        return combine_results(results)
    else:
        return perform_task(task)

def is_complex_task(task):
    # Define logic to determine if a task is complex
    return "complex" in task

def decompose_task(task):
    # Define logic to decompose task into sub-tasks
    return [f"{task}_part1", f"{task}_part2"]

        sub_tasks = decompose_task(task)
        with concurrent.futures.ThreadPoolExecutor() as executor:
            results = list(executor.map(multi_thread_recursive_solver, sub_tasks))
        return combine_results(results)
    else:
        return perform_task(task)

# Reuse the previously defined functions is_complex_task, decompose_task, combine_results, and perform_task

task = "complex_task"
print(multi_thread_recursive_solver(task))

With these building blocks in place, you can develop a robust and efficient LLM agent framework application capable of handling complex tasks and providing accurate answers. Next, we will explore how to develop the core of your LLM agent, integrating these components into a cohesive system.

Developing the Core of Your LLM Agent

The core of your LLM agent is the central processing unit that orchestrates all its operations. This section covers the different types of solvers used in the agent core, the integration process for various components such as tools, planners, and memory modules, and the evaluation of the mental model to ensure the agent's effectiveness.

Developing a robust core is crucial for the agent's ability to handle complex tasks efficiently and accurately.

Introduction to Different Solver Types for the Agent Core

Choosing the right solver type for your agent core is essential for optimizing performance and task management. Different solvers offer unique benefits and are suited to various levels of complexity in problem-solving.

Linear Solver

  • Simple Execution: Follows a straightforward, linear path to solve tasks.

  • Ease of Implementation: Suitable for simpler tasks that do not require complex decision-making processes.

def linear_solver(tasks):
    results = []
    for task in tasks:
        result = perform_task(task)
        results.append(result)
    return results

def perform_task(task):
    # Define task execution logic here
    return f"Result of {task}"

tasks = ["task1", "task2", "task3"]
print(linear_solver(tasks))

Single-Thread Recursive Solver

  • Depth-First Approach: Solves tasks by recursively breaking them into sub-tasks and processing them individually.

  • Improved Problem-Solving: Suitable for tasks that require a more detailed and step-by-step approach.

def single_thread_recursive_solver(task):
    if is_complex_task(task):
        sub_tasks = decompose_task(task)
        results = [single_thread_recursive_solver(sub_task) for sub_task in sub_tasks]
        return combine_results(results)
    else:
        return perform_task(task)

def is_complex_task(task):
    # Define logic to determine if a task is complex
    return "complex" in task

def decompose_task(task):
    # Define logic to decompose task into sub-tasks
    return [f"{task}_part1", f"{task}_part2"]

def combine_results(results):
    # Define logic to combine results of sub-tasks
    return " & ".join(results)

def perform_task(task):
    # Define task execution logic here
    return f"Result of {task}"

task = "complex_task"
print(single_thread_recursive_solver(task)

Multi-Thread Recursive Solver

  • Parallel Processing: Executes multiple tasks or sub-tasks simultaneously, improving efficiency and reducing latency.

  • High Complexity Handling: Ideal for handling highly complex tasks that benefit from concurrent execution.

import concurrent.futures

def multi_thread_recursive_solver(task):
    if is_complex_task(task):
        sub_tasks = decompose_task(task)
        with concurrent.futures.ThreadPoolExecutor() as executor:
            results = list(executor.map(multi_thread_recursive_solver, sub_tasks))
        return combine_results(results)
    else:
        return perform_task(task)

# Reuse the previously defined functions is_complex_task, decompose_task, combine_results, and perform_task

task = "complex_task"
print(multi_thread_recursive_solver(task))

Integration Process of Tools, Planner, and Memory Module in the Agent Setup

Integrating the various components of your LLM agent—such as tools, the planner, and the memory module—is critical to ensure they work together seamlessly and efficiently. This process involves setting up communication channels and workflows between these components.

Tools Integration

  • Setup and Configuration: Initialize and configure the tools required for the agent to perform specific tasks.

  • Inter-Component Communication: Ensure that the tools can communicate effectively with other components like the planner and memory module.

class Agent:
    def __init__(self, tools, planner, memory):
        self.tools = tools
        self.planner = planner
        self.memory = memory

    def integrate_tools(self):
        for tool in self.tools:
            tool.setup()
        print("Tools integrated successfully")

class Tool:
    def setup(self):
        # Define tool setup logic here
        print("Tool setup complete")

tools = [Tool(), Tool()]
agent = Agent(tools, None, None)
agent.integrate_tools()

Planner Integration

  • Task Decomposition: The planner decomposes complex tasks into manageable sub-tasks.

  • Task Assignment: Assigns sub-tasks to the appropriate tools and manages their execution.

class Planner:
    def __init__(self):
        self.plan = []

    def create_plan(self, task):
        self.plan = self.decompose_task(task)

    def decompose_task(self, task):
        # Decompose the task into sub-tasks
        return [f"{task}_sub1", f"{task}_sub2"]

    def assign_tasks(self, agent):
        for sub_task in self.plan:
            agent.execute_task(sub_task)

planner = Planner()
planner.create_plan("complex_task")

Memory Module Integration

  • Information Retrieval: Retrieves relevant information from past interactions to aid in current task processing.

class MemoryModule:
    def __init__(self):
        self.memory = []

    def store_interaction(self, question, answer):
        self.memory.append({"question": question, "answer": answer})

    def retrieve_interaction(self, question):
        for interaction in self.memory:
            if interaction["question"] == question:
                return interaction["answer"]
        return None

memory = MemoryModule()
memory.store_interaction("What is the capital of France?", "Paris")
