We've been working hard for the last year on building HeavyIQ, an LLM-powered plugin to the GPU-accelerated HeavyDB database, that allows users to ask natural language questions and get SQL, visualizations, and natural language answers back. The LLM itself is fine-tuned on tens of thousands of question and answer pairs, with a major focus around building the model’s proficiency at performing spatial and temporal joins.

You can try it for yourself on this live demo of 400M tweets and a handful of other datasets of interest: https://demo-heavyiq.heavy.ai/us_tweets/sql-notebook
