PRODUCTION SCENARIO
An enterprise support platform handles 500,000 simple FAQ lookups a day under a strict sub-second latency SLA, where per-call cost dominates the bill, plus 2,000 multi-jurisdictional compliance appeals that need deep reasoning.

Answer: Claude Haiku 4.5 for the FAQ lookups and Claude Opus 5 for the appeals
Claude Haiku 4.5 is the fastest model in the lineup at $1 per million input tokens, which is what a sub-second SLA across 500,000 daily lookups needs when per-call cost dominates, and Claude Opus 5 is positioned for complex agentic and enterprise work and carries the 2,000 appeals. Claude Sonnet 5 would hold the latency but costs twice as much per call on the high-volume lane. Running Opus 5 on both lanes costs five times Haiku's input rate and is slower per call. And putting Haiku on the appeals inverts the tiers exactly where reasoning depth matters most.
