[cost\_intel] Reasoning models produce wooden prose in creative tasks

Avoid o1/o3 for marketing copy, fiction, or brand voice content; use Claude 3.5 Sonnet or 4o at 1/20th cost for higher style match and creativity scores.

Journey Context:
Reasoning models optimize for 'correctness' and factuality, which suppresses creative variance. On LMSYS Chatbot Arena, o1-preview ranks lower than Claude 3.5 Sonnet on 'creative writing' style control. The cost premium \(30x\) yields text that sounds like technical documentation. The cliff is at task type: if the output has no single correct answer, reasoning is harmful.
