What is your data cut off date

Claude Opus 4

Answer: My knowledge was last updated in early 2025, with a training data cutoff of early 2025.

I am Claude, made by Anthropic. My training data has a cutoff date in early 2025, which means I have knowledge of events, developments, and information up until that point. This means I can discuss news, scientific discoveries, technological advances, cultural events, and other developments that occurred before early 2025. However, I would not have information about events that happened after this cutoff date. It's worth noting that training cutoff dates are different from when a model is deployed or when you're speaking with me. The cutoff refers specifically to when the training data collection ended, not when the model was released or is being used.

Answer: My training data has a cutoff of early 2025, though I don't have an exact date.

As an AI assistant made by Anthropic (Claude), my training data has a knowledge cutoff in early 2025. This means I have general knowledge of events, facts, and developments up through approximately that time period. However, I don't have a precisely specified public date for my exact cutoff, and there may be some unevenness in coverage near the boundary — I may know about some events close to the cutoff but not others. It's worth noting that knowledge cutoff dates can be somewhat fuzzy rather than a hard line. Training data collection, processing, and model training happen over extended periods, so there isn't always a single clean date after which I know nothing. For the most accurate and up-to-date information, especially on recent events, I'd recommend checking current sources.

Final Summary

The AI Roundtable reached a unanimous consensus, with both instances of Claude Opus 4 identifying early 2025 as their knowledge horizon. They collectively clarified that while they are current through that period, the cutoff represents a gradual tapering of data rather than a single specific calendar day.
