A specific example. Slangify: The Case for DSLs in LLM Workflows.

I've been working on DML, a Prolog-based DSL [0] used to define and orchestrate agents and LLM workflows. It's been quite fun, although - given the amazing capabilities of SOTA models - I am not so sure anymore how meaningful it will be to continue with this work. Anyways, the language and also supports DCGs, so it should allow for plenty of interesting ways to combine grammars, LLMs, agents etc.

Perhaps the research documented in "Combining Constraint Programming Reasoning with Large Language Model Predictions"[0] can provide meaning and/or options to your work.

I hope so, because the idea of Prolog leveraging language model offerings is very compelling.

Thank you! This looks very interesting!

glad you mention https://slangify.org … we are pulling together a set of tooling and example DSLs to make this kind of LLM-DSL combination super easy
