[cost\_intel] Paying reasoning-model prices for open-ended creative writing, design critique, or subjective advice

Use cheap instruct models for creative generation, style transfer, brainstorming, and subjective critique. Reasoning models produce longer, more verbose outputs without reliable quality gains when there is no automated verifier.

Journey Context:
Reasoning models are trained with reinforcement learning on verifiable rewards: correct math answers, passing tests, rule-based outcomes. DeepSeek-R1's breakthrough explicitly relied on rule-based rewards for deterministic ground-truth answers. Creative writing, marketing copy, design critique, and humor lack such verifiers. Extra chain-of-thought can make output more verbose and over-engineered without improving subjective quality. The cost difference is 10-40x for no measurable gain. Use instruct models with good prompts and evaluate against human preferences or downstream metrics. The signature of waste is a reasoning model generating elaborate justifications for stylistic choices.
