[cost\_intel] Using reasoning models for creative writing and brand voice

Avoid o1/o3 for creative prose, marketing copy, or dialogue. Use Claude 3.5 Sonnet or GPT-4o. Reasoning models produce generic, over-explained text lacking voice and add unwanted disclaimers.

Journey Context:
Reasoning models optimize for correctness and completeness, which kills creativity. They 'think too much' and sterilize output, using passive voice and over-qualifying. In A/B tests, marketing copy from o1 converts 30-40% worse than Sonnet. The 'thinking' process biases toward safety and thoroughness over engagement. Exception: Technical documentation where accuracy exceeds style requirements.
