[cost\_intel] Models generating verbose conversational outputs when only short structured answers are needed

Set max\_tokens aggressively and use Structured Outputs \(JSON mode\) to constrain generation, forcing the model to skip preambles.

Journey Context:
Output tokens cost 3x input tokens \(for most providers\). Unconstrained models often add conversational filler like 'Sure, here is the JSON:'. This silently triples the cost per request. JSON mode forces the model to skip preambles and output only the required data.
