Classes for working with the Gemini models.

Classes

AutomaticFunctionCallingResponder

AutomaticFunctionCallingResponder(max_automatic_function_calls: int = 1)

Responder that automatically responds to model's function calls.

    name: str,
    function: typing.Callable[[...], typing.Any],
    parameters: typing.Dict[str, typing.Any],
    description: typing.Optional[str] = None,
)

A function declaration plus a function.

Candidate

Candidate()

A response candidate generated by the model.

ChatSession

    model: vertexai.generative_models._generative_models._GenerativeModel,
    *,
    history: typing.Optional[
        typing.List[vertexai.generative_models._generative_models.Content]
    ] = None,
    response_validation: bool = True,
    responder: typing.Optional[
        vertexai.generative_models._generative_models.AutomaticFunctionCallingResponder
    ] = None,
    raise_on_blocked: typing.Optional[bool] = None
)

Chat session holds the chat history.

Content

Content(
    *,
    parts: typing.Optional[
        typing.List[vertexai.generative_models._generative_models.Part]

FinishReason

FinishReason(value)

The reason why the model stopped generating tokens. If empty, the model has not stopped generating the tokens.

Values: FINISH_REASON_UNSPECIFIED (0): The finish reason is unspecified. STOP (1): Natural stop point of the model or provided stop sequence. MAX_TOKENS (2): The maximum number of tokens as specified in the request was reached. SAFETY (3): The token generation was stopped as the response was flagged for safety reasons. NOTE: When streaming the Candidate.content will be empty if content filters blocked the output. RECITATION (4): The token generation was stopped as the response was flagged for unauthorized citations. OTHER (5): All other reasons that stopped the token generation BLOCKLIST (6): The token generation was stopped as the response was flagged for the terms which are included from the terminology blocklist.

    tools=[weather_tool],
)
chat = model.start_chat()
print(chat.send_message("What is the weather like in Boston?"))
print(chat.send_message(
    Part.from_function_response(
        name="get_current_weather",
