Foundation Models Text Generation API, REST: TextGenerationBatch.Completion

Field

Description

modelUri

string

The ID of the model to be used for batch completion generation.

completionOptions

CompletionOptions

Configuration options for completion generation.

sourceDatasetId

string

ID of the dataset containing the context for the completion model.

Includes only one of the fields sourceDatasetId.

Specifies the format of the request.

jsonObject

boolean

When set to true, the model will respond with a valid JSON object.
Be sure to explicitly ask the model for JSON.
Otherwise, it may generate excessive whitespace and run indefinitely until it reaches the token limit.

Includes only one of the fields jsonObject, jsonSchema.

Specifies the format of the model's response.

jsonSchema

JsonSchema

Enforces a specific JSON structure for the model's response based on a provided schema.

Includes only one of the fields jsonObject, jsonSchema.

Specifies the format of the model's response.

Field

Description

stream

boolean

Enables streaming of partially generated text.

temperature

number (double)

Affects creativity and randomness of responses. Should be a double number between 0 (inclusive) and 1 (inclusive).
Lower values produce more straightforward responses while higher values lead to increased creativity and randomness.
Default temperature: 0.3

maxTokens

string (int64)

The limit on the number of tokens used for single completion generation.
Must be greater than zero. This maximum allowed parameter value may depend on the model being used.

reasoningOptions

ReasoningOptions

Configures reasoning capabilities for the model, allowing it to perform internal reasoning before responding.

Field

Description

mode

enum (ReasoningMode)

Specifies the reasoning mode to be used.

• REASONING_MODE_UNSPECIFIED: Unspecified reasoning mode.
• DISABLED: Disables reasoning. The model will generate a response without performing any internal reasoning.
• ENABLED_HIDDEN: Enables reasoning in a hidden manner without exposing the reasoning steps to the user.

Field

Description

schema

object

The JSON Schema that the model's output must conform to.

Field

Description

id

string

ID of the operation.

description

string

Description of the operation. 0-256 characters long.

createdAt

string (date-time)

Creation timestamp.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

createdBy

string

ID of the user or service account who initiated the operation.

modifiedAt

string (date-time)

The time when the Operation resource was last modified.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

done

boolean

If the value is false, it means the operation is still in progress.
If true, the operation is completed, and either error or response is available.

metadata

BatchCompletionMetadata

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any.

error

Status

The error result of the operation in case of failure or cancellation.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

response

BatchCompletionResponse

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is google.protobuf.Empty.
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

• BATCH_INFERENCE_TASK_STATUS_UNSPECIFIED
• CREATED
• PENDING
• IN_PROGRESS
• COMPLETED

completedBatches

string (int64)

A number of currently completed batches of the completion task.

totalBatches

string (int64)

A number of total batches of the completion task.

Field

resultDatasetId

string

The ID of the dataset containing completion results.
