My favorite JIRAs are the ones I prevent from being worked on in the first place because they were unnecessary.
The ideal prompt is the one I don't fire because it would be a waste.
In an application with an LLM component, the ideal amount of inference is zero.
Ultimately this seems to lead to "the ideal amount of computers in the world is none" but for the sake of my continued employment let's let that one go by. :)
