UnverifiedClaude Free, Pro and Max only use data to train models when the user actively permits it, with the exception of conversations flagged by safety review; after deletion they are cleared within 30 days; if the user permits training, de-identified conversations may be retained for up to 5 years.73% similarUnverifiedSending a chat message does not immediately retrain the model; training repeatedly adjusts model parameters through large amounts of data, takes weeks or even months, and is usually done offline; inference, by contrast, uses the already-trained fixed parameters to process new input.60% similar
