[counterintuitive] Increasing temperature improves an LLM's reasoning capability on complex logic problems

Set temperature to 0 \(or very low\) for reasoning, math, and coding tasks; use higher temperatures only for creative generation.

Journey Context:
Developers conflate creativity with problem-solving ability. Raising temperature increases the probability of sampling lower-probability tokens. For deterministic tasks like math or code, the correct answer is usually a high-probability token. Increasing temperature just increases the chance of sampling a wrong token early in the generation, which derails the entire logical chain, leading to hallucinated logic rather than lateral thinking.
