[cost\_intel] Writing marketing copy requiring emotional resonance and distinct brand voice

Use Claude 3.5 Sonnet or GPT-4o; o1 produces wooden, over-analyzed prose that lacks voice. Instruct models win on human preference ratings for creativity by 2:1 margins

Journey Context:
Reasoning models decompose 'why this sentence works' and output generic, safe text optimized for logical coherence rather than emotional impact. The quality degradation signature for instruct models is repetitive phrasing; for reasoning models it's sterile, academic tone unsuitable for marketing. Cost difference is 10-20x for negative quality outcome. Use reasoning models only for copy requiring logical structure \(legal disclaimers, technical specs\), not creative generation.
