banks is a side project by my colleague Massi. We work on the open source NLP framework Haystack together (https://github.com/deepset-ai/haystack) and prompt templating is obviously a 'hot' topic and it's something to design these types of projects around. Massi had this concept in mind to use Jinja (or any other templating language for that matter) as the basis, and clearly decided to take it for a spin. I personally am in love with this style of prompt templating and think it makes the whole process insanely flexible and easy to read. Wanted to share it here to see what others think. Hope you enjoy.
