A knowledge cutoff is a ceiling, not a snapshot

This article clarifies that a model's knowledge cutoff is a ceiling, not a snapshot of the world at that date. It explains that knowledge recency varies by topic, and even known versions may have gaps. For AI agent builders, this means extensions should target missing knowledge rather than repeating what the model already knows, to avoid wasting context and altering behavior.
