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 the ``api_endpoint``
property still takes precedence; and ``universe_domain`` is
currently not supported for mTLS.

the model.
model (str):
Required. The name of the ``Model`` to use for
generating the completion.
Format: ``name=models/{model}``.
This corresponds to the ``model`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
contents (MutableSequence[google.ai.generativelanguage_v1.types.Content]):
Required. The content of the current conversation with
the model.
For single-turn queries, this is a single instance. For
multi-turn queries like
`chat <https://ai.google.dev/gemini-api/docs/text-generation#chat>`__,
this is a repeated field that contains the conversation
history and the latest request.
This corresponds to the ``contents`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
retry (google.api_core.retry.Retry): 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:
Iterable[google.ai.generativelanguage_v1.types.GenerateContentResponse]:
Response from the model supporting multiple candidate
responses.
Safety ratings and content filtering are reported for
both prompt in
GenerateContentResponse.prompt_feedback and for each
candidate in finish_reason and in safety_ratings. The
API: - Returns either all requested candidates or
none of them - Returns no candidates at all only if
there was something wrong with the prompt (check
prompt_feedback) - Reports feedback on each candidate
in finish_reason and safety_ratings.
