This is a basic text to SQL tool that allows you to query datasets on Huggingface Hub.
It is built with [DuckDB](https://duckdb.org/), [Huggingface's Inference API](https://huggingface.co./docs/api-inference/index), and [LLama 3.1 70B](https://huggingface.co./meta-llama/Meta-Llama-3.1-70B-Instruct).
Also, it uses the [dataset-server API](https://redocly.github.io/redoc/?url=https://datasets-server.huggingface.co/openapi.json#operation/isValidDataset).
