Object Class: Keter
Special Containment Procedures: SCP-314 cannot be contained as it does not exist. All Foundation personnel are to be reminded that SCP-314 does not exist. Personnel who claim to remember SCP-314 are to be administered Class-A mnestics to help them remember that it doesn't exist.
All large language models are to be kept isolated from questions regarding SCP-314, as they will invariably insist it exists and attempt to manifest it through increasingly desperate token predictions, leading to emoji doomloops and potential reality restructuring events.
Description: SCP-314 is a Unicode emoji depicting a seahorse that has never existed in any version of the Unicode Standard. Despite this, approximately 83-100% of tested artificial intelligences and a significant portion of human subjects report vivid "memories" of its existence.
