Install

pip install from github:

Getting Started

Let's create a simple assistant that can be accessed via Telegram. First, you'll need to create a new Telegram bot and get the API token. You can do this by following the instructions in the Telegram documentation.

This example uses OpenAI's GPT-4o model to create a simple assistant that can help users buy Bitcoins. To use the OpenAI API, you'll need to sign up for an API key on the OpenAI website.

Configure Environment Variables

Make sure to set the OPENAI_API_KEY environment variable with your OpenAI API key:

export OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>

Then you can create a new Python script with the following code, don't forget to replace <YOUR_TELEGRAM_TOKEN> with the token you received from Telegram:

# Import Cel.ai modules
import os
from cel.connectors.telegram import TelegramConnector
from cel.gateway.message_gateway import MessageGateway
from cel.assistants.macaw.macaw_assistant import MacawAssistant
from cel.prompt.prompt_template import PromptTemplate


# Setup prompt
prompt = """You are an AI assistant. Called Celia. You can help a user to buy Bitcoins."""
prompt_template = PromptTemplate(prompt)

# Create the assistant based on the Macaw Assistant
# Macaw is a Langchain-based assistant that can be 
# used to create a wide variety of assistants
ast = MacawAssistant(prompt=prompt_template)

gateway = MessageGateway(
    assistant=ast,
    host="127.0.0.1", port=5004,
)

# For this example, we will use the Telegram connector
conn = TelegramConnector(
    token="<YOUR_TELEGRAM_TOKEN>"
)
                         
# Register the connector with the gateway
gateway.register_connector(conn)

# Then start the gateway and begin processing messages
# with ngrok enabled Cel.ai will automatically create a 
# public URL for the assistant.
gateway.run(enable_ngrok=True)
