Verdict

When to choose each

Claude Haiku 5.5

Where it leads

  • Lower input and output prices, $0.10 and $0.50 vs $0.40 and $1.60 per 1M tokens
  • Higher GPQA Diamond score, 89.6% vs 65.8%
  • Higher FrontierMath Tiers 1-3 (v2) score, 75.1% vs 6.7%
  • Higher SimpleQA Verified score, 23.8% vs 12.7%
  • Longer responses, up to 128,000 vs 32,768 output tokens
  • Cheaper cached input, $0.01 vs $0.10 per 1M tokens
  • Batch pricing, $0.05 input and $0.25 output per 1M tokens

Best for

  • High-volume classification, extraction and routing under the 100,000-token line
  • Cost-sensitive fan-out steps where a frontier model is overkill

Watch out for

  • Priced by prompt length, and it is a cliff rather than a taper: a request whose prompt passes 100,000 tokens is billed at $0.50 input and $2.50 output for the whole request, five times the short rate
  • Cache reads and cache writes both count toward that 100,000-token measurement, so a large cached prefix can tip a request into the higher band on its own
  • It is the only current Claude model whose 1M window is not priced uniformly; every other 4.6-and-later model bills a 900k request at the same rate as a 9k one
