LlamaIndex is a data framework for your LLM application that allows you to work with private or domain-specific data and simplifies the interface between your data source and LLM. Developers can use LlamaIndex to build chatbots, applications, private set-ups, and Q&A over documents and web pages. The implemented features for LlamaIndex include Support Web Page Reader and Support Database Reader.

How to bring LlamaIndex Models to MindsDB

Before creating a model, you can create an ML engine for LlamaIndex using the CREATE ML_ENGINE statement and provide own OpenAI API key: 
CREATE ML_ENGINE llama_index
FROM llama_index
USING
    llama_index_api_key='your-api-key';
You can check the available engines with this command: 
SHOW ML_ENGINES;
Alternatively, you can use the default llama_index engine, if available. Please note that it is necessary to provide own OpenAI API key while creating the model. Next, we use the CREATE MODEL statement to create the LlamaIndex model in MindsDB. 
CREATE MODEL model_name
FROM datasource
    (SELECT * FROM table_name)
PREDICT column_to_be_predicted
USING 
  engine = 'llama_index', 
  index_class = 'vector_store_index',
  reader = 'reader_type',
  source_url_link = 'source_url_link',
  input_column = 'column_name',
  openai_api_key = 'your_openai_api_key';
Where:
NameDescription
engineIt defines the LlamaIndex engine.
index_classIt is used to define the type of vector store index used.
readerIt defines the type of reader (either data reader or webpage reader).
source_url_linkIt defines the URL link used to get the answers from.
input_columnIt defines the prompt to the model.
openai_api_keyIt is used to provide your OpenAI API key to gain access to the model.

​
Example

Let’s explore a usecase where you will be creating a question-answering model that retrieves answers from a webpage. OpenAI will be used as the LLM and Blackrock’s investment webpage will be used as the datasource. Use the CREATE MODEL syntax to create a model with Llamaindex. We use a table that contains questions to train the model. This data can be downloaded here and uploaded as a file to MindsDB. If you want to know how to upload a file, you can check out the documentation here. 
CREATE MODEL qa_blackrock
FROM files
    (SELECT * FROM about_blackrock)
PREDICT Answers
USING 
  engine = 'llama_index', 
  index_class = 'GPTVectorStoreIndex',
  reader = 'DFReader',
  source_url_link = 'https://www.blackrock.com/za/individual/about-us',
  input_column = 'Questions',
  openai_api_key = 'your_api_key';
Please visit our docs on the CREATE MODEL statement to learn more.
The status of the model can be verified that it has completed training successfully by using the DESCRIBE syntax. 
DESCRIBE qa_blackrock;
The model can be queried for a single prediction by providing it with a question. 
SELECT Questions, Answers
FROM qa_blackrock
WHERE Questions = 'What is the best long term investment with minimal risks for private investors?';
On execution you get:
