Here's a practical implementation of a multi-agent system for content creation:
from crewai import Agent, Task, Crew
from datetime import datetime
class ContentCreationCrew:
def __init__(self):
# Define specialized agents
self.researcher = Agent(
name="Researcher",
role="Gathers information and sources",
goal="Provide comprehensive research for content",
backstory="Academic researcher with expertise in information synthesis"
)
self.writer = Agent(
name="Writer",
role="Creates initial drafts",
goal="Produce engaging, well-structured content",
backstory="Professional writer with SEO expertise"
)
self.editor = Agent(
name="Editor",
role="Refines and polishes content",
goal="Ensure clarity, accuracy, and quality",
backstory="Experienced editor with attention to detail"
)
self.seo_specialist = Agent(
name="SEO Specialist",
role="Optimizes for search engines",
goal="Maximize content visibility and ranking",
backstory="Digital marketing expert with SEO certification"
)
def create_article(self, topic):
# Create the crew
crew = Crew(
agents=[self.researcher, self.writer, self.editor, self.seo_specialist],
context=f"Creating article about {topic}",
verbose=True
)
# Define the workflow
tasks = [
Task(description=f"Research {topic} comprehensively", agent=self.researcher),
Task(description=f"Write initial draft about {topic}", agent=self.writer),
Task(description=f"Edit and refine the draft", agent=self.editor),
Task(description=f"Optimize for SEO with focus on {topic}", agent=self.seo_specialist)
]
# Execute
results = crew.kickoff(tasks)
# Compile final output
final_content = "\n\n".join([result.output for result in results])
return final_content
# Usage
crew = ContentCreationCrew()
article = crew.create_article("multi-agent AI systems")
print(article)
Advanced Patterns and Techniques
As multi-agent systems mature, several advanced patterns are emerging.
Hierarchical Agent Structures
Complex problems often benefit from hierarchical organization:
# Manager agents overseeing specialized teams
class ManagerAgent(Agent):
def __init__(self, name, team):
super().__init__(name=name, role="Manager", goal="Coordinate team efforts")
self.team = team
def coordinate(self, task):
# Delegate subtasks to team members
subtasks = self.breakdown(task)
results = []
for subtask in subtasks:
# Assign to appropriate team member
best_agent = self.select_agent(subtask)
result = best_agent.execute(subtask)
results.append(result)
return self.combine_results(results)
class SpecializedTeam:
def __init__(self, members):
self.members = members
def execute_task(self, task):
# Parallel execution of subtasks
results = [agent.execute(subtask)
for agent, subtask in zip(self.members, task.subtasks)]
return results
Dynamic Role Assignment
Modern agent fleets can adapt roles based on context:
from typing import Dict, List
class DynamicCrew:
def __init__(self, agents: List[Agent]):
self.agents = agents
self.skills_matrix = self.build_skills_matrix()
def build_skills_matrix(self):
matrix = {}
for agent in self.agents:
matrix[agent.name] = agent.skills
return matrix
def assign_roles(self, task_requirements: Dict[str, float]):
# Match agent skills to task requirements
assignments = {}
for skill, required_score in task_requirements.items():
best_match = None
best_score = 0
for agent_name, skills in self.skills_matrix.items():
if skill in skills:
skill_score = skills[skill]
if skill_score > required_score and skill_score > best_score:
best_match = agent_name
best_score = skill_score
if best_match:
assignments[skill] = best_match
return assignments
def execute_dynamic_task(self, task):
# Dynamically assign agents based on task needs
requirements = task.get_requirements()
assignments = self.assign_roles(requirements)
# Create specialized crew
specialized_crew = [self.get_agent_by_name(name)
for name in assignments.values()]
# Execute with specialized team
return Crew(agents=specialized_crew).kickoff(task.steps)
Performance Optimization Strategies
Maximizing the effectiveness of agent fleets requires attention to several performance factors.
Communication Optimization
Efficient communication patterns are critical:
class OptimizedCommunication:
def __init__(self, agents):
self.agents = agents
self.message_queue = Queue()
self.communication_protocol = self.setup_protocol()
def setup_protocol(self):
# Implement efficient communication patterns
return {
'broadcast': self.broadcast_message,
'direct': self.direct_message,
'context_share': self.share_context
}
def broadcast_message(self, message):
# Send message to all agents efficiently
for agent in self.agents:
agent.receive_message(message)
def direct_message(self, sender, recipient_name, message):
# Direct communication between specific agents
recipient = next(a for a in self.agents
if a.name == recipient_name)
recipient.receive_message(f"{sender.name}: {message}")
def share_context(self, context):
# Share relevant context across agents
for agent in self.agents:
agent.update_context(context)
Resource Management
Effective resource allocation ensures optimal performance:
class ResourceManager:
def __init__(self, agents):
self.agents = agents
self.resource_pool = self.initialize_resources()
def initialize_resources(self):
return {
'compute': Resource(capacity=100, allocated=0),
'memory': Resource(capacity=64, allocated=0),
'bandwidth': Resource(capacity=1000, allocated=0)
}
def allocate_resources(self, task):
# Calculate resource requirements
requirements = task.calculate_resource_needs()
# Check availability
if self.can_allocate(requirements):
self.allocate(requirements)
return True
return False
def can_allocate(self, requirements):
return (self.resource_pool['compute'].available >= requirements['compute'] and
self.resource_pool['memory'].available >= requirements['memory'] and
self.resource_pool['bandwidth'].available >= requirements['bandwidth'])
def allocate(self, requirements):
self.resource_pool['compute'].allocate(requirements['compute'])
self.resource_pool['memory'].allocate(requirements['memory'])
self.resource_pool['bandwidth'].allocate(requirements['bandwidth'])
