    REST Resource: projects.locations.models

    Resource: Model

    A trained machine learning Model.

    Fields
    name string

    The resource name of the Model.

    versionId string

    Output only. Immutable. The version id of the model. A new version is committed when a new model version is uploaded or trained under an existing model id. It is an auto-incrementing decimal number in string representation.

    versionAliases[] string

    user provided version aliases so that a model version can be referenced via alias (i.e. projects/{project}/locations/{location}/models/{modelId}@{version_alias} instead of auto-generated version id (i.e. projects/{project}/locations/{location}/models/{modelId}@{versionId}) . The format is [a-z][a-zA-Z0-9-]{0,126}[a-z0-9] to distinguish from versionId. A default version alias will be created for the first version of the model, and there must be exactly one default version alias for a model.

    versionCreateTime string ( Timestamp format)

    Output only. timestamp when this version was created.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    versionUpdateTime string ( Timestamp format)

    Output only. timestamp when this version was most recently updated.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    displayName string

    Required. The display name of the Model. The name can be up to 128 characters long and can consist of any UTF-8 characters.

    description string

    The description of the Model.

    versionDescription string

    The description of this version.

    defaultCheckpointId string

    The default checkpoint id of a model version.

    predictSchemata object ( PredictSchemata )

    The schemata that describe formats of the Model's predictions and explanations as given and returned via PredictionService.Predict and PredictionService.Explain .

    metadataSchemaUri string

    Immutable. Points to a YAML file stored on Google Cloud Storage describing additional information about the Model, that is specific to it. Unset if the Model does not have any additional information. The schema is defined as an OpenAPI 3.0.2 Schema Object . AutoML Models always have this field populated by Vertex AI, if no additional metadata is needed, this field is set to an empty string. Note: The URI given on output will be immutable and probably different, including the URI scheme, than the one given on input. The output URI will point to a location where the user only has a read access.

    metadata value ( Value format)

    Immutable. An additional information about the Model; the schema of the metadata can be found in metadataSchema . Unset if the Model does not have any additional information.

    supportedExportFormats[] object ( ExportFormat )

    Output only. The formats in which this Model may be exported. If empty, this Model is not available for export.

    trainingPipeline string

    Output only. The resource name of the TrainingPipeline that uploaded this Model, if any.

    containerSpec object ( ModelContainerSpec )

    Input only. The specification of the container that is to be used when deploying this Model. The specification is ingested upon ModelService.UploadModel , and all binaries it contains are copied and stored internally by Vertex AI. Not required for AutoML Models.

    artifactUri string

    Immutable. The path to the directory containing the Model artifact and any of its supporting files. Not required for AutoML Models.

    supportedDeploymentResourcesTypes[] enum ( DeploymentResourcesType )

    Output only. When this Model is deployed, its prediction resources are described by the prediction_resources field of the Endpoint.deployed_models object. Because not all Models support all resource configuration types, the configuration types this Model supports are listed here. If no configuration types are listed, the Model cannot be deployed to an Endpoint and does not support online predictions ( PredictionService.Predict or PredictionService.Explain ). Such a Model can serve predictions by using a BatchPredictionJob , if it has at least one entry each in supportedInputStorageFormats and supportedOutputStorageFormats .

    supportedInputStorageFormats[] string

    Output only. The formats this Model supports in BatchPredictionJob.input_config . If PredictSchemata.instance_schema_uri exists, the instances should be given as per that schema.

    The possible formats are:

    • jsonl The JSON Lines format, where each instance is a single line. uses GcsSource .

    • csv The CSV format, where each instance is a single comma-separated line. The first line in the file is the header, containing comma-separated field names. uses GcsSource .

    • tf-record The TFRecord format, where each instance is a single record in tfrecord syntax. uses GcsSource .

    • tf-record-gzip Similar to tf-record , but the file is gzipped. uses GcsSource .

    • bigquery Each instance is a single row in BigQuery. uses BigQuerySource .

    • file-list Each line of the file is the location of an instance to process, uses gcsSource field of the InputConfig object.

    If this Model doesn't support any of these formats it means it cannot be used with a BatchPredictionJob . However, if it has supportedDeploymentResourcesTypes , it could serve online predictions by using PredictionService.Predict or PredictionService.Explain .

    supportedOutputStorageFormats[] string

    Output only. The formats this Model supports in BatchPredictionJob.output_config . If both PredictSchemata.instance_schema_uri and PredictSchemata.prediction_schema_uri exist, the predictions are returned together with their instances. In other words, the prediction has the original instance data first, followed by the actual prediction content (as per the schema).

    The possible formats are:

    • jsonl The JSON Lines format, where each prediction is a single line. uses GcsDestination .

    • csv The CSV format, where each prediction is a single comma-separated line. The first line in the file is the header, containing comma-separated field names. uses GcsDestination .

    • bigquery Each prediction is a single row in a BigQuery table, uses BigQueryDestination .

    If this Model doesn't support any of these formats it means it cannot be used with a BatchPredictionJob . However, if it has supportedDeploymentResourcesTypes , it could serve online predictions by using PredictionService.Predict or PredictionService.Explain .

    createTime string ( Timestamp format)

    Output only. timestamp when this Model was uploaded into Vertex AI.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    updateTime string ( Timestamp format)

    Output only. timestamp when this Model was most recently updated.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    deployedModels[] object ( DeployedModelRef )

    Output only. The pointers to DeployedModels created from this Model. Note that Model could have been deployed to endpoints in different Locations.

    explanationSpec object ( ExplanationSpec )

    The default explanation specification for this Model.

    The Model can be used for requesting explanation after being deployed if it is populated. The Model can be used for batch explanation if it is populated.

    All fields of the explanationSpec can be overridden by explanationSpec of DeployModelRequest.deployed_model , or explanationSpec of BatchPredictionJob .

    If the default explanation specification is not set for this Model, this Model can still be used for requesting explanation by setting explanationSpec of DeployModelRequest.deployed_model and for batch explanation by setting explanationSpec of BatchPredictionJob .

    etag string

    Used to perform consistent read-modify-write updates. If not set, a blind "overwrite" update happens.
