  * This is the default embedding post process function, the expected result from the model in two cases:
- * 1. A list of list of float for APIs embedding type is not enabled.
- * 2. A map of string to list of list of number for APIs that embedding type is enabled.
+ * 1. A {@link List} of {@link List} of {@link Float} {@link Float} for APIs embedding type is not enabled.
+ * 2. A map of string to {@link List} of {@link List} of {@link Number} for APIs that embedding type is enabled.
  * An example of enabled embedding type is cohere v2, the embedding API requires embedding_types as a mandatory field in the request body:

  * Currently, OpenAI Cohere and default sagemaker embedding models are using this function.
