[cost\_intel] When is GPT-4o/Claude 3.5 Sonnet actually required vs. Gemini Flash or Haiku?

Reserve frontier models \(GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro\) exclusively for tasks requiring 'vibe' alignment—subjective judgment of tone, creativity, or cultural nuance where human raters show <80% inter-annotator agreement. For all objective tasks \(classification, extraction, math\), mid-tier models achieve >95% of frontier performance at 10-50x lower cost.

Journey Context:
The 'uncanny valley' of model capability isn't gradual. There's a discrete jump in 'taste' and subjective coherence that smaller models miss. Examples: creative writing with specific stylistic constraints, evaluating marketing copy for brand voice, or handling ambiguous customer service queries requiring emotional intelligence. Attempting to force mid-tier models to do this via complex prompting \(chain-of-thought, multi-shot\) increases latency and cost beyond simply using the frontier model once. The cost curve is non-convex here.
