string

Output only. The tuned model name. A unique name will be generated on create. Example: tunedModels/az2mb0bpw6i If displayName is set on create, the id portion of the name will be set by concatenating the words of the displayName with hyphens and adding a random portion for uniqueness. Example: displayName = "Sentence Translator" name = "tunedModels/sentence-translator-u3b7m"

string

Optional. The name to display for this model in user interfaces. The display name must be up to 40 characters including spaces.

string

Optional. A short description of this model.

enum (State)

Output only. The state of the tuned model.

string (Timestamp format)

Output only. The timestamp when this model was created.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

string (Timestamp format)

Output only. The timestamp when this model was updated.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

object (TuningTask)

Required. The tuning task that creates the tuned model.

object (TunedModelSource)

Optional. TunedModel to use as the starting point for training the new model.

string

Immutable. The name of the Model to tune. Example: models/text-bison-001

number

Optional. Controls the randomness of the output.

Values can range over [0.0,1.0], inclusive. A value closer to 1.0 will produce responses that are more varied, while a value closer to 0.0 will typically result in less surprising responses from the model.

This value specifies default to be the one used by the base model while creating the model.

number

Optional. For Nucleus sampling.

Nucleus sampling considers the smallest set of tokens whose probability sum is at least topP.

This value specifies default to be the one used by the base model while creating the model.

integer

Optional. For Top-k sampling.

Top-k sampling considers the set of topK most probable tokens. This value specifies default to be used by the backend while making the call to the model.

This value specifies default to be the one used by the base model while creating the model.

{
  "tunedModel": string,
  "baseModel": string
}

string

Immutable. The name of the TunedModel to use as the starting point for training the new model. Example: tunedModels/my-tuned-model

string

Output only. The name of the base Model this TunedModel was tuned from. Example: models/text-bison-001

string (Timestamp format)

Output only. The timestamp when tuning this model started.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

string (Timestamp format)
