This page describes how to generate embeddings using registered model endpoints.
Before you begin
Make sure that you have registered your model endpoint with Model endpoint management. For more information, see Register a model endpoint with model endpoint management
Generate embeddings
Use the google_ml.embedding()
SQL function to call the registered model endpoint with
the text embedding model type to generate embeddings.
To call the model and generate embeddings, use the following SQL query:
a
sql
SELECT
google_ml.embedding(
model_id => 'MODEL_ID',
content => 'CONTENT');
Replace the following:
MODEL_ID
: the model ID you defined when registering the model endpoint.CONTENT
: the text to translate into a vector embedding.
Examples
Some examples for generating embeddings using registered model endpoint are listed in this section.
Text embedding models with built-in support
To generate embeddings for a registered textembedding-gecko@002
model endpoint, run the following statement:
SELECT
google_ml.embedding(
model_id => 'textembedding-gecko@002',
content => 'AlloyDB is a managed, cloud-hosted SQL database service');
To generate embeddings for a registered text-embedding-ada-002
model endpoint by OpenAI, run the following statement:
SELECT
google_ml.embedding(
model_id => 'text-embedding-ada-002',
content => 'e-mail spam');
To generate embeddings for a registered text-embedding-3-small
or text-embedding-3-large
model endpoints by OpenAI, run the following statement:
SELECT
google_ml.embedding(
model_id => 'text-embedding-3-small',
content => 'Vector embeddings in AI');
