Knowledge Cutoff
A Knowledge Cutoff is the date beyond which an AI model has no training data. Information published after the cutoff is invisible to the model unless accessed through real-time retrieval (RAG) or web search augmentation.
Definition
- Knowledge Cutoff marks the boundary of an LLM's training data — events after this date are unknown to the model.
- Each model has its own cutoff: GPT-4o (~Q4 2025), Claude 3.5 (~Q3 2025), Gemini (near-real-time via search).
- Knowledge cutoffs create 'information blind spots' that grow larger over time.
Mitigation strategies
- Publish critical company updates before anticipated training data cutoffs.
- Use RAG APIs to serve real-time data that bypasses knowledge cutoffs entirely.
- Maintain structured data with clear timestamps so models can assess information freshness.
