Technical Definition
Knowledge cutoff is the date after which an LLM has no training data. Events after the cutoff aren't in the model's knowledge without web search. Different models have different cutoffs. When web search is enabled, LLMs can access current information. Understanding cutoffs helps explain why some AI responses are outdated.
Simple Explanation (ELI13)
Knowledge cutoff is the date when an AI stopped learning from the internet. If ChatGPT's cutoff is April 2024, it doesn't 'know' about anything that happened after that unless it searches the web. This is why AI sometimes gives outdated answers about recent events.
