Knowledge Cutoff

Knowledge cutoff is the date after which a model’s training data no longer includes real-world information. Events beyond that date are unknown unless retrieved through external tools. For prompt engineers and product teams, awareness of the knowledge cutoff guides how much to rely on the model’s built-in knowledge versus retrieval, especially for time-sensitive Ai Messages and search-related tasks. Knowledge cutoff is the date after which events and information are not captured in a model’s training data. The model may not know about developments beyond that point unless connected to external tools. For prompt engineers and product teams, understanding the knowledge cutoff guides when to rely on retrieval or human review for time-sensitive topics.
