A knowledge cutoff date for a large language model (LLM) or AI system refers to the latest date of the data used to train the model. In other words, it is the point in time after which the AI does not have knowledge of events, information, or developments. As of June 2024, the knowledge cutoff dates for Claude models are as follows:
Claude 3 models (Opus, Sonnet, and Haiku): August 2023 Claude 3.5 Sonnet: April 2024 This means that Claude 3 models were trained on data up until August 2023, while the newer Claude 3.5 Sonnet has a more recent knowledge cutoff of April 2024. If asked about events or information after these respective dates, the models will not have knowledge of them. In comparison, some key competitors have the following knowledge cutoff dates:
ChatGPT (free version): September 2021 ChatGPT-4 (paid version): January 2022 for plugins mode, April 2023 for default mode Google Gemini 1.0 Pro: Early 2023 Anthropic is constantly working on updating Claude's training data. The release of Claude 3.5 Sonnet with its April 2024 cutoff demonstrates their commitment to keeping their models current.
