[cost\_intel] When do reasoning models produce worse creative output than instruct models?

Avoid o1/o3 for creative writing, marketing copy, or brainstorming. Reasoning models converge on safe, median outputs due to reward model optimization. GPT-4o produces more novel metaphors \(perplexity 8.2 vs o1's 6.1 on creative benchmarks\). Use 4o with temperature 0.9\+ for creative tasks; use o1 only for technical writing requiring logical rigor. Cost: 6x higher for worse creative output.

Journey Context:
The 'overthinking' failure mode: o1 second-guesses creative choices, flattening voice and tone. In A/B tests, marketing copy from o1 shows 15% lower engagement than 4o because it optimizes for 'factual correctness' in fiction. Exception: screenplay dialogue logic checks or plot hole detection, where reasoning improves coherence. The quality signature is 'blandness'—o1 scores lower on novelty metrics \(Distinct-1/2\) despite higher grammar scores.
