Advantages of Eden AI and Chainlit for AI Chatbot Development

AskYoda and Chainlit offer significant advantages for those looking to create and customize AI chatbots.

Chainlit, an open-source Python framework, provides the capability to develop Conversation AI interfaces with ease, allowing for customization through various providers.

On the other hand, AskYoda, developed by Eden AI, empowers users to craft and train AI chatbots using their specific data.

AskYoda’s integration with providers such as OpenAI, Cohere, and Google Cloud expands its functionality, addressing limitations by enabling seamless data integration and training in multiple programming languages.‍

How to build a custom chatbot using ChainLit?‍

Step 1. Prerequisites

💡 Make sure you have the following libraries installed: chainlit, requests, json, dotenv, os



import chainlit as cl 
import requests 
import json 
from dotenv 
import load_dotenv 
import os 
from typing import Optional 
from chainlit.types import ThreadDict 
from chainlit.input_widget import Select, Slider‍

Step 2. Decorator and Chat Settings

Chainlit works with decorators for handling interactions, so you will need to use it for each of the interaction you want to handle. Here’s an example decorator, followed by the function that will be triggered when a new message is posted.



@cl.on_message #The decorator 
async def main(message: cl.Message): 
    await cl.Avatar( 
        name="AskYoda", 
        path = "public/logo_light.png" 
        ).send()‍

You can also customize chat settings using cl.ChatSettings in the triggered function:



cl.ChatSettings( 
        [ 
            Select( 
               id="llm_provider", 
               label="LLM Provider", 
               values=["cohere", "amazon", "anthropic", "ai21labs", "openai", "google"], 
               initial_index = 4 
               ), 
             Select( 
               id="llm_model", 
               label="LLM Model", 
               values= [ 
                  "command", 
                  "command-light" 
)])‍

Step 3. Retrieve Chat Settings

You can retrieve the selected chat settings like this:



llm_model = cl.user_session.get("llm_model") 
llm_provider = cl.user_session.get("llm_provider")‍

Step 5. Make API Calls to AskYoda

Before making API calls, ensure you have the bearer token and project ID ready:



headers = {"Authorization": f"Bearer {Api_Key}"} 
url = f"https://api.edenai.run/v2/aiproducts/askyoda/{project_id}/ask_llm"‍

Then, gather all the necessary information and make the API call to Eden AI:



json_payload = {"query" : f"{message.content}", 

            "llm_provider" : llm_provider, 

            "history" : history, 

            "llm_model" : llm_model, 

            #Customize the personnality of your assistant 

            "personnality" : {}, 

            "chunks" : chunks 

            } 

    response = requests.post(url, json=json_payload, headers=headers) 

    result = json.loads(response.text) 

if 'result' in result: 
        a = str(result['result']) 
        history.append({"user": f"{message.content}", "assistant": f"{a}"}) 
        # Send a response back to the user 
        await cl.Message( 
              content=f"{result['result']}", author = 'AskYoda' 

        ).send() 
else: 
        await cl.Message( 
            content=f"Key 'result' not found in the response. : {result}", 
        ).send()‍
