At my current company we're evaluating small models embedded directly in the web app to provide a natural language interface to the app without spending money on inference (and ideally avoid a ChatChipotle situation where people end up having free token going through our interface).
And needle is one of the most promising model due to its original architecture (but we still need to finish building the actual eval dataset before making out final call).
Thanks for considering needle. Keep in mind that you can also fine-tune the model to fit your use case more. I think this illustrates the intended deployment pretty well, where both computational resources and compute credits can both be issues for deployment.
