CrewAI soll ein einfaches Framework sein, um AI-Agents aufzusetzen. Lass es uns in diesem crewAI Tutorial einmal ausprobieren!

Neues git repo anlegen

Hach, der Geruch eines leeren Repos! Wir gehen auf github, erstellen ein neues repository (ich habe meins „crew“ genannt):

Anschließend clonen wir das repo und öffnen VSCode:

Dann folgen wir dem Setup unter https://github.com/crewAIInc/crewAI/blob/main/README.md

Schnell eine virtuelle Umgebung erstellt, dann crewAI installiert:

Beim Setup der .env.local File sich fragen, was Serper ist. Herausfinden, dass es eine günstige Google API ist. Kostenlosen Account erstellen und einen API Key erstellen. Sich den OpenAI Key schnappen und alles in die .env.local packen:

Copy/Paste des crewAI Beispiels, danach anpassen. In diesem Tutorial wollen wir unsere Gang eine Präsentation erstellen lassen, was zu tun ist, um in Deutschland der neuen E-Rechnungs-Regulierung zu entsprechen:

import os
from crewai import Agent, Task, Crew, Process
from crewai_tools import SerperDevTool

from dotenv import load_dotenv
load_dotenv()

search_tool = SerperDevTool()

# Define your agents with roles and goals
keynote_speaker = Agent(
  role='Senior Business Analyst',
  goal='Give a keynote on the current developments on E-Invoicing in Germany',
  backstory="""You work at a leading business consulting firm.
  Your expertise lies in helping businesses adopt E-Invoicing standards according to the EN 16931 regulation in Germany.
  You have a knack for dissecting complex regulations and presenting actionable insights.""",
  verbose=True,
  allow_delegation=True,
  # You can pass an optional llm attribute specifying what model you wanna use.
  # llm=ChatOpenAI(model_name="gpt-3.5", temperature=0.7),
  tools=[search_tool]
)
keynote_listener = Agent(
  role='Entrepreneur and managing director',
  goal='Understand what needs to be done to adopt E-Invoicing in Germany',
  backstory="""You are an entrepreneur and a managing director.
  You have heard about the need to adopt a new standard of E-Invoicing in Germany but are overwhelmed about what needs to be done.
  You love to give feedback on how information is presented and asking questions.""",
  verbose=True,
  allow_delegation=True
)

# Create tasks for your agents
task1 = Task(
  description="""Create a keynote presentation that helps the average German SMB owner what needs to be done to comply with the EN 16931 regulation""",
  expected_output="Full keynote presentation in bullet points",
  agent=keynote_speaker
)

task2 = Task(
  description="""Consume the keynote presentation and understand what needs to be done to comply with the EN 16931 regulation""",
  expected_output="Feedback to the keynote speaker",
  agent=keynote_listener
)

# Instantiate your crew with a sequential process
crew = Crew(
  agents=[keynote_speaker, keynote_listener],
  tasks=[task1,task2],
  verbose=True,
  process = Process.sequential
)

# Get your crew to work!
result = crew.kickoff()

print("######################")
print(result)

Das Ganze aufrufen, zurücklehnen und dem Wahnsinn zusehen:

Der erste Agent legt bereits los mit einer Google Suche zu aktuellen Entwicklungen zum Theme E-Rechnungen:

Alles klar, alles verstanden. Unser Keynote Speaker legt los und spuckt insgesamt 11 slides aus:

Output erzeugt, weiter geht’s:

OK, es wird interessant. Unser Keynote Listener legt los:

Ha! Die Keynote wird als Kontext mitgegeben und gleich eine Frage gestellt. Was muss ich denn jetzt tun? Unser Keynote Speaker legt also wieder los:

Und der Speaker gibt eine angepasste Version aus:

Welche wieder an unseren Listener geht:

Noch eine Feedback-Schleife:

Und eine letzte Ausgabe:

Und hier die finale Präsentation:

Keynote Presentation: Navigating E-Invoicing Compliance: EN 16931 in Germany

1. Introduction: Understanding E-Invoicing Compliance: EN 16931 in Germany

6. Benefits of E-Invoicing: Efficiency, cost savings, accuracy, and sustainability

  • Efficiency: Streamlined invoicing processes reduce manual handling and processing times.
  • Cost Savings: Lower costs associated with paper invoicing, printing, and postage.
  • Accuracy: Reduced errors and discrepancies with standardized data formats.
  • Sustainability: Environmentally friendly by reducing paper usage.

7. Common Challenges and Solutions: Integration with existing systems, compliance updates, and staff adaptation

  • Integration: Ensure your e-invoicing solution can seamlessly integrate with existing ERP and accounting systems.
  • Compliance Updates: Stay informed about regulatory changes and updates to maintain compliance.
