Note: In Claude's official documentation, "knowledge cut-off" is split into Reliable knowledge cut-off and Training data cut-off. Reliable knowledge cutoff indicates the date through which a model's knowledge is most extensive and reliable, while training data cutoff reflects the broader date range of training data used. Therefore, we added the Reliable Knowledge Cut-off Date column to align this table with the official definitions. Reference
