Abstract
A large language model (LLM) is trained to classify Uniform Resource Locator (URL) requests using a data that has been labeled with a domain-to-category database of corresponding, suitable categories for web content. This model can then be distilled using a student model trained to reproduce the behavior of the tuned large language model. The resulting student model can be deployed inline as a content filter for, e.g., content-based filtering of web requests from endpoints behind a firewall or other network device. While this disclosure emphasizes filtering of outbound URL's from network endpoints, it will be understood that the techniques described herein may also or instead be used to create inbound content filters using similarly derived student models that have been trained to identify content based on metadata, text content, image content, and so forth.
