You can enable autonomous embedding generation on new or existing

## Feature Feature You can enable [autonomous embedding generation](https://cloud.google.com/bigquery/docs/autonomous-embedding-generation) on new or existing tables that you make with the [CREATE TABLE](https://cloud.google.com/bigquery/docs/autonomous-embedding-generation#create%5Fan%5Fautomatically%5Fgenerated%5Fembedding%5Fcolumn)or [ALTER TABLE](https://cloud.google.com/bigquery/docs/autonomous-embedding-generation#add%5Fan%5Fautomatically%5Fgenerated%5Fembedding%5Fcolumn%5Fto%5Fan%5Fexisting%5Ftable)statements. When you do this, BigQuery maintains a column of embeddings on the table based on a source column. When you add or modify data in the source column, BigQuery automatically generates or updates the embedding column for that data. This feature is[generally available](https://cloud.google.com/products#product-launch-stages)(GA).
