MindsDB provides the CREATE CHATBOT statement that lets you customize your chatbot with an AI model and a data source of your choice. Follow this tutorial to learn build a chatbot with a knowledge base.

The CREATE CHATBOT statement requires the following componenets:

  1. Chat app: A connection to a chat app, such as Slack or MS Teams.

  2. AI agent: An AI agent that comes with an AI model trained with the provided training data. Learn more about AI agents here.

Let’s go over getting all the components ready.

​
Chatbot Components

​
Chat App

Use the CREATE DATABASE statement to connect the chat app to MindsDB.

If you want to use Slack, follow this link to setup a Slack app, generate required tokens, and connect it to MindsDB.

If you want to use MS Teams, follow this link to generate required tokens and connect it to MindsDB.

​
AI Agent

Start by creating and deploying the model.

If you haven’t created a LangChain engine, use the CREATE ML_ENGINE statement, as explained here.

CREATE MODEL my_model
PREDICT answer
USING
    engine = 'langchain',
    input_column = 'question',
    openai_api_key = 'your-model-api-key', -- choose one of OpenAI (openai_api_key) or Anthropic (anthropic_api_key)
    model_name='gpt-4', -- optional model name from OpenAI or Anthropic
    mode = 'conversational',
    user_column = 'question' ,
    assistant_column = 'answer',
    max_tokens=100,
    temperature=0,
    verbose=True,
    prompt_template='Answer the user input in a helpful way';

Here is the command to check its status:

DESCRIBE my_model;

The status should read complete before proceeding.

Next step is to create one or more skills for an AI agent. Here we create a knowledge base and assign it as a skill.

In this example, let’s create an embedding model (you can choose one from OpenAI, Hugging Face, or LangChain) for the knowledge base.

CREATE ML_ENGINE openai_engine
FROM openai
USING
   openai_api_key = 'your-openai-api-key';

CREATE MODEL embedding_model
PREDICT embeddings
USING
   engine = 'openai_engine',
   mode='embedding',
   model_name='text-embedding-ada-002',
   question_column = 'content';

Now let’s create a knowledge base that uses this embedding model and the default storage vector database (that is, ChromaDB).

CREATE KNOWLEDGE BASE my_knowledge_base
USING
   model = embedding_model;

This is how you can insert data into the knowledge base and select it.

INSERT INTO my_knowledge_base (content)
VALUES ('I drink tea.');

SELECT * FROM my_knowledge_base;

Use this knowledge base to create a skill for an agent:

CREATE SKILL kb_skill
USING
    type = 'knowledge_base',
    source = 'my_knowledge_base', -- this must be created with CREATE KNOWLEDGE BASE
    description = 'My data';      -- data description to help the agent know when to use the knowledge base

This skill enables a model to answer questions about data from the knowledge base.

Now let’s create an AI agent using the above model and skill.

CREATE AGENT support_agent
USING
model = my_model,         -- this was created with CREATE MODEL
skills = ['kb_skill'];    -- this was created with CREATE SKILL

​
Create Chatbot

Once all the components are ready, let’s proceed to creating the chatbot.

CREATE CHATBOT my_chatbot
USING
   database = 'chat_app',     -- this parameters stores a connection to a chat app, like Slack or MS Teams
   agent = 'support_agent',   -- this parameter stores an agent name, which was create with CREATE AGENT
   is_running = true;            -- this parameter is optional and set to true by default, meaning that the chatbot is running

The database parameter stores connection to a chat app. And the agent parameter stores an AI agent created by passing a model and training data.

You can query all chatbot using this query:

SELECT * FROM chatbots;

Now you can go to Slack or MS Teams and chat with the chatbot created with MindsDB.
