The ML.GENERATE_TEXT function

Gemini

 ML.GENERATE_TEXT( MODEL `PROJECT_ID.DATASET.MODEL`, { TABLE `PROJECT_ID.DATASET.TABLE` | (QUERY_STATEMENT) }, STRUCT( [MAX_OUTPUT_TOKENS AS max_output_tokens] [, TOP_P AS top_p] [, TEMPERATURE AS temperature] [, FLATTEN_JSON_OUTPUT AS flatten_json_output] [, STOP_SEQUENCES AS stop_sequences] [, GROUND_WITH_GOOGLE_SEARCH AS ground_with_google_search] [, SAFETY_SETTINGS AS safety_settings] [, REQUEST_TYPE AS request_type]) ) 

Arguments

ML.GENERATE_TEXT takes the following arguments:

• PROJECT_ID: the project that contains the resource.

• DATASET: the dataset that contains the resource.

• MODEL: the name of the remote model over the Vertex AI model. For more information about how to create this type of remote model, see The CREATE MODEL statement for remote models over LLMs.

  You can confirm what model is used by the remote model by opening the Google Cloud console and looking at the Remote endpoint field in the model details page.

• TABLE: the name of the BigQuery table that contains the prompt data. The text in the column that's named prompt is sent to the model. If your table does not have a prompt column, use the QUERY_STATEMENT argument instead and provide a SELECT statement that includes an alias for an existing table column. An error occurs if no prompt column is available.

• QUERY_STATEMENT: the GoogleSQL query that generates the prompt data. The query must produce a column named prompt. Within the query, you can provide the prompt value in the following ways:

  • Specify a STRING value. For example, ('Write a poem about birds').

  • Specify a STRUCT value that contains one or more fields. You can use the following types of fields within the STRUCT value:

    Field type	Description	Examples
    STRING	A string literal, or the name of a STRING column.	String literal: 'Is Seattle a US city?' String column name: my_string_column
    ARRAY<STRING>	You can only use string literals in the array.	Array of string literals: ['Is ', 'Seattle', ' a US city']
    ObjectRefRuntime	An ObjectRefRuntime value returned by the OBJ.GET_ACCESS_URL function. The OBJ.GET_ACCESS_URL function takes an ObjectRef value as input, which you can provide by either specifying the name of a column that contains ObjectRef values, or by constructing an ObjectRef value. ObjectRefRuntime values must have the access_url.read_url and details.gcs_metadata.content_type elements of the JSON value populated.	Function call with ObjectRef column: OBJ.GET_ACCESS_URL(my_objectref_column, 'r') Function call with constructed ObjectRef value: OBJ.GET_ACCESS_URL(OBJ.MAKE_REF('gs://image.jpg', 'myconnection'), 'r')
    ARRAY<ObjectRefRuntime>	ObjectRefRuntime values returned from multiple calls to the OBJ.GET_ACCESS_URL function. The OBJ.GET_ACCESS_URL function takes an ObjectRef value as input, which you can provide by either specifying the name of a column that contains ObjectRef values, or by constructing an ObjectRef value. ObjectRefRuntime values must have the access_url.read_url and details.gcs_metadata.content_type elements of the JSON value populated.	Function calls with ObjectRef columns: [OBJ.GET_ACCESS_URL(my_objectref_column1, 'r'), OBJ.GET_ACCESS_URL(my_objectref_column2, 'r')] Function calls with constructed ObjectRef values: [OBJ.GET_ACCESS_URL(OBJ.MAKE_REF('gs://image1.jpg', 'myconnection'), 'r'), OBJ.GET_ACCESS_URL(OBJ.MAKE_REF('gs://image2.jpg', 'myconnection'), 'r')]

    The function combines STRUCT fields similarly to a CONCAT operation and concatenates the fields in their specified order. The same is true for the elements of any arrays used within the struct. The following table shows some examples of STRUCT prompt values and how they are interpreted:

    Struct field types	Struct value	Semantic equivalent
    STRUCT<STRING>	('Describe the city of Seattle')	'Describe the city of Seattle'
    STRUCT<STRING, STRING, STRING>	('Describe the city ', my_city_column, ' in 15 words')	'Describe the city my_city_column_value in 15 words'
    STRUCT<STRING, ARRAY<STRING>>	('Describe ', ['the city of', 'Seattle'])	'Describe the city of Seattle'
    STRUCT<STRING, ObjectRefRuntime>	('Describe this city', OBJ.GET_ACCESS_URL(image_objectref_column, 'r'))	'Describe this city' image
    STRUCT<STRING, ObjectRefRuntime, ObjectRefRuntime>	('If the city in the first image is within the country of the second image, provide a ten word description of the city', OBJ.GET_ACCESS_URL(city_image_objectref_column, 'r'), OBJ.GET_ACCESS_URL(country_image_objectref_column, 'r'))	'If the city in the first image is within the country of the second image, provide a ten word description of the city' city_image country_image

• MAX_OUTPUT_TOKENS: an INT64 value that sets the maximum number of tokens that can be generated in the response. A token might be smaller than a word and is approximately four characters. One hundred tokens correspond to approximately 60-80 words. 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 1024.

• TOP_P: a FLOAT64 value in the range [0.0,1.0] that changes how the model selects tokens for output. Specify a lower value for less random responses and a higher value for more random responses. The default is 0.95.

  Tokens are selected from the most to least probable until the sum of their probabilities equals the TOP_P value. For example, if tokens A, B, and C have a probability of 0.3, 0.2, and 0.1, and the TOP_P value is 0.5, then the model selects either A or B as the next token by using the TEMPERATURE value and doesn't consider C.

• TEMPERATURE: a FLOAT64 value in the range [0.0,1.0] that controls the degree of randomness in token selection. Lower TEMPERATURE values are good for prompts that require a more deterministic and less open-ended or creative response, while higher TEMPERATURE values can lead to more diverse or creative results. A TEMPERATURE value of 0 is deterministic, meaning that the highest probability response is always selected. The default is 0.

• FLATTEN_JSON_OUTPUT: a BOOL value that determines whether the JSON content returned by the function is parsed into 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. You can only use this argument with Gemini 1.5 pro and Gemini 1.5 flash models. 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.

• REQUEST_TYPE: a STRING value that specifies the type of inference request to send to the Gemini model. The request type determines what quota the request uses. Valid values are as follows:

  • DEDICATED: The ML.GENERATE_TEXT function only uses Provisioned Throughput quota. The ML.GENERATE_TEXT function returns the error Provisioned throughput is not purchased or is not active if Provisioned Throughput quota isn't available.
  • SHARED: The ML.GENERATE_TEXT function only uses dynamic shared quota (DSQ), even if you have purchased Provisioned Throughput quota.

  • UNSPECIFIED: The ML.GENERATE_TEXT function uses quota as follows:

    • If you haven't purchased Provisioned Throughput quota, the ML.GENERATE_TEXT function uses DSQ quota.
    • If you have purchased Provisioned Throughput quota, the ML.GENERATE_TEXT function uses the Provisioned Throughput quota first. If requests exceed the Provisioned Throughput quota, the overflow traffic uses DSQ quota.

  The default value is UNSPECIFIED.

Details

The model and input table must be in the same region.

Claude

You must enable Claude models in Vertex AI before you can use them. For more information, see Enable a partner model.

Arguments

ML.GENERATE_TEXT takes the following arguments:

• PROJECT_ID: the project that contains the resource.

• DATASET: the dataset that contains the resource.

• MODEL: the name of the remote model over the Vertex AI model. For more information about how to create this type of remote model, see The CREATE MODEL statement for remote models over LLMs.

  You can confirm what model is used by the remote model by opening the Google Cloud console and looking at the Remote endpoint field in the model details page.

• TABLE: the name of the BigQuery table that contains the prompt data. The text in the column that's named prompt is sent to the model. If your table does not have a prompt column, use the QUERY_STATEMENT argument instead and provide a SELECT statement that includes an alias for an existing table column. An error occurs if no prompt column is available.

• QUERY_STATEMENT: the GoogleSQL query that generates the prompt data. The query must produce a column named prompt.

• MAX_OUTPUT_TOKENS: an INT64 value that sets the maximum number of tokens that can be generated in the response. A token might be smaller than a word and is approximately four characters. One hundred tokens correspond to approximately 60-80 words. This value must be in the range [1,4096]. Specify a lower value for shorter responses and a higher value for longer responses. The default is 1024.

• TOP_K: an INT64 value in the range [1,40] that changes how the model selects tokens for output. Specify a lower value for less random responses and a higher value for more random responses. If you don't specify a value, the model determines an appropriate value.

  A TOP_K value of 1 means the next selected token is the most probable among all tokens in the model's vocabulary, while a TOP_K value of 3 means that the next token is selected from among the three most probable tokens by using the TEMPERATURE value.

  For each token selection step, the TOP_K tokens with the highest probabilities are sampled. Then tokens are further filtered based on the TOP_P value, with the final token selected using temperature sampling.

• TOP_P: a FLOAT64 value in the range [0.0,1.0] that changes how the model selects tokens for output. Specify a lower value for less random responses and a higher value for more random responses. If you don't specify a value, the model determines an appropriate value.

  Tokens are selected from the most to least probable until the sum of their probabilities equals the TOP_P value. For example, if tokens A, B, and C have a probability of 0.3, 0.2, and 0.1, and the TOP_P value is 0.5, then the model selects either A or B as the next token by using the TEMPERATURE value and doesn't consider C.

• FLATTEN_JSON_OUTPUT: a BOOL value that determines whether the JSON content returned by the function is parsed into separate columns. The default is FALSE.
