If a list of specifications (not BaseModelBackend instances) is provided, they will be instantiated using ModelFactory. (default: :obj:ModelPlatformType.DEFAULT with ModelType.DEFAULT)
  • memory (AgentMemory, optional): The agent memory for managing chat messages. If None, a :obj:ChatHistoryMemory will be used. (default: :obj:None)

  • pause_event (Optional[Union[threading.Event, asyncio.Event]]): Event to signal pause of the agent’s operation. When clear, the agent will pause its execution. Use threading.Event for sync operations or asyncio.Event for async operations. (default: :obj:None)
  • prune_tool_calls_from_memory (bool): Whether to clean tool call messages from memory after response generation to save token usage. When enabled, removes FUNCTION/TOOL role messages and ASSISTANT messages with tool_calls after each step. (default: :obj:False)
  • retry_attempts (int, optional): Maximum number of retry attempts for rate limit errors. (default: :obj:3)
  • retry_delay (float, optional): Initial delay in seconds between retries. Uses exponential backoff. (default: :obj:1.0)
  • step_timeout (Optional[float], optional): Timeout in seconds for the entire step operation. If None, no timeout is applied. (default: :obj:None)
  • stream_accumulate (bool, optional): When True, partial streaming updates return accumulated content (current behavior). When False, partial updates return only the incremental delta. (default: :obj:True)
