Temperature controls how random or creative the AI is. Temperature=0: deterministic, always picks most likely word (same input = same output). Temperature=1: creative, picks from many options (different outputs each time). Scale: 0.0 to 2.0, default usually 0.7-1.0. Low temperature (0-0.3) for facts, code, consistent outputs. High temperature (0.7-1.5) for creative writing, brainstorming, variety. Single most important parameter to tune.
Use low temperature (0-0.3) for: factual tasks, code generation, data extraction, consistent outputs, customer support. Use high temperature (0.7-1.5) for: creative writing, brainstorming, marketing copy, when you want variety. Start at 0.7 (default), adjust based on results. Temperature=0 for production systems where consistency matters. Temperature=1+ for idea generation.
