Prefect is also a non-DAG based workflow engine that has very similar functionality to what is outlined here; they have built a few tools in the AI space (marvin and controlflow iirc)

Are you familiar with https://github.com/PrefectHQ/marvin? This looks very similar

Yes, similar ideas. Marvin [asks the LLM to mimic the python function](https://github.com/PrefectHQ/marvin/blob/f37ad5b15e2e77dd998...), whereas in magentic the function signature just represents the inputs/outputs to the prompt-template/LLM, so the LLM “doesn’t know” that it is pretending to be a python function - you specify all the prompts.

(Completely off-topic, but oh how I wish HN supported markdown)
