Report #70791

[counterintuitive] Should I change both temperature and top\_p for diverse LLM outputs

Alter temperature OR top\_p, but not both. If using top\_p, leave temperature at 1.0 \(or default\). If using temperature, leave top\_p at 1.0.

Journey Context:
Developers often tweak both temperature and top\_p simultaneously to control output diversity. Because top\_p dynamically truncates the token pool based on cumulative probability, and temperature flattens/sharpens the distribution, combining them leads to unpredictable, often degenerate outputs \(e.g., infinite loops or incoherent text\). The API providers explicitly recommend against altering both.
