Dashscope

DashScopeEmbedding

Bases: MultiModalEmbedding

DashScope class for text embedding.

Parameters:

Name	Type	Description	Default
model_name	str	Model name for embedding. Defaults to DashScopeTextEmbeddingModels.TEXT_EMBEDDING_V2. Options are: - DashScopeTextEmbeddingModels.TEXT_EMBEDDING_V1 - DashScopeTextEmbeddingModels.TEXT_EMBEDDING_V2	TEXT_EMBEDDING_V2
text_type	str	The input type, ['query', 'document'], For asymmetric tasks such as retrieval, in order to achieve better retrieval results, it is recommended to distinguish between query text (query) and base text (document) types, clustering Symmetric tasks such as classification and classification do not need to be specially specified, and the system default value "document" can be used.	'document'
api_key	str	The DashScope api key.	None
