This assistant is powered by AI. The question you submit is sent to third-party AI providers (Alibaba Cloud DashScope and Volcengine Doubao) to produce an answer, together with public material from this site. The question and the matched public passages are transmitted to those providers. This site does not use your question for other purposes. The question and reply are kept on this server as a record of the request, and are not used for training.
