+## Get embeddings generation task details
+
+* Besides viewing the list of tasks in the [AI Tasks - list view](../../../ai-integration/ai-tasks-list-view.mdx) in the Studio,  
+  you can also retrieve embeddings generation task details programmatically.
+
+* This is useful when issuing a vector search query that references an embeddings generation task,  
+  where it's important to verify that the task exists beforehand. For example:  
+  * when [Querying pre-made embeddings generated by tasks](../../../ai-integration/vector-search/vector-search-using-dynamic-query#querying-pre-made-embeddings-generated-by-tasks)
+  * or when [Indexing numerical data and querying using text input](../../../ai-integration/vector-search/vector-search-using-static-index#indexing-numerical-data-and-querying-using-text-input)
+
+* There are two ways to check if an embeddings generation task exists:
+  * Using `GetOngoingTaskInfoOperation`.  
+  * Accessing the full list of embeddings generation tasks from the database record.
