```

Methods

compute_tokens

compute_tokens(
    contents: ContentsType,
) -> google.cloud.aiplatform_v1beta1.types.llm_utility_service.ComputeTokensResponse

Computes tokens.

Returns
Type	Description
A ComputeTokensResponse object that has the following attributes	tokens_info: Lists of tokens_info from the input. The input contents: ContentsType could have multiple string instances and each tokens_info item represents each string instance. Each token info consists tokens list, token_ids list and a role.

compute_tokens_async

compute_tokens_async(
    contents: ContentsType,
) -> google.cloud.aiplatform_v1beta1.types.llm_utility_service.ComputeTokensResponse

Computes tokens asynchronously.

Returns
Type	Description
And awaitable for a ComputeTokensResponse object that has the following attributes	tokens_info: Lists of tokens_info from the input. The input contents: ContentsType could have multiple string instances and each tokens_info item represents each string instance. Each token info consists tokens list, token_ids list and a role.

count_tokens

count_tokens(
    contents: ContentsType,
    *,
    tools: typing.Optional[
        typing.List[vertexai.generative_models._generative_models.Tool]
    ] = None
) -> google.cloud.aiplatform_v1beta1.types.prediction_service.CountTokensResponse

Counts tokens.

Returns
Type	Description
A CountTokensResponse object that has the following attributes	total_tokens: The total number of tokens counted across all instances from the request. total_billable_characters: The total number of billable characters counted across all instances from the request.

count_tokens_async

count_tokens_async(
    contents: ContentsType,
    *,
    tools: typing.Optional[
        typing.List[vertexai.generative_models._generative_models.Tool]
    ] = None
) -> google.cloud.aiplatform_v1beta1.types.prediction_service.CountTokensResponse

Counts tokens asynchronously.

Returns
Type	Description
And awaitable for a CountTokensResponse object that has the following attributes	total_tokens: The total number of tokens counted across all instances from the request. total_billable_characters: The total number of billable characters counted across all instances from the request.

from_cached_content

from_cached_content(
    cached_content: typing.Union[str, CachedContent],
    *,
    generation_config: typing.Optional[GenerationConfigType] = None,
    safety_settings: typing.Optional[SafetySettingsType] = None
) -> _GenerativeModel

Creates a model from cached content.

Creates a model instance with an existing cached content. The cached content becomes the prefix of the requesting contents.

generate_content

generate_content(
    contents: ContentsType,
    *,
    generation_config: typing.Optional[GenerationConfigType] = None,
    safety_settings: typing.Optional[SafetySettingsType] = None,

) -> typing.Union[
    vertexai.generative_models._generative_models.GenerationResponse,
    typing.Iterable[vertexai.generative_models._generative_models.GenerationResponse],
]

Generates content.

generate_content_async

generate_content_async(
    contents: ContentsType,
    *,
    generation_config: typing.Optional[GenerationConfigType] = None,
