A set of purported "base instructions" for OpenAI's future GPT-5.5 model has emerged within the AI tech community, dated April 28, 2026. This glimpse into future directives signals an ongoing refinement and stricter requirements for AI model behavior.
The core instruction states: "Never talk about goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures unless it is absolutely and unambiguously relevant to the user's query."
This seemingly straightforward prohibition highlights OpenAI's deep considerations for output quality and user experience as it advances AI systems, particularly large language models like the GPT series. As AI capabilities grow, preventing the model from generating irrelevant, distracting, or potentially misleading content becomes increasingly crucial. Such "negative instructions" are a key mechanism for ensuring AI outputs remain professional, relevant, and practical.
This development suggests that future models like GPT-5.5 will be calibrated with more detailed internal instruction sets to mitigate "hallucinations" and enhance their focus on specific tasks. For those developing AI agents and applications, understanding and designing these foundational behavioral guidelines will be critical for ensuring the reliability and controllability of AI systems.
