry fields.
