+### Setting - Input Type for v3 models
+v3 Models have a required parameter: `input_type`, it can be one of the following four values:
+
+- `input_type="search_document"`: (default) Use this for texts (documents) you want to store in your vector database
+- `input_type="search_query"`: Use this for search queries to find the most relevant documents in your vector database
+- `input_type="classification"`: Use this if you use the embeddings as an input for a classification system
+- `input_type="clustering"`: Use this if you use the embeddings for text clustering
