CAMEL Role-Playing Autonomous Cooperative Agents#
This is a langchain implementation of paper: “CAMEL: Communicative Agents for “Mind” Exploration of Large Scale Language Model Society”.
Overview:


Overview:
The rapid advancement of conversational and chat-based language models has led to remarkable progress in complex task-solving. However, their success heavily relies on human input to guide the conversation, which can be challenging and time-consuming. This paper explores the potential of building scalable techniques to facilitate autonomous cooperation among communicative agents and provide insight into their “cognitive” processes. To address the challenges of achieving autonomous cooperation, we propose a novel communicative agent framework named role-playing. Our approach involves using inception prompting to guide chat agents toward task completion while maintaining consistency with human intentions. We showcase how role-playing can be used to generate conversational data for studying the behaviors and capabilities of chat agents, providing a valuable resource for investigating conversational language models. Our contributions include introducing a novel communicative agent framework, offering a scalable approach for studying the cooperative behaviors and capabilities of multi-agent systems, and open-sourcing our library to support research on communicative agents and beyond.

AI User (Stock Trader):
Instruction: Calculate the short-term and long-term moving averages for the stock data using the `ta.SMA()` function from ta-lib.
Input: The period for the short-term moving average and the period for the long-term moving average.
AI Assistant (Python Programmer):
Solution: We can calculate the short-term and long-term moving averages for the stock data using the `ta.SMA()` function from ta-lib. We need to pass the period for the short-term moving average and the period for the long-term moving average as arguments to this function. We can use the following code to calculate the short-term and long-term moving averages:
```
short_ma = ta.SMA(df['close'], timeperiod=short_period)


long_ma = ta.SMA(df['close'], timeperiod=long_period)
```
This will calculate the short-term and long-term moving averages for the stock data and store them in the `short_ma` and `long_ma` variables, respectively. Next request.
AI User (Stock Trader):
Instruction: Create a new DataFrame that combines the historical stock data with the short-term and long-term moving averages.
Input: None.
AI Assistant (Python Programmer):
Solution: We can create a new DataFrame that combines the historical stock data with the short-term and long-term moving averages using the `concat()` function from pandas. We need to pass the historical stock data, the short-term moving average, and the long-term moving average as arguments to this function. We can use the following code to create the new DataFrame:
```
new_df = pd.concat([df, short_ma, long_ma], axis=1)
new_df.columns = ['open', 'high', 'low', 'close', 'volume', 'short_ma', 'long_ma']
```
This will create a new DataFrame called `new_df` that combines the historical stock data with the short-term and long-term moving averages. The columns of the new DataFrame are named 'open', 'high', 'low', 'close', 'volume', 'short_ma', and 'long_ma'. Next request.

AI User (Stock Trader):
Instruction: Create a new column in the DataFrame that indicates when to buy or sell the stock based on the crossover of the short-term and long-term moving averages.
Input: None.
AI Assistant (Python Programmer):
Solution: We can create a new column in the DataFrame that indicates when to buy or sell the stock based on the crossover of the short-term and long-term moving averages. We can use the following code to create the new column:
```
new_df['signal'] = np.where(new_df['short_ma'] > new_df['long_ma'], 1, -1)
```
This will create a new column called 'signal' in the DataFrame that indicates when to buy or sell the stock based on the crossover of the short-term and long-term moving averages. If the short-term moving average is greater than the long-term moving average, the signal is 1 (buy), otherwise the signal is -1 (sell). Next request.
AI User (Stock Trader):
Instruction: Create a new column in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target.
Input: The stop loss and profit target as percentages.
AI Assistant (Python Programmer):
Solution: We can create a new column in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target. We need to pass the stop loss and profit target as percentages as arguments to this function. We can use the following code to create the new column:
```


```
stop_loss = stop_loss_percent / 100
profit_target = profit_target_percent / 100
new_df['pnl'] = 0.0
buy_price = 0.0
for i in range(1, len(new_df)):
    if new_df['signal'][i] == 1 and new_df['signal'][i-1] == -1:
        buy_price = new_df['close'][i]
    elif new_df['signal'][i] == -1 and new_df['signal'][i-1] == 1:
        sell_price = new_df['close'][i]
        if sell_price <= buy_price * (1 - stop_loss):
            new_df['pnl'][i] = -stop_loss
        elif sell_price >= buy_price * (1 + profit_target):
            new_df['pnl'][i] = profit_target
        else:
            new_df['pnl'][i] = (sell_price - buy_price) / buy_price
```


```
This will create a new column called 'pnl' in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target. The stop loss and profit target are calculated based on the stop_loss_percent and profit_target_percent variables, respectively. The buy and sell prices are stored in the buy_price and sell_price variables, respectively. If the sell price is less than or equal to the stop loss, the profit or loss is set to -stop_loss. If the sell price is greater than or equal to the profit target, the profit or loss is set to profit_target. Otherwise, the profit or loss is calculated as (sell_price - buy_price) / buy_price. Next request.
AI User (Stock Trader):
Instruction: Calculate the total profit or loss for all trades.
Input: None.
AI Assistant (Python Programmer):
Solution: We can calculate the total profit or loss for all trades by summing the values in the 'pnl' column of the DataFrame. We can use the following code to calculate the total profit or loss:
```
total_pnl = new_df['pnl'].sum()
```
This will calculate the total profit or loss for all trades and store it in the total_pnl variable. Next request.
AI User (Stock Trader):
Instruction: Visualize the stock data, short-term moving average, and long-term moving average using a line chart.

```
This will create a line chart that visualizes the stock data, short-term moving average, and long-term moving average. The x-axis represents the date and the y-axis represents the price. The chart also includes a legend that labels each line. Next request.
AI User (Stock Trader):
Instruction: Visualize the buy and sell signals using a scatter plot.
Input: None.
AI Assistant (Python Programmer):
Solution: We can visualize the buy and sell signals using a scatter plot using the `scatter()` function from matplotlib. We can use the following code to visualize the signals:
```
buy_signals = new_df[new_df['signal'] == 1]


sell_signals = new_df[new_df['signal'] == -1]
plt.figure(figsize=(12,6))
plt.scatter(buy_signals.index, buy_signals['close'], label='Buy', marker='^', color='green')
plt.scatter(sell_signals.index, sell_signals['close'], label='Sell', marker='v', color='red')

Main Loop
Two-Player Dungeons & Dragons#
In this notebook, we show how we can use concepts from CAMEL to simulate a role-playing game with a protagonist and a dungeon master. To simulate this game, we create an DialogueSimulator class that coordinates the dialogue between the two agents.
Import LangChain related modules#
from typing import List, Dict
from langchain.chat_models import ChatOpenAI
from langchain.schema import (
    AIMessage,
    HumanMessage,
    SystemMessage,
    BaseMessage,
)
DialogueAgent class#
The DialogueAgent class is a simple wrapper around the ChatOpenAI model that stores the message history from the dialogue_agent’s point of view by simply concatenating the messages as strings.
It exposes two methods:
send(): applies the chatmodel to the message history and returns the message string
receive(name, message): adds the message spoken by name to message history
class DialogueAgent():
    def __init__(
        self,
        name,
        system_message: SystemMessage,
        model: ChatOpenAI,
    ) -> None:
        self.name = name
        self.system_message = system_message
        self.model = model
        self.message_history = f"""Here is the conversation so far.
        """
        self.prefix = f'\n{self.name}:'

    def send(self) -> str:


def send(self) -> str:
        """
        Applies the chatmodel to the message history
        and returns the message string
        """
        message = self.model(
            [self.system_message,
             HumanMessage(content=self.message_history+self.prefix)])
        return message.content

    def receive(self, name: str, message: str) -> None:
        """
        Concatenates {message} spoken by {name} into message history
        """
        self.message_history += f'\n{name}: {message}'
DialogueSimulator class#
The DialogueSimulator class takes a list of agents. At each step, it performs the following:
Select the next speaker
Calls the next speaker to send a message
Broadcasts the message to all other agents
Update the step counter.
The selection of the next speaker can be implemented as any function, but in this case we simply loop through the agents.
class DialogueSimulator():

    def __init__(self, agents: List[DialogueAgent]):
        self.agents = agents
        self._step = 0

    def reset(self, name: str, message: str):
        """
        Initiates the conversation with a {message} from {name}
        """
        for agent in self.agents:
            agent.receive(name, message)

    def select_next_speaker(self, step: int) -> int:
        idx = (step + 1) % len(self.agents)
        return idx

    def step(self) -> tuple[str, str]:
        # 1. choose the next speaker
        speaker = self.agents[self.select_next_speaker(self._step)]

        # 2. next speaker sends message


# 2. next speaker sends message
        message = speaker.send()

        # 3. everyone receives message
        for receiver in self.agents:
            receiver.receive(speaker.name, message)

        # 4. increment time
        self._step += 1

        return speaker.name, message

(Dungeon Master): Harry Potter, you must journey to the hidden cave where one of Voldemort's horcruxes resides. The cave is guarded by enchanted creatures and curses that can only be lifted by a unique magical potion. Use your wit and skill to obtain the ingredients, brew the potion, and retrieve the horcrux before time runs out.
(Harry Potter): I take a deep breath and focus on the task at hand. I search my bag for any potions or ingredients that may be useful in brewing the unique magical potion. If I don't have any, I will search the surrounding area for any plants or herbs that may be useful. Once I have all the necessary ingredients, I will brew the potion and use it to lift the curses and defeat any enchanted creatures guarding the horcrux. It won't be easy, but I am determined to succeed.
It is your turn, Dungeon Master.


It is your turn, Dungeon Master.
(Dungeon Master): As you search your bag, you find a few useful potions and ingredients that will aid you in your quest. You also spot some herbs growing nearby that you recognize as key ingredients for the unique magical potion. You gather everything you need and begin brewing the potion. It takes some time, but you manage to create the perfect mixture. As you approach the cave, you drink the potion and feel a surge of power coursing through your veins. The curses and creatures guarding the horcrux are no match for you now. You retrieve the horcrux and add it to your collection. Well done, Harry Potter. But beware, the next horcrux will be even more challenging to obtain.
It is your turn, Harry Potter.
(Harry Potter): I take a moment to catch my breath and assess my next move. I know that the next horcrux will be even more difficult to obtain, but I am ready for the challenge. I consult my map and try to determine the location of the next horcrux. Once I have a general idea, I set off on foot, keeping my wand at the ready in case of any unexpected obstacles. I am determined to find and destroy all of Voldemort's horcruxes, no matter what it takes.
It is your turn, Dungeon Master.


It is your turn, Dungeon Master.
(Dungeon Master): As you consult your map, you notice that the next horcrux is located in a heavily guarded fortress. The fortress is surrounded by a moat filled with dangerous creatures and the entrance is protected by powerful spells. You will need to come up with a plan to get past the guards and break through the spells. As you approach the fortress, you notice a group of Death Eaters patrolling the perimeter. What do you do, Harry Potter?
It is your turn, Harry Potter.
(Harry Potter): I take cover behind a nearby tree and observe the Death Eaters' movements. I try to determine their patrol patterns and identify any weaknesses in their defenses. Once I have a plan, I use my invisibility cloak to sneak past them and make my way to the fortress entrance. I use my knowledge of spells to try and break through the protective enchantments. If that doesn't work, I will try to find another way in, perhaps through a secret passage or hidden entrance. I won't let anything stop me from finding and destroying the next horcrux.
It is your turn, Dungeon Master.


It is your turn, Dungeon Master.
(Dungeon Master): As you observe the Death Eaters, you notice that they have a predictable patrol pattern. You wait for the right moment and use your invisibility cloak to sneak past them undetected. You make your way to the fortress entrance and try to break through the protective enchantments, but they prove to be too strong. You search for another way in and eventually find a hidden entrance that leads you to the horcrux. However, as you reach for it, you trigger a trap that sets off an alarm and alerts the Death Eaters to your presence. You must act quickly to escape before they catch you.

Multi-Player Dungeons & Dragons#
This notebook shows how the DialogueAgent and DialogueSimulator class make it easy to extend the Two-Player Dungeons & Dragons example to multiple players.
The main difference between simulating two players and multiple players is in revising the schedule for when each agent speaks
To this end, we augment DialogueSimulator to take in a custom function that determines the schedule of which agent speaks. In the example below, each character speaks in round-robin fashion, with the storyteller interleaved between each player.
Import LangChain related modules#
from typing import List, Dict, Callable
from langchain.chat_models import ChatOpenAI
from langchain.schema import (
    AIMessage,
    HumanMessage,
    SystemMessage,
    BaseMessage,
)
DialogueAgent class#
The DialogueAgent class is a simple wrapper around the ChatOpenAI model that stores the message history from the dialogue_agent’s point of view by simply concatenating the messages as strings.
It exposes two methods:
send(): applies the chatmodel to the message history and returns the message string
receive(name, message): adds the message spoken by name to message history
class DialogueAgent():
    def __init__(
        self,
        name,
        system_message: SystemMessage,
        model: ChatOpenAI,
    ) -> None:
        self.name = name
        self.system_message = system_message


self.name = name
        self.system_message = system_message
        self.model = model
        self.message_history = f"""Here is the conversation so far.
        """
        self.prefix = f'\n{self.name}:'

    def send(self) -> str:
        """
        Applies the chatmodel to the message history
        and returns the message string
        """
        message = self.model(
            [self.system_message,
             HumanMessage(content=self.message_history+self.prefix)])
        return message.content

    def receive(self, name: str, message: str) -> None:
        """
        Concatenates {message} spoken by {name} into message history
        """
        self.message_history += f'\n{name}: {message}'
DialogueSimulator class#
The DialogueSimulator class takes a list of agents. At each step, it performs the following:
Select the next speaker
Calls the next speaker to send a message
Broadcasts the message to all other agents
Update the step counter.
The selection of the next speaker can be implemented as any function, but in this case we simply loop through the agents.
class DialogueSimulator():

    def __init__(
        self,
        agents: List[DialogueAgent],
        selection_function: Callable[[int, List[DialogueAgent]], int]
    ) -> None:
        self.agents = agents
        self._step = 0
        self.select_next_speaker = selection_function

    def reset(self, name: str, message: str):
        """
        Initiates the conversation with a {message} from {name}
        """
        for agent in self.agents:


"""
        for agent in self.agents:
            agent.receive(name, message)

        # increment time
        self._step += 1

    def step(self) -> tuple[str, str]:
        # 1. choose the next speaker
        speaker_idx = self.select_next_speaker(self._step, self.agents)
        speaker = self.agents[speaker_idx]

        # 2. next speaker sends message
        message = speaker.send()

        # 3. everyone receives message
        for receiver in self.agents:
            receiver.receive(speaker.name, message)

        # 4. increment time

(Dungeon Master): You have discovered that one of Voldemort's horcruxes is hidden deep in the Forbidden Forest. You must navigate the dangerous terrain, avoid the creatures lurking within, and find the horcrux before the full moon rises, unleashing a pack of hungry werewolves. Remember, time is of the essence!


(Harry Potter): I take out my wand and cast a Lumos spell to light our way through the dark forest. We need to move quickly and quietly to avoid any unwanted attention from the creatures. Ron, Hermione, and I will lead the way while Argus Filch keeps watch behind us. Let's go!
(Dungeon Master): As you make your way through the forest, you hear the rustling of leaves and the snapping of twigs. Suddenly, a group of acromantulas, giant spiders, appear in front of you, blocking your path. What do you do?
(Ron Weasley): I quickly cast a spell to create a wall of fire between us and the acromantulas. Hopefully, the flames will deter them from attacking us. We need to keep moving forward and find that horcrux before it's too late.
(Dungeon Master): The acromantulas hiss and retreat from the wall of fire, allowing you to pass. As you continue deeper into the forest, you come across a clearing with a small pond. In the center of the pond, you see a glowing object. It must be the horcrux! But how do you get to it? What do you do?
(Hermione Granger): I take out my wand and cast a spell to conjure a small boat. We can use it to reach the center of the pond and retrieve the horcrux. But we need to be careful, there could be traps or other obstacles in our way. Ron, Harry, let's row the boat while Argus Filch keeps watch from the shore.


(Dungeon Master): As you row towards the center of the pond, you hear a loud hissing sound. Suddenly, a giant serpent emerges from the water, blocking your path. It looks angry and ready to attack. What do you do?
(Argus Filch): I take out my crossbow and aim it at the serpent. I may not be a wizard, but I know how to handle a weapon. I'll shoot it if it comes any closer. We can't let this serpent stop us from getting that horcrux.
(Dungeon Master): The serpent lunges towards the boat, but Argus Filch's crossbow bolt hits it in the head, causing it to retreat back into the water. You reach the center of the pond and retrieve the glowing object, which turns out to be a locket. Congratulations, you have found one of Voldemort's horcruxes! But there are still six more to find. What challenges will you face next?
(Harry Potter): We need to regroup and figure out our next move. We should head back to Hogwarts and consult with Professor Dumbledore's portrait. He may have some insight on where the other horcruxes could be hidden. We can't waste any time, Voldemort is getting stronger every day. Let's go!
(Dungeon Master): As you make your way back to Hogwarts, you hear a loud roar coming from the Forbidden Forest. It sounds like a werewolf. You must hurry before it catches up to you. You arrive at Dumbledore's office and he tells you that the next horcrux is hidden in a dangerous location. Are you ready for the next challenge?


(Ron Weasley): I'm always ready for a challenge! What's the location and what do we need to do to get there? We can't let Voldemort win, we have to find all of the horcruxes and destroy them. Let's do this!
(Dungeon Master): Dumbledore tells you that the next horcrux is hidden in the depths of Gringotts Bank. You must break into the bank, navigate its treacherous security measures, and find the horcrux before the goblins catch you. Are you ready to face the challenge of a lifetime? The fate of the wizarding world rests in your hands.
(Hermione Granger): I suggest we do some research on Gringotts Bank and its security measures before we attempt to break in. We need to be prepared and have a solid plan in place. We can also gather any necessary tools or potions that may help us along the way. Let's not rush into this blindly.
(Dungeon Master): As you research and plan your break-in to Gringotts Bank, you discover that the bank is heavily guarded by goblins, dragons, and other dangerous creatures. You'll need to be stealthy and quick to avoid detection. Are you ready to put your plan into action and face the dangers that await you? The clock is ticking, Voldemort's power grows stronger with each passing day.


(Argus Filch): I'll make sure to keep watch outside the bank while you all go in. I may not be able to help with the magic, but I can make sure no one interferes with our mission. We can't let anyone stop us from finding that horcrux and defeating Voldemort. Let's go!
(Dungeon Master): As you approach Gringotts Bank, you see the imposing structure looming before you. You sneak past the guards and make your way inside, navigating the twisting corridors and avoiding the traps set to catch intruders. Finally, you reach the vault where the horcrux is hidden. But it's guarded by a fierce dragon. What do you do?
(Harry Potter): I remember the time when I faced a dragon during the Triwizard Tournament. I take out my wand and cast a spell to distract the dragon while Ron and Hermione retrieve the horcrux. We need to work together and be quick. Time is running out and we can't afford to fail.
(Dungeon Master): The dragon roars and breathes fire, but Harry's spell distracts it long enough for Ron and Hermione to retrieve the horcrux. You make your way out of Gringotts Bank, but the goblins are hot on your trail. You must escape before they catch you. Congratulations, you have found another horcrux. But there are still five more to go. What challenges will you face next?


(Ron Weasley): We need to regroup and figure out our next move. We should consult with Professor Dumbledore's portrait again and see if he has any information on the next horcrux. We also need to be prepared for whatever challenges come our way. Voldemort won't make it easy for us, but we can't give up. Let's go!
(Dungeon Master): As you make your way back to Hogwarts, you hear a loud explosion coming from the direction of Hogsmeade. You arrive to find that Death Eaters have attacked the village and are wreaking havoc. You must fight off the Death Eaters and protect the innocent villagers. Are you ready to face this unexpected challenge and defend the wizarding world? The fate of both muggles and wizards rests in your hands.

BabyAGI User Guide#
This notebook demonstrates how to implement BabyAGI by Yohei Nakajima. BabyAGI is an AI agent that can generate and pretend to execute tasks based on a given objective.
This guide will help you understand the components to create your own recursive agents.
Although BabyAGI uses specific vectorstores/model providers (Pinecone, OpenAI), one of the benefits of implementing it with LangChain is that you can easily swap those out for different options. In this implementation we use a FAISS vectorstore (because it runs locally and is free).
Install and Import Required Modules#
import os
from collections import deque
from typing import Dict, List, Optional, Any
from langchain import LLMChain, OpenAI, PromptTemplate
from langchain.embeddings import OpenAIEmbeddings
from langchain.llms import BaseLLM
from langchain.vectorstores.base import VectorStore
from pydantic import BaseModel, Field
from langchain.chains.base import Chain
from langchain.experimental import BabyAGI
Connect to the Vector Store#
Depending on what vectorstore you use, this step may look different.
from langchain.vectorstores import FAISS
from langchain.docstore import InMemoryDocstore
# Define your embedding model
embeddings_model = OpenAIEmbeddings()
# Initialize the vectorstore as empty
import faiss
embedding_size = 1536
index = faiss.IndexFlatL2(embedding_size)


index = faiss.IndexFlatL2(embedding_size)
vectorstore = FAISS(embeddings_model.embed_query, index, InMemoryDocstore({}), {})
Run the BabyAGI#
Now it’s time to create the BabyAGI controller and watch it try to accomplish your objective.
OBJECTIVE = "Write a weather report for SF today"
llm = OpenAI(temperature=0)
# Logging of LLMChains
verbose = False
# If None, will keep on going forever
max_iterations: Optional[int] = 3
baby_agi = BabyAGI.from_llm(
    llm=llm, vectorstore=vectorstore, verbose=verbose, max_iterations=max_iterations
)

Thought: The CSV file has already been read and saved into a pandas dataframe called `df`. Hence, I can simply display the data by printing the whole dataframe. Since `df.head()` returns the first 5 rows, I can use that to showcase the contents.
Action: python_repl_ast
Action Input: print(df.head())   Year                               Name Country     Time
0  2022                       Evans Chebet   Kenya  2:06:51

3  2019                   Lawrence Cherono   Kenya  2:07:57
4  2018                      Yuki Kawauchi   Japan  2:15:58
Observation: None


4  2018                      Yuki Kawauchi   Japan  2:15:58
Observation: None
Thought:I used the wrong tool to perform the action. I should have used the given data and not interacted with the Python shell. I can now provide the displayed data as the answer since the information in the printed dataframe would look like a table when typed as text.
