This means that its parameters are not automatically changed during users’ work or based on the submitted documents. Customer documents, classification results, and corrections made by users are not used to train, retrain, or automatically modify the model. The data contained in the documents is not transferred to external AI models for the purpose of performing classification. Processing takes place within the system’s infrastructure and is used solely to carry out operations related to document classification and anonymization. This approach helps maintain a stable and predictable way of operating the classifier and reduces the risk of using the contents of documents for purposes other than performing the system’s functions. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://bluurdoc.bluur.ai/en/getting-started/quick-start/key-features/ai-model-security.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
