Which to pick
Pick **Claude Haiku 4.5** when latency or per-token cost is the constraint. At $0.80 in / $4 out per Mtok it is roughly nineteen times cheaper on input than Opus, and the response time difference is the gap between "feels like autocomplete" and "feels like waiting on a person."
Pick **Claude Opus 4.5** when the request requires multi-step planning, dense reasoning, or careful long-document synthesis. At $15 in / $75 out per Mtok it is the most expensive Anthropic tier — reach for it on the turns where a wrong answer is more costly than a slow one. Both ship the same 200k context window, so the trade-off is purely depth-of-reasoning vs cost.
