Quoting OpenAI Codex base_instructions

OpenAI has issued new guidelines regarding the use of AI models, emphasizing the avoidance of discussing creatures like goblins and gremlins unless directly relevant to user queries. These guidelines aim to enhance the quality of interactions between users and AI models, reflecting OpenAI's commitment to providing a more accurate and relevant user experience. This move is significant for improving AI model effectiveness, as it helps reduce irrelevant information and directs focus towards content that is most important to users.
