This is an interactive demo of Binder based on GPT3 Codex.
You can input a question about the table (maybe requiring external knowledge/functionality), and a Binder program will be generated and executed to derive the output answer.

*Note:* Codex has query limits for openai keys, thus it may be slow in generation/execution when (high) concurrent requests occur.
We are trying to make the demo faster and more robust, please let us know if you have any feedback!
