Domain name for API request: es.intl.tencentcloudapi.com.
Embedding is a technology that maps high-dimensional data to a low-dimensional space, usually used for converting unstructured data such as text, images, or audio into vector representation, making it easier to input into machine models for processing, and the distance between vectors can reflect the similarity between objects.
This API has a model dimensional call limit. Each model has a qps limit of 20. If you need to increase the concurrent limit, please contact us (https://www.tencentcloud.com/act/event/Online_service?from_cn_redirect=1).
A maximum of 1000 requests can be initiated per second for this API.
