What have we built?

A 1.3 bn SQL model that outperforms most SQL expert models and chatgpt on popular benchmarks. This is a distilled model built on the deepseek base model. Please refer to https://huggingface.co/PipableAI/pip-library-etl-1.3b for our state of the art model.

How we built it?

We used softmax cross entropy and a modified form of policy grad along with Q loss, optimized in an EM set up. Loss behaviour in the set up mentioned above -

Benchmarking :

For benchmarking purposes we are using Semantic Evaluation for Text-to-SQL with Distilled Test Suites, an officially accepted evaluation framework for Spider, SParC, and CoSQL which was proposed by a research team of Yale and Berkeley. The benchmark contains 2200 test data points Here is the link to run the evaluation:

Test Suite SQL Eval

gpt-3.5 58.8 44.7 31.0 28.4

We have also benchmarked it on defog eval. It contains 200 test data points handpicked by defog team. Here is the link to it:

Questions

What are the email address, town and county of the customers who are of the least common gender?

SELECT email_address ,  town_city ,  county FROM customers GROUP BY gender_code ORDER BY count(*) ASC LIMIT 1

What are the product price and the product size of the products whose price is above average?

SELECT product_price ,  product_size FROM products WHERE product_price  > (SELECT avg(product_price) FROM products)

Which customers did not make any orders? List the first name, middle initial and last name.

SELECT T1.customer_first_name ,  T1.customer_middle_initial ,  T1.customer_last_name FROM Customers AS T1 WHERE T1.customer_id NOT IN (SELECT T2.customer_id FROM Orders AS T2)
