To start building your own agent, follow the steps listed.

1. set environmental variable OPENAI_API_KEY

   # .env
   OPENAI_API_KEY=sk-...
   

2. bring in SDKs from CEO

   • Agent lets you instantiate an agent.

   • Personality is an enumeration class used for customizing personalities of agents.

     • Personality.PRUDENT makes the agent's behavior more cautious.

     • Personality.INQUISITIVE encourages the agent to be more proactive in trying and exploring.

   • get_openai_model gives you a BaseChatModel as thought engine.

   • @ability(brain: BaseChatModel, cache: bool = True, cache_dir: str = '') is a decorator which lets you declare a function as an Ability.

   • @agentic(agent: Agent) is a decorator which lets you declare a function as an AgenticAbility.

   from ceo import (
       Agent,
       Personality,
       get_openai_model,
       ability,
       agentic
   )

3. declare functions as basic abilities

   @ability
   def calculator(expr: str) -> float:
       # this function only accepts a single math expression
       return simplify(expr)
   
   @ability
   def write_file(filename: str, content: str) -> str:
       with open(filename, 'w', encoding='utf-8') as f:
           f.write(content)
       return f'{content} written to {filename}.'

4. instantiate an agent

   You can grant abilities to agents while instantiating them.

   model = get_openai_model()
   agent = Agent(abilities=[calculator, write_file], brain=model, name='CEO', personality=Personality.INQUISITIVE)

   • You can also grant more abilities to agents later:

     agent.grant_ability(calculator)

     or

     agent.grant_abilities([calculator])

   • To deprive abilities:

     agent.deprive_ability(calculator)

     or

     agent.deprive_abilities([calculator])

   You can change an agent's personality using method change_personality(personality: Personality)

   agent.change_personality(Personality.PRUDENT)

5. assign a request to your agent

   agent.assign("Here is a sphere with radius of (1 * 9.5 / 2 * 2) cm and pi here is 3.14159, find the area and volume respectively then write the results into a file called 'result.txt'.")

6. leave the rest to your agent

   response = agent.just_do_it()
   print(response)

ceo also supports multi-agent collaboration scenario, declare a function as agent calling ability with @agentic(agent: Agent), then grant it to an agent. See example.

• Compound Tasks

  1. Find the surface area and volume of a sphere and write the results into a file.

• Multi-agent

  1. Ask the suitable agents to find the surface area and volume of a sphere and write the results into a file.

     import logging
     
     from sympy import simplify
     from dotenv import load_dotenv
     from ceo import (
         Agent,
         Personality,
         get_openai_model,
         agentic,
         ability
     )
     
     load_dotenv()
     logging.getLogger('ceo').setLevel(logging.DEBUG)
     model = get_openai_model()
     
     
     @ability
     def calculator(expr: str) -> float:
         # this function only accepts a single math expression
         return simplify(expr)
     
     
     @ability
     def write_file(filename: str, content: str) -> str:
         with open(filename, 'w', encoding='utf-8') as f:
             f.write(content)
         return f'{content} written to {filename}.'
     
     
     jack = Agent(abilities=[calculator], brain=model, name='Jack', personality=Personality.INQUISITIVE)
     tylor = Agent(abilities=[write_file], brain=model, name='Tylor', personality=Personality.PRUDENT)
     
     
     @agentic(jack)
     def agent1():
         return
     
     
     @agentic(tylor)
     def agent2():
         return
     
     
     if __name__ == '__main__':
         ceo = Agent(abilities=[agent1, agent2], brain=model, name='CEO', personality=Personality.INQUISITIVE)
         radius = '(10.01 * 10.36 * 3.33 / 2 * 16)'  # 2762.663904
         pi = 3.14159
         output_file = 'result.txt'
         request = f"Here is a sphere with radius of {radius} cm and pi here is {pi}, find the area and volume respectively then write the results into a file called '{output_file}'."
         result = ceo.assign(request).just_do_it()  # area = 95910378.2949379, volume = 88322713378.13666
         print(result)

     In multi-agent collaboration scenario, you can assign different personalities to each distinct agent. For example, in the aforementioned script, Jack's capability is to perform calculations. I want him to try more and explore more, so Jack's personality is set to Personality.INQUISITIVE. On the other hand, Taylor's capability is to create and write files. For operations involving interaction with the external file system, I want him to be more cautious, so Taylor's personality is set to Personality.PRUDENT.
