[cost\_intel] Tasks where frontier models remain irreplaceable despite 10x cost premium

Reserve GPT-4o/Claude 3.5 Sonnet for tasks requiring detection of implied meaning \(sarcasm, subtext, cultural nuance\), ambiguous intent classification, and high-stakes content moderation where false negatives carry legal/brand risk. Haiku/Flash will show 20-40% accuracy degradation on these 'vibe' tasks.

Journey Context:
Cost optimization drives teams to downgrade all tasks to smaller models, but this creates invisible failure modes on judgment-heavy tasks. The distinguishing characteristic is not task complexity but ambiguity tolerance: frontier models handle 'it depends' scenarios where context determines meaning. Example: distinguishing 'This product is sick' as positive \(slang\) vs negative \(illness\) requires cultural knowledge. Haiku defaults to literal interpretation. The economic calculation: if a false negative costs >$1000 \(legal settlement, brand crisis\), the $0.02 vs $0.20 per call difference is irrelevant. Quality degradation signature: increased false positives on ambiguous negatives \(over-censorship\) or missed subtle violations.
