This is awesome, congratulations. I'm glad to see some text-to-sql models being created. Shameless plug: I also just realized you used NSText2SQL[1] which itself contains my text-to-sql dataset, sql-create-context[2], so I'm honored. I used sqlglot pretty heavily on it as well.
Do you think a 3B model might also be in the future, or something small enough that can be loaded up in Transformers.js?
