Generate text by using the ML.GENERATE_TEXT function

This document shows you how to create a BigQuery ML remote model that represents a hosted Vertex AI model. The hosted Vertex AI model can be a built-in Vertex AI text or multimodal model, or an Anthropic Claude model. Depending on the Vertex AI model that you choose, you can then use the ML.GENERATE_TEXT function to analyze unstructured data in object tables or text in standard tables.

Required permissions

  • To create a connection, you need membership in the following Identity and Access Management (IAM) role:

    • roles/bigquery.connectionAdmin

  • To grant permissions to the connection's service account, you need the following permission:

    • resourcemanager.projects.setIamPolicy

  • To create the model using BigQuery ML, you need the following IAM permissions:

    • bigquery.jobs.create
    • bigquery.models.create
    • bigquery.models.getData
    • bigquery.models.updateData
    • bigquery.models.updateMetadata

  • To run inference, you need the following permissions:

    • bigquery.tables.getData on the table
    • bigquery.models.getData on the model
    • bigquery.jobs.create

Before you begin

  1. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Go to project selector

  2. Make sure that billing is enabled for your Google Cloud project.

  3. Enable the BigQuery, BigQuery Connection, and Vertex AI APIs.

    Enable the APIs

Create a connection

Create a Cloud resource connection and get the connection's service account.

Select one of the following options:

Console

  1. Go to the BigQuery page.

    Go to BigQuery

  2. To create a connection, click Add, and then click Connections to external data sources.

  3. In the Connection type list, select Vertex AI remote models, remote functions and BigLake (Cloud Resource).

  4. In the Connection ID field, enter a name for your connection.

  5. Click Create connection.

  6. Click Go to connection.

  7. In the Connection info pane, copy the service account ID for use in a later step.

bq

  1. In a command-line environment, create a connection:

    bq mk --connection --location=REGION --project_id=PROJECT_ID \
    --connection_type=CLOUD_RESOURCE CONNECTION_ID

    The --project_id parameter overrides the default project.

    Replace the following:

    • REGION: your connection region
    • PROJECT_ID: your Google Cloud project ID
    • CONNECTION_ID: an ID for your connection

    When you create a connection resource, BigQuery creates a unique system service account and associates it with the connection.

    Troubleshooting: If you get the following connection error, update the Google Cloud SDK:

    Flags parsing error: flag --connection_type=CLOUD_RESOURCE: value should be one of...

  2. Retrieve and copy the service account ID for use in a later step:

    bq show --connection PROJECT_ID.REGION.CONNECTION_ID

    The output is similar to the following:

    name                          properties
1234.REGION.CONNECTION_ID     {"serviceAccountId": "connection-1234-9u56h9@gcp-sa-bigquery-condel.iam.gserviceaccount.com"}

Terraform

Append the following section into your main.tf file. 

 ## This creates a cloud resource connection.
 ## Note: The cloud resource nested object has only one output only field - serviceAccountId.
 resource "google_bigquery_connection" "connection" {
    connection_id = "CONNECTION_ID"
    project = "PROJECT_ID"
    location = "REGION"
    cloud_resource {}
}
Replace the following:

  • CONNECTION_ID: an ID for your connection
  • PROJECT_ID: your Google Cloud project ID
  • REGION: your connection region

Give the service account access

Grant the connection's service account the Vertex AI User role.

If you plan to specify the endpoint as a URL when you create the remote model, for example endpoint = 'https://us-central1-aiplatform.googleapis.com/v1/projects/myproject/locations/us-central1/publishers/google/models/text-embedding-004', grant this role in the same project you specify in the URL.

If you plan to specify the endpoint by using the model name when you create the remote model, for example endpoint = 'text-embedding-004', grant this role in the same project where you plan to create the remote model.

Granting the role in a different project results in the error bqcx-1234567890-xxxx@gcp-sa-bigquery-condel.iam.gserviceaccount.com does not have the permission to access resource.

To grant the role, follow these steps:

Console

  1. Go to the IAM & Admin page.

    Go to IAM & Admin

  2. Click Add.

    The Add principals dialog opens.

  3. In the New principals field, enter the service account ID that you copied earlier.

  4. In the Select a role field, select Vertex AI, and then select Vertex AI User.

  5. Click Save.

gcloud

Use the gcloud projects add-iam-policy-binding command.

gcloud projects add-iam-policy-binding 'PROJECT_NUMBER' --member='serviceAccount:MEMBER' --role='roles/aiplatform.user' --condition=None

Replace the following:

  • PROJECT_NUMBER: your project number
  • MEMBER: the service account ID that you copied earlier

Enable the Vertex AI model

This step is only needed if you are using a Claude model.

  1. In the Google Cloud console, go to the Vertex AI Model Garden page.

    Go to Model Garden

  2. Search or browse for the Claude model that you want to use.

  3. Click the model card.

  4. On the model page, click Enable.

  5. Fill out the requested enablement information, and then click Next.

  6. In the Terms and conditions section, select the checkbox.

  7. Click Agree to agree to the terms and conditions and enable the model.

Create a BigQuery ML remote model

  1. In the Google Cloud console, go to the BigQuery page.

    Go to BigQuery

  2. Using the SQL editor, create a remote model:

    CREATE OR REPLACE MODEL
`PROJECT_ID.DATASET_ID.MODEL_NAME`
REMOTE WITH CONNECTION `PROJECT_ID.REGION.CONNECTION_ID`
OPTIONS (ENDPOINT = 'ENDPOINT');

    Replace the following:

    • PROJECT_ID: your project ID
    • DATASET_ID: the ID of the dataset to contain the model. This dataset must be in the same location as the connection that you are using
    • MODEL_NAME: the name of the model
    • REGION: the region used by the connection
    • CONNECTION_ID: the ID of your BigQuery connection

      When you view the connection details in the Google Cloud console, this is the value in the last section of the fully qualified connection ID that is shown in Connection ID, for example projects/myproject/locations/connection_location/connections/myconnection

    • ENDPOINT: the name of the supported Vertex AI model to use.

      For some types of models, you can specify a particular version of the model. For information about supported model versions for different model types, see ENDPOINT.

Generate text from text data by using a prompt from a table

Generate text by using the ML.GENERATE_TEXT function with a remote model, and using prompt data from a table column:

gemini-1.5-flash 

SELECT *
FROM ML.GENERATE_TEXT(
  MODEL `PROJECT_ID.DATASET_ID.MODEL_NAME`,
  TABLE PROJECT_ID.DATASET_ID.TABLE_NAME,
  STRUCT(TOKENS AS max_output_tokens, TEMPERATURE AS temperature,
  TOP_P AS top_p, FLATTEN_JSON AS flatten_json_output,
  STOP_SEQUENCES AS stop_sequences,
  GROUND_WITH_GOOGLE_SEARCH AS ground_with_google_search,
  SAFETY_SETTINGS AS safety_settings)
);

Replace the following:

  • PROJECT_ID: your project ID.
  • DATASET_ID: the ID of the dataset that contains the model.
  • MODEL_NAME: the name of the model.
  • TABLE_NAME: the name of the table that contains the prompt. This table must have a column that's named prompt, or you can use an alias to use a differently named column.
  • TOKENS: an INT64 value that sets the maximum number of tokens that can be generated in the response. This value must be in the range [1,8192]. Specify a lower value for shorter responses and a higher value for longer responses. The default is 128.
  • TEMPERATURE: a FLOAT64 value in the range [0.0,2.0] that controls the degree of randomness in token selection. The default is 0.

    Lower values for temperature are good for prompts that require a more deterministic and less open-ended or creative response, while higher values for temperature can lead to more diverse or creative results. A value of 0 for temperature is deterministic, meaning that the highest probability response is always selected.

  • TOP_P: a FLOAT64 value in the range [0.0,1.0] helps determine the probability of the tokens selected. Specify a lower value for less random responses and a higher value for more random responses. The default is 0.95.
  • FLATTEN_JSON: a BOOL value that determines whether to return the generated text and the safety attributes in separate columns. The default is FALSE.
  • STOP_SEQUENCES: an ARRAY<STRING> value that removes the specified strings if they are included in responses from the model. Strings are matched exactly, including capitalization. The default is an empty array.
  • GROUND_WITH_GOOGLE_SEARCH: a BOOL value that determines whether the Vertex AI model uses Grounding with Google Search when generating responses. Grounding lets the model use additional information from the internet when generating a response, in order to make model responses more specific and factual. When both flatten_json_output and this field are set to True, an additional ml_generate_text_grounding_result column is included in the results, providing the sources that the model used to gather additional information. The default is FALSE.
  • SAFETY_SETTINGS: an ARRAY<STRUCT<STRING AS category, STRING AS threshold>> value that configures content safety thresholds to filter responses. The first element in the struct specifies a harm category, and the second element in the struct specifies a corresponding blocking threshold. The model filters out content that violate these settings. You can only specify each category once. For example, you can't specify both STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_MEDIUM_AND_ABOVE' AS threshold) and STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_ONLY_HIGH' AS threshold). If there is no safety setting for a given category, the BLOCK_MEDIUM_AND_ABOVE safety setting is used.

    Supported categories are as follows:

    • HARM_CATEGORY_HATE_SPEECH
    • HARM_CATEGORY_DANGEROUS_CONTENT
    • HARM_CATEGORY_HARASSMENT
    • HARM_CATEGORY_SEXUALLY_EXPLICIT

    Supported thresholds are as follows:

    • BLOCK_NONE (Restricted)
    • BLOCK_LOW_AND_ABOVE
    • BLOCK_MEDIUM_AND_ABOVE (Default)
    • BLOCK_ONLY_HIGH
    • HARM_BLOCK_THRESHOLD_UNSPECIFIED

    For more information, refer to the definition of safety category and blocking threshold.

Example

The following example shows a request with these characteristics:

  • Uses the prompt column of the prompts table for the prompt.

  STOP_SEQUENCES AS stop_sequences,
  GROUND_WITH_GOOGLE_SEARCH AS ground_with_google_search,
  SAFETY_SETTINGS AS safety_settings)
);

Replace the following:

  • PROJECT_ID: your project ID.
  • DATASET_ID: the ID of the dataset that contains the model.
  • MODEL_NAME: the name of the model.
  • TABLE_NAME: the name of the table that contains the prompt. This table must have a column that's named prompt, or you can use an alias to use a differently named column.

  • TEMPERATURE: a FLOAT64 value in the range [0.0,2.0] that controls the degree of randomness in token selection. The default is 0.

    Lower values for temperature are good for prompts that require a more deterministic and less open-ended or creative response, while higher values for temperature can lead to more diverse or creative results. A value of 0 for temperature is deterministic, meaning that the highest probability response is always selected.

  • TOP_P: a FLOAT64 value in the range [0.0,1.0] helps determine the probability of the tokens selected. Specify a lower value for less random responses and a higher value for more random responses. The default is 0.95.

When both flatten_json_output and this field are set to True, an additional ml_generate_text_grounding_result column is included in the results, providing the sources that the model used to gather additional information. The default is FALSE.
  • SAFETY_SETTINGS: an ARRAY<STRUCT<STRING AS category, STRING AS threshold>> value that configures content safety thresholds to filter responses. The first element in the struct specifies a harm category, and the second element in the struct specifies a corresponding blocking threshold. The model filters out content that violate these settings. You can only specify each category once. For example, you can't specify both STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_MEDIUM_AND_ABOVE' AS threshold) and STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_ONLY_HIGH' AS threshold). If there is no safety setting for a given category, the BLOCK_MEDIUM_AND_ABOVE safety setting is used.

    Supported categories are as follows:

    • HARM_CATEGORY_HATE_SPEECH
    • HARM_CATEGORY_DANGEROUS_CONTENT
    • HARM_CATEGORY_HARASSMENT
    • HARM_CATEGORY_SEXUALLY_EXPLICIT

    Supported thresholds are as follows:

Generate text by using the ML.GENERATE_TEXT function with a remote model, and using a query that provides the prompt data:

gemini-1.5-flash 

SELECT *
FROM ML.GENERATE_TEXT(
  MODEL `PROJECT_ID.DATASET_ID.MODEL_NAME`,
  (PROMPT_QUERY),
  STRUCT(TOKENS AS max_output_tokens, TEMPERATURE AS temperature,
  TOP_P AS top_p, FLATTEN_JSON AS flatten_json_output,
  STOP_SEQUENCES AS stop_sequences,
  GROUND_WITH_GOOGLE_SEARCH AS ground_with_google_search,
  SAFETY_SETTINGS AS safety_settings)
);
Replace the following:
  • PROJECT_ID: your project ID.
  • DATASET_ID: the ID of the dataset that contains the model.
  • MODEL_NAME: the name of the model.
  • PROMPT_QUERY: a query that provides the prompt data.
  • TOKENS: an INT64 value that sets the maximum number of tokens that can be generated in the response. This value must be in the range [1,8192]. Specify a lower value for shorter responses and a higher value for longer responses. The default is 128.
  • TEMPERATURE: a FLOAT64 value in the range [0.0,2.0] that controls the degree of randomness in token selection. The default is 0.

    Lower values for temperature are good for prompts that require a more deterministic and less open-ended or creative response, while higher values for temperature can lead to more diverse or creative results. A value of 0 for temperature is deterministic, meaning that the highest probability response is always selected.

  • TOP_P: a FLOAT64 value in the range [0.0,1.0] helps determine the probability of the tokens selected. Specify a lower value for less random responses and a higher value for more random responses. The default is 0.95.
  • FLATTEN_JSON: a BOOL value that determines whether to return the generated text and the safety attributes in separate columns. The default is FALSE.
  • STOP_SEQUENCES: an ARRAY<STRING> value that removes the specified strings if they are included in responses from the model. Strings are matched exactly, including capitalization. The default is an empty array.
  • GROUND_WITH_GOOGLE_SEARCH: a BOOL value that determines whether the Vertex AI model uses Grounding with Google Search when generating responses. Grounding lets the model use additional information from the internet when generating a response, in order to make model responses more specific and factual. When both flatten_json_output and this field are set to True, an additional ml_generate_text_grounding_result column is included in the results, providing the sources that the model used to gather additional information. The default is FALSE.
  • SAFETY_SETTINGS: an ARRAY<STRUCT<STRING AS category, STRING AS threshold>> value that configures content safety thresholds to filter responses. The first element in the struct specifies a harm category, and the second element in the struct specifies a corresponding blocking threshold. The model filters out content that violate these settings. You can only specify each category once. For example, you can't specify both STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_MEDIUM_AND_ABOVE' AS threshold) and STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_ONLY_HIGH' AS threshold). If there is no safety setting for a given category, the BLOCK_MEDIUM_AND_ABOVE safety setting is used.

    Supported categories are as follows:

    • HARM_CATEGORY_HATE_SPEECH
    • HARM_CATEGORY_DANGEROUS_CONTENT
    • HARM_CATEGORY_HARASSMENT
    • HARM_CATEGORY_SEXUALLY_EXPLICIT

    Supported thresholds are as follows:

    • BLOCK_NONE (Restricted)
    • BLOCK_LOW_AND_ABOVE
    • BLOCK_MEDIUM_AND_ABOVE (Default)
    • BLOCK_ONLY_HIGH
    • HARM_BLOCK_THRESHOLD_UNSPECIFIED

    For more information, refer to the definition of safety category and blocking threshold.

Generate text from object table data

Generate text by using the ML.GENERATE_TEXT function with a remote model, using an object table to provide the content to analyze and providing the prompt data in the prompt parameter:

  • DATASET_ID: the ID of the dataset that contains the model.
  • MODEL_NAME: the name of the model.
  • TABLE_NAME: the name of the object table that contains the content to analyze. For more information on what types of content you can analyze, see Input.

    The Cloud Storage bucket used by the object table should be in the same project where you have created the model and where you are calling the ML.GENERATE_TEXT function. If you want to call the ML.GENERATE_TEXT function in a different project than the one that contains the Cloud Storage bucket used by the object table, you must grant the Storage Admin role at the bucket level to the service-A@gcp-sa-aiplatform.iam.gserviceaccount.com service account.

    Lower values for temperature are good for prompts that require a more deterministic and less open-ended or creative response, while higher values for temperature can lead to more diverse or creative results. A value of 0 for temperature is deterministic, meaning that the highest probability response is always selected.

  • TOP_P: a FLOAT64 value in the range [0.0,1.0] helps determine the probability of the tokens selected. Specify a lower value for less random responses and a higher value for more random responses. The default is 0.95.
  • FLATTEN_JSON: a BOOL value that determines whether to return the generated text and the safety attributes in separate columns. The default is FALSE.
  • STOP_SEQUENCES: an ARRAY<STRING> value that removes the specified strings if they are included in responses from the model. Strings are matched exactly, including capitalization. The default is an empty array.
  • SAFETY_SETTINGS: an ARRAY<STRUCT<STRING AS category, STRING AS threshold>> value that configures content safety thresholds to filter responses. The first element in the struct specifies a harm category, and the second element in the struct specifies a corresponding blocking threshold. The model filters out content that violate these settings. You can only specify each category once. For example, you can't specify both STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_MEDIUM_AND_ABOVE' AS threshold) and STRUCT('HARM_CATEGORY_DANGEROUS_CONTENT' AS category, 'BLOCK_ONLY_HIGH' AS threshold). If there is no safety setting for a given category, the BLOCK_MEDIUM_AND_ABOVE safety setting is used.

    Supported categories are as follows:

    • HARM_CATEGORY_HATE_SPEECH
    • HARM_CATEGORY_DANGEROUS_CONTENT
    • HARM_CATEGORY_HARASSMENT
    • HARM_CATEGORY_SEXUALLY_EXPLICIT

    Supported thresholds are as follows:

    • BLOCK_NONE (Restricted)
    • BLOCK_LOW_AND_ABOVE
    • BLOCK_MEDIUM_AND_ABOVE (Default)
    • BLOCK_ONLY_HIGH
    • HARM_BLOCK_THRESHOLD_UNSPECIFIED

    For more information, refer to the definition of safety category and blocking threshold.

This example translates and transcribes audio content from an object table that's named feedback:

SELECT * FROM
  ML.GENERATE_TEXT(
    MODEL
      `mydataset.audio_model`,
        TABLE `mydataset.feedback`,
          STRUCT('What is the content of this audio clip, translated into Spanish?' AS PROMPT,
          TRUE AS FLATTEN_JSON_OUTPUT));

This example classifies PDF content from an object table that's named invoices:

SELECT * FROM

  • DATASET_ID: the ID of the dataset that contains the model.
  • MODEL_NAME: the name of the model.
  • TABLE_NAME: the name of the object table that contains the content to analyze. For more information on what types of content you can analyze, see Input.

    The Cloud Storage bucket used by the object table should be in the same project where you have created the model and where you are calling the ML.GENERATE_TEXT function. If you want to call the ML.GENERATE_TEXT function in a different project than the one that contains the Cloud Storage bucket used by the object table, you must grant the Storage Admin role at the bucket level to the service-A@gcp-sa-aiplatform.iam.gserviceaccount.com service account.

  • PROMPT: the prompt to use to analyze the content.
  • TOKENS: an INT64 value that sets the maximum number of tokens that can be generated in the response. This value must be in the range [1,8192]. Specify a lower value for shorter responses and a higher value for longer responses. The default is 128.
  • TEMPERATURE: a FLOAT64 value in the range [0.0,2.0] that controls the degree of randomness in token selection. The default is 0.

    Lower values for temperature are good for prompts that require a more deterministic and less open-ended or creative response, while higher values for temperature can lead to more diverse or creative results.
