This notebook was originally published at filipmichalsky/SalesGPT by @FilipMichalsky.SalesGPT is context-aware, which means it can understand what section of a sales conversation it is in and act accordingly.As such, this agent can have a natural sales conversation with a prospect and behaves based on the conversation stage. Hence, this notebook demonstrates how we can use AI to automate sales development representatives activites, such as outbound sales calls. Additionally, the AI Sales agent has access to tools, which allow it to interact with other systems.Here, we show how the AI Sales Agent can use a Product Knowledge Base to speak about a particular's company offerings,


hence increasing relevance and reducing hallucinations.We leverage the langchain library in this implementation, specifically Custom Agent Configuration and are inspired by BabyAGI architecture .Import Libraries and Set Up Your Environmentâ€‹import osimport re# import your OpenAI keyOPENAI_API_KEY = "sk-xx"os.environ["OPENAI_API_KEY"] = OPENAI_API_KEYfrom typing import Dict, List, Any, Union, Callablefrom pydantic import BaseModel, Fieldfrom langchain import LLMChain, PromptTemplatefrom langchain.llms import BaseLLMfrom langchain.chains.base import Chainfrom langchain.chat_models import ChatOpenAIfrom langchain.agents import Tool, LLMSingleActionAgent, AgentExecutorfrom langchain.text_splitter import CharacterTextSplitterfrom langchain.embeddings.openai import OpenAIEmbeddingsfrom langchain.chains import RetrievalQAfrom langchain.vectorstores import Chromafrom langchain.llms import OpenAIfrom langchain.prompts.base import StringPromptTemplatefrom langchain.agents.agent import AgentOutputParserfrom langchain.agents.conversational.prompt import FORMAT_INSTRUCTIONSfrom langchain.schema import AgentAction, AgentFinish# install aditional dependencies# ! pip install chromadb openai tiktokenSalesGPT architectureâ€‹Seed the SalesGPT agentRun Sales Agent to decide what to do:a) Use a tool, such as look up Product Information in a Knowledge Baseb) Output a response to a user Run Sales Stage Recognition Agent to recognize which stage is the sales agent at and adjust their behaviour accordingly.Here is the schematic of the architecture:Architecture diagramâ€‹Sales conversation stages.â€‹The agent employs an assistant who keeps it in check as in what stage of the conversation it is in.

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.The original implementation: https://github.com/lightaime/camelProject website: https://www.camel-ai.org/Arxiv paper:

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


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 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):


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


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.    Input: None.            AI Assistant (Python Programmer):        Solution: We can visualize the stock data, short-term moving average, and long-term moving average using a line chart using the `plot()` function from pandas. We can use the following code to visualize the data:        ```    plt.figure(figsize=(12,6))    plt.plot(new_df.index, new_df['close'], label='Close')    plt.plot(new_df.index, new_df['short_ma'], label='Short MA')    plt.plot(new_df.index, new_df['long_ma'], label='Long MA')    plt.xlabel('Date')    plt.ylabel('Price')    plt.title('Stock Data with Moving Averages')    plt.legend()    plt.show()    ```        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.
