[gotcha] Same question gets different answers each time, destroying user confidence in AI reliability

Cache responses for identical prompts within a session. Use seed parameters where available for reproducibility in deterministic contexts. Clearly communicate when users should expect variation \(creative tasks\) vs consistency \(factual queries\).

Journey Context:
Users develop a mental model where asking the same question should yield the same answer — this is how every other tool they have ever used works. When an LLM gives different answers to the same question, users don't think 'this is a feature of probabilistic models,' they think 'this tool is unreliable and I cannot trust any of its answers.' This is especially damaging when the answers contradict each other on factual questions. The fix isn't to make everything deterministic \(that would sacrifice the creative variation that makes LLMs useful\), but to be deterministic where users expect it. Within a single session, cache identical queries. For factual lookups, use lower temperature or seed parameters. For creative tasks, make it clear that variation is intentional. The key insight is that user expectations of determinism are contextual — they want the same answer for 'what is 2\+2' but different answers for 'write me a poem.' You must match the determinism to the intent.
