agentchat.conversable_agent

ConversableAgent​

class ConversableAgent(LLMAgent)

(In preview) A class for generic conversable agents which can be configured as assistant or user proxy.

After receiving each message, the agent will send a reply to the sender unless the msg is a termination msg. For example, AssistantAgent and UserProxyAgent are subclasses of this class, configured with different default settings.

To modify auto reply, override generate_reply method. To disable/enable human response in every turn, set human_input_mode to "NEVER" or "ALWAYS". To modify the way to get human input, override get_human_input method. To modify the way to execute code blocks, single code block, or function call, override execute_code_blocks, run_code, and execute_function methods respectively.

DEFAULT_CONFIG​

False or dict, the default config for llm inference

MAX_CONSECUTIVE_AUTO_REPLY​

maximum number of consecutive auto replies (subject to future change)

__init__​

def __init__(name: str,
             system_message: Optional[Union[
                 str, List]] = "You are a helpful AI Assistant.",
             is_termination_msg: Optional[Callable[[Dict], bool]] = None,
             max_consecutive_auto_reply: Optional[int] = None,
             human_input_mode: Literal["ALWAYS", "NEVER",
                                       "TERMINATE"] = "TERMINATE",
             function_map: Optional[Dict[str, Callable]] = None,
             code_execution_config: Union[Dict, Literal[False]] = False,
             llm_config: Optional[Union[Dict, Literal[False]]] = None,
             default_auto_reply: Union[str, Dict] = "",
             description: Optional[str] = None,
             chat_messages: Optional[Dict[Agent, List[Dict]]] = None)

Arguments:

  • name str - name of the agent.
  • system_message str or list - system message for the ChatCompletion inference.
  • is_termination_msg function - a function that takes a message in the form of a dictionary and returns a boolean value indicating if this received message is a termination message. The dict can contain the following keys: "content", "role", "name", "function_call".
  • max_consecutive_auto_reply int - the maximum number of consecutive auto replies. default to None (no limit provided, class attribute MAX_CONSECUTIVE_AUTO_REPLY will be used as the limit in this case). When set to 0, no auto reply will be generated.
  • human_input_mode str - whether to ask for human inputs every time a message is received. Possible values are "ALWAYS", "TERMINATE", "NEVER". (1) When "ALWAYS", the agent prompts for human input every time a message is received. Under this mode, the conversation stops when the human input is "exit", or when is_termination_msg is True and there is no human input. (2) When "TERMINATE", the agent only prompts for human input only when a termination message is received or the number of auto reply reaches the max_consecutive_auto_reply. (3) When "NEVER", the agent will never prompt for human input. Under this mode, the conversation stops when the number of auto reply reaches the max_consecutive_auto_reply or when is_termination_msg is True.
  • function_map dict[str, callable] - Mapping function names (passed to openai) to callable functions, also used for tool calls.
  • code_execution_config dict or False - config for the code execution. To disable code execution, set to False. Otherwise, set to a dictionary with the following keys:
    • work_dir (Optional, str): The working directory for the code execution. If None, a default working directory will be used. The default working directory is the "extensions" directory under "path_to_autogen".
    • use_docker (Optional, list, str or bool): The docker image to use for code execution. Default is True, which means the code will be executed in a docker container. A default list of images will be used. If a list or a str of image name(s) is provided, the code will be executed in a docker container with the first image successfully pulled. If False, the code will be executed in the current environment. We strongly recommend using docker for code execution.
    • timeout (Optional, int): The maximum execution time in seconds.
    • last_n_messages (Experimental, int or str): The number of messages to look back for code execution. If set to 'auto', it will scan backwards through all messages arriving since the agent last spoke, which is typically the last time execution was attempted. (Default: auto)
  • llm_config dict or False or None - llm inference configuration. Please refer to OpenAIWrapper.create for available options. When using OpenAI or Azure OpenAI endpoints, please specify a non-empty 'model' either in llm_config or in each config of 'config_list' in llm_config. To disable llm-based auto reply, set to False. When set to None, will use self.DEFAULT_CONFIG, which defaults to False.
  • default_auto_reply str or dict - default auto reply when no code execution or llm-based reply is generated.
  • description str - a short description of the agent. This description is used by other agents (e.g. the GroupChatManager) to decide when to call upon this agent. (Default: system_message)
  • chat_messages dict or None - the previous chat messages that this agent had in the past with other agents. Can be used to give the agent a memory by providing the chat history. This will allow the agent to resume previous had conversations. Defaults to an empty chat history.

name​

@property
def name() -> str

Get the name of the agent.

description​

@property
def description() -> str

Get the description of the agent.

description​

@description.setter
def description(description: str)

Set the description of the agent.

code_executor​

@property

register_reply​

def register_reply(trigger: Union[Type[Agent], str, Agent,
                                  Callable[[Agent], bool], List],
                   reply_func: Callable,
                   position: int = 0,
                   config: Optional[Any] = None,
                   reset_config: Optional[Callable] = None,
                   *,
                   ignore_async_in_sync_chat: bool = False,
                   remove_other_reply_funcs: bool = False)

Register a reply function.

The reply function will be called when the trigger matches the sender. The function registered later will be checked earlier by default. To change the order, set the position to a positive integer.

Both sync and async reply functions can be registered. The sync reply function will be triggered from both sync and async chats. However, an async reply function will only be triggered from async chats (initiated with ConversableAgent.a_initiate_chat). If an async reply function is registered and a chat is initialized with a sync function, ignore_async_in_sync_chat determines the behaviour as follows: if ignore_async_in_sync_chat is set to False (default value), an exception will be raised, and if ignore_async_in_sync_chat is set to True, the reply function will be ignored.

Arguments:

  • trigger Agent class, str, Agent instance, callable, or list - the trigger. If a class is provided, the reply function will be called when the sender is an instance of the class. If a string is provided, the reply function will be called when the sender's name matches the string. If an agent instance is provided, the reply function will be called when the sender is the agent instance. If a callable is provided, the reply function will be called when the callable returns True. If a list is provided, the reply function will be called when any of the triggers in the list is activated. If None is provided, the reply function will be called only when the sender is None.

  • Note - Be sure to register None as a trigger if you would like to trigger an auto-reply function with non-empty messages and sender=None.

  • reply_func Callable - the reply function. The function takes a recipient agent, a list of messages, a sender agent and a config as input and returns a reply message.

      ```python
      def reply_func(
          recipient: ConversableAgent,
          messages: Optional[List[Dict]] = None,
          sender: Optional[Agent] = None,
          config: Optional[Any] = None,
      ) -> Tuple[bool, Union[str, Dict, None]]:
      ```

  • position int - the position of the reply function in the reply function list. The function registered later will be checked earlier by default. To change the order, set the position to a positive integer.

  • config Any - the config to be passed to the reply function. When an agent is reset, the config will be reset to the original value.

  • reset_config Callable - the function to reset the config. The function returns None. Signature: def reset_config(config: Any)

  • ignore_async_in_sync_chat bool - whether to ignore the async reply function in sync chats. If False, an exception will be raised if an async reply function is registered and a chat is initialized with a sync function.

  • remove_other_reply_funcs bool - whether to remove other reply functions when registering this reply function.

replace_reply_func​

def replace_reply_func(old_reply_func: Callable, new_reply_func: Callable)

Arguments:

  • old_reply_func Callable - the old reply function to be replaced.
  • new_reply_func Callable - the new reply function to replace the old one.

                          reply_func_from_nested_chats: Union[
                              str, Callable] = "summary_from_nested_chats",
                          position: int = 2,
                          **kwargs) -> None

  • trigger Agent class, str, Agent instance, callable, or list - refer to register_reply for details.
  • reply_func_from_nested_chats Callable, str - the reply function for the nested chat. The function takes a chat_queue for nested chat, recipient agent, a list of messages, a sender agent and a config as input and returns a reply message. Default to "summary_from_nested_chats", which corresponds to a built-in reply function that get summary from the nested chat_queue. 
    def reply_func_from_nested_chats(
        chat_queue: List[Dict],
        recipient: ConversableAgent,
        messages: Optional[List[Dict]] = None,
        sender: Optional[Agent] = None,
        config: Optional[Any] = None,
    ) -> Tuple[bool, Union[str, Dict, None]]:

Returns:

The last message exchanged with the agent.

use_docker​

@property
def use_docker() -> Union[bool, str, None]

Bool value of whether to use docker to execute the code, or str value of the docker image name to use, or None when code execution is disabled.

send​

def send(message: Union[Dict, str],
         recipient: Agent,
         request_reply: Optional[bool] = None,
         silent: Optional[bool] = False)

Send a message to another agent.

Arguments:

  • message dict or str - message to be sent. The message could contain the following fields:
    • content (str or List): Required, the content of the message. (Can be None)
    • function_call (str): the name of the function to be called.
    • name (str): the name of the function to be called.
    • role (str): the role of the message, any role that is not "function" will be modified to "assistant".
    • context (dict): the context of the message, which will be passed to OpenAIWrapper.create. For example, one agent can send a message A as:
{
    "content": lambda context: context["use_tool_msg"],
    "context": {
        "use_tool_msg": "Use tool X if they are relevant."
    }
}

Next time, one agent can send a message B with a different "use_tool_msg". Then the content of message A will be refreshed to the new "use_tool_msg". So effectively, this provides a way for an agent to send a "link" and modify the content of the "link" later.

  • recipient Agent - the recipient of the message.
  • request_reply bool or None - whether to request a reply from the recipient.
  • silent bool or None - (Experimental) whether to print the message sent.

Raises:

    }
}

Next time, one agent can send a message B with a different "use_tool_msg". Then the content of message A will be refreshed to the new "use_tool_msg". So effectively, this provides a way for an agent to send a "link" and modify the content of the "link" later.

  • recipient Agent - the recipient of the message.
  • request_reply bool or None - whether to request a reply from the recipient.

initiate_chat​

def initiate_chat(recipient: "ConversableAgent",
                  clear_history: bool = True,
                  silent: Optional[bool] = False,
                  cache: Optional[AbstractCache] = None,
                  max_turns: Optional[int] = None,
                  summary_method: Optional[Union[
                      str, Callable]] = DEFAULT_SUMMARY_METHOD,
                  summary_args: Optional[dict] = {},
                  message: Optional[Union[Dict, str, Callable]] = None,
                  **kwargs) -> ChatResult

Initiate a chat with the recipient agent.

Reset the consecutive auto reply counter. If clear_history is True, the chat history with the recipient agent will be cleared.

Arguments:

  • recipient - the recipient agent.

  • clear_history bool - whether to clear the chat history with the agent. Default is True.

  • silent bool or None - (Experimental) whether to print the messages for this conversation. Default is False.

  • cache AbstractCache or None - the cache client to be used for this conversation. Default is None.

  • max_turns int or None - the maximum number of turns for the chat between the two agents. One turn means one conversation round trip. Note that this is different from max_consecutive_auto_reply which is the maximum number of consecutive auto replies; and it is also different from max_rounds in GroupChat which is the maximum number of rounds in a group chat session. If max_turns is set to None, the chat will continue until a termination condition is met. Default is None.

  • summary_method str or callable - a method to get a summary from the chat. Default is DEFAULT_SUMMARY_METHOD, i.e., "last_msg".

    Supported strings are "last_msg" and "reflection_with_llm":

    • when set to "last_msg", it returns the last message of the dialog as the summary.
    • when set to "reflection_with_llm", it returns a summary extracted using an llm client. llm_config must be set in either the recipient or sender.

    A callable summary_method should take the recipient and sender agent in a chat as input and return a string of summary. E.g.,

    def my_summary_method(
        sender: ConversableAgent,
        recipient: ConversableAgent,
        summary_args: dict,
    ):
        return recipient.last_message(sender)["content"]

  • summary_args dict - a dictionary of arguments to be passed to the summary_method. One example key is "summary_prompt", and value is a string of text used to prompt a LLM-based agent (the sender or receiver agent) to reflect on the conversation and extract a summary when summary_method is "reflection_with_llm". The default summary_prompt is DEFAULT_SUMMARY_PROMPT, i.e., "Summarize takeaway from the conversation. Do not add any introductory phrases. If the intended request is NOT properly addressed, please point it out."

  • message str, dict or Callable - the initial message to be sent to the recipient. Needs to be provided. Otherwise, input() will be called to get the initial message.

    • If a string or a dict is provided, it will be used as the initial message. generate_init_message is called to generate the initial message for the agent based on this string and the context. If dict, it may contain the following reserved fields (either content or tool_calls need to be provided).

    1. "content": content of the message, can be None.

    2. "function_call": a dictionary containing the function name and arguments. (deprecated in favor of "tool_calls")

    3. "tool_calls": a list of dictionaries containing the function name and arguments.

    4. "role": role of the message, can be "assistant", "user", "function". This field is only needed to distinguish between "function" or "assistant"/"user".

    5. "name": In most cases, this field is not needed. When the role is "function", this field is needed to indicate the function name.

    6. "context" (dict): the context of the message, which will be passed to OpenAIWrapper.create.

    • If a callable is provided, it will be called to get the initial message in the form of a string or a dict. If the returned type is dict, it may contain the reserved fields mentioned above.

    Example of a callable message (returning a string):

    def my_message(sender: ConversableAgent, recipient: ConversableAgent, context: dict) -> Union[str, Dict]:
        carryover = context.get("carryover", "")
        if isinstance(message, list):
            carryover = carryover[-1]
        final_msg = "Write a blogpost." + "\nContext: \n" + carryover
        return final_msg

    Example of a callable message (returning a dict):

    def my_message(sender: ConversableAgent, recipient: ConversableAgent, context: dict) -> Union[str, Dict]:
        final_msg = {}
        carryover = context.get("carryover", "")
        if isinstance(message, list):
            carryover = carryover[-1]
        final_msg["content"] = "Write a blogpost." + "\nContext: \n" + carryover
        final_msg["context"] = {"prefix": "Today I feel"}
        return final_msg

  • **kwargs - any additional information. It has the following reserved fields:

    • "carryover": a string or a list of string to specify the carryover information to be passed to this chat. If provided, we will combine this carryover (by attaching a "context: " string and the carryover content after the message content) with the "message" content when generating the initial chat message in generate_init_message.
    • "verbose": a boolean to specify whether to print the message and carryover in a chat. Default is False.

Raises:

  • RuntimeError - if any async reply functions are registered and not ignored in sync chat.

Returns:

  • ChatResult - an ChatResult object.
