Can you please share the problem?

I don't really want it added to the training set, but eh. Here you go:

> Assume I have a 3D printer that's currently printing, and I pause the print. What expends more energy, keeping the hotend at some temperature above room temperature and heating it up the rest of the way when I want to use it, or turning it completely off and then heat it all the way when I need it? Is there an amount of time beyond which the answer varies?

All LLMs I've tried get it wrong because they assume that the hotend cools immediately when stopping the heating, but realize this when asked about it. Qwen didn't realize it, and gave the answer that 30 minutes of heating the hotend is better than turning it off and back on when needed.

What kind of answer do you expect? It all depends on the hotend shape and material, temperature differences, how fast air moves in the room, humidity of the air, etc.

Qwen3-32b did it pretty accurately it seems. Calculated heat loss over time going to ambient temp, offered to keep it at standby 100C for short breaks under 10 minutes. Shut down completely for longer breaks.

Ah! This problem was given to me by my father-in-law in the form of the operating pizza ovens in the midwest during winter. It's a neat, practical one.

Some calculation around heat loss and required heat expenditure to reheat per material or something?

don't worry, it is really trickly for training
