[cost\_intel] When o1 underperforms GPT-4o on simple creative writing tasks \(the reasoning tax\)

Avoid o1 for tasks requiring stylistic creativity, humor, or conversational tone \(e.g., writing marketing copy, dialogue for games\). o1 tends toward over-formal, verbose, 'robotic' output due to its RL training on correctness signals. Use GPT-4o for creative generation; reserve o1 for editing/verification if needed.

Journey Context:
Teams try o1 for 'write a funny product description' and get back a 5-paragraph essay with bullet points. The RLHF for o1 optimized for correctness on math/code, not for humor or emotional resonance. o1 is more literal. For creative tasks, 4o is actually better \(or at least 10x faster and cheaper for same quality\). The signature is: if the evaluation metric is 'is this funny/engaging' \(subjective\), avoid o1. If it's 'is this logically consistent' \(objective\), use o1.
