Enum Constant Details

FINE_TUNING

@Stability(Stable)
public static final CustomizationType FINE_TUNING

Fine-tuning.

Provide labeled data in order to train a model to improve performance on specific tasks.

CONTINUED_PRE_TRAINING

@Stability(Stable)
public static final CustomizationType CONTINUED_PRE_TRAINING

Continued pre-training.

Provide unlabeled data to pre-train a foundation model by familiarizing it with certain types of inputs.

DISTILLATION

@Stability(Stable)
public static final CustomizationType DISTILLATION

Distillation.

With Model Distillation, you can generate synthetic responses from a large foundation model (teacher) and use that data to train a smaller model (student) for your specific use-case.

Method Details

values

public static CustomizationType[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CustomizationType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
