Class _TunableModelMixin (1.63.0)

_TunableModelMixin(model_id: str, endpoint_name: typing.Optional[str] = None)

Model that can be tuned with supervised fine tuning (SFT).

Methods

_TunableModelMixin

_TunableModelMixin(model_id: str, endpoint_name: typing.Optional[str] = None)

Creates a LanguageModel.

This constructor should not be called directly. Use LanguageModel.from_pretrained(model_name=...) instead.

Parameters
Name	Description
model_id	str Identifier of a Vertex LLM. Example: "text-bison@001"
endpoint_name	typing.Optional[str] Vertex Endpoint resource name for the model

) -> _LanguageModelTuningJob

Tunes a model based on training data.

This method launches and returns an asynchronous model tuning job. Usage:

tuning_job = model.tune_model(...)
... do some other work
tuned_model = tuning_job.get_tuned_model()  # Blocks until tuning is complete

Parameter
Name	Description
training_data	typing.Union[str, pandas.core.frame.DataFrame] A URI to training data in TSV (for embedding models), or JSON lines format, or a Pandas DataFrame.

Exceptions
Type	Description
ValueError	If the "tuning_job_location" value is not supported
ValueError	If the "tuned_model_location" value is not supported
RuntimeError	If the model does not support tuning
