[synthesis] Why implementing standard API caching on LLM responses degrades AI product quality and user experience

Implement semantic caching that triggers only when the query intent and the context window state match above a high similarity threshold, and always invalidate cache on context window changes.

Journey Context:
Software caching relies on exact or near-exact key matching to save compute. LLM outputs are highly context-dependent. Caching a response to 'summarize this' will return the wrong summary if the underlying document changes. Traditional caching breaks the stateful, personalized nature of AI. Semantic caching with strict context-window hashing prevents returning stale or irrelevant generations while still saving compute, bridging the gap between deterministic infrastructure and probabilistic semantics.
