What is the knowledge cutoff for current Claude models?

Claude models are trained on data up to a specific date (the training data cutoff) and have the most reliable knowledge through a slightly earlier date (the reliable knowledge cutoff). Claude does not have access to real-time internet data during a conversation unless given a search tool.

Reliable knowledge cutoff indicates the date through which a model's knowledge is most extensive and reliable. Training data cutoff is the broader date range — the model may have some knowledge of events after the reliable cutoff but it is less complete and should be treated with more caution.

For tasks requiring current information (news, prices, live data), give Claude access to a web search tool or provide the relevant information directly in the prompt.
