+## FAQ
+
+<details>
+  <summary>1. Why does the model have so good generalization performance, and can be used to many task scenarios out of the box?</summary>
+
+<!-- ### Why does the model have so good generalization performance, and can be used to many task scenarios out of the box? -->
+
+The excellent generalization ability of the model comes from the diversity of pre-training data, as well as the design of different optimization objectives for multi-task scenarios when pre-training the model.
+
+Specifically, the mainly technical features:
+
+1) The first is large-scale weak label contrastive learning. Industry experience shows that out-of-the-box language models perform poorly on Embedding-related tasks. However, due to the high cost of supervised data annotation and acquisition, large-scale, high-quality weak label learning has become an optional technical route. By extracting weak labels from semi-structured data such as forums, news, Q&A communities, and encyclopedias on the Internet, and using large models to perform low-quality filtering, 1 billion-level weakly supervised text pair data is obtained.
+
+2) The second is high-quality supervised learning. We have collected and compiled a large-scale open source annotated sentence pair data set, including a total of 30 million sentence pair samples in encyclopedia, education, finance, medical care, law, news, academia and other fields. At the same time, we mine hard-to-negative sample pairs and use contrastive learning to better optimize the model.
+
+3) The last step is the optimization of retrieval tasks. Considering that search, question and answer, RAG and other scenarios are important application positions for the Embedding model, in order to enhance the cross-domain and cross-scenario performance of the model, we have specially optimized the model for retrieval tasks. The core lies in mining data from question and answer, retrieval and other data. Hard-to-negative samples use sparse and dense retrieval and other methods to construct a million-level hard-to-negative sample pair data set, which significantly improves the cross-domain retrieval performance of the model.

+  <summary>4. What are the follow-up plans?</summary>
+
+<!-- ### What are the follow-up plans? -->
+
+We will continue to work hard to provide the community with embedding models that have excellent performance, lightweight reasoning, and can be used in multiple scenarios out of the box. At the same time, we will gradually integrate embedding into the existing technology ecosystem and grow with the community!
