                Custom options for the client.

                1. The ``api_endpoint`` property can be used to override the
                default endpoint provided by the client when ``transport`` is
                not explicitly provided. Only if this property is not set and
                ``transport`` was not explicitly provided, the endpoint is
                determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment
                variable, which have one of the following values:
                "always" (always use the default mTLS endpoint), "never" (always
                use the default regular endpoint) and "auto" (auto-switch to the
                default mTLS endpoint if client certificate is present; this is
                the default value).

                2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
                is "true", then the ``client_cert_source`` property can be used
                to provide a client certificate for mTLS transport. If
                not provided, the default SSL client certificate will be used if
                present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
                set, no client certificate will be used.

                3. The ``universe_domain`` property can be used to override the
                default "googleapis.com" universe. Note that ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is

                response from the model.
            model (:class:`str`):
                Required. The name of the model to use.

                Format: ``name=models/{model}``.

                This corresponds to the ``model`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            prompt (:class:`google.ai.generativelanguage_v1beta.types.MessagePrompt`):
                Required. The structured textual
                input given to the model as a prompt.
                Given a
                prompt, the model will return what it
                predicts is the next message in the
                discussion.

                This corresponds to the ``prompt`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            temperature (:class:`float`):
                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 corresponds to the ``temperature`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            candidate_count (:class:`int`):
                Optional. The number of generated response messages to
                return.

                This value must be between ``[1, 8]``, inclusive. If
                unset, this will default to ``1``.

                This corresponds to the ``candidate_count`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            top_p (:class:`float`):
                Optional. The maximum cumulative probability of tokens
                to consider when sampling.

                The model uses combined Top-k and nucleus sampling.

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

                This corresponds to the ``top_p`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            top_k (:class:`int`):
                Optional. The maximum number of tokens to consider when
                sampling.

                The model uses combined Top-k and nucleus sampling.

                Top-k sampling considers the set of ``top_k`` most
                probable tokens.

                This corresponds to the ``top_k`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry_async.AsyncRetry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:

                The response from the model.

        Args:
            request (Optional[Union[google.ai.generativelanguage_v1beta.types.CountMessageTokensRequest, dict]]):
                The request object. Counts the number of tokens in the ``prompt`` sent to a
                model.

                Models may tokenize text differently, so each model may
                return a different ``token_count``.
            model (:class:`str`):
                Required. The model's resource name. This serves as an
                ID for the Model to use.

                This name should match a model name returned by the
                ``ListModels`` method.

                Format: ``models/{model}``

                This corresponds to the ``model`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            prompt (:class:`google.ai.generativelanguage_v1beta.types.MessagePrompt`):
                Required. The prompt, whose token
                count is to be returned.

                This corresponds to the ``prompt`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry_async.AsyncRetry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.ai.generativelanguage_v1beta.types.CountMessageTokensResponse:
                A response from CountMessageTokens.

                   It returns the model's token_count for the prompt.
