Claude Haiku 4.5 is Anthropic’s fast, low-cost tier: $1 per million input tokens and $5
\nper million output, with a 200K context window and 64K maximum output. It is built for the
\nhigh-volume, latency-sensitive end of a workload \u2014 classification, extraction, routing,
\nshort-form generation, and the thousands of small calls an application makes that never
\nneeded a frontier model in the first place.<\/p>\n
Haiku’s real job in most production systems is to absorb traffic. A blended cost of about
\n$1.80 per million tokens means it can handle an order of magnitude more requests than an
\nOpus-tier model for the same money, which is why the standard architecture is Haiku in
\nfront, escalating to Sonnet or Opus only when a confidence check fails. The 200K context is
\nthe one place it is genuinely narrower than its siblings \u2014 the Sonnet and Opus tiers reach
\n1M \u2014 so document-scale work that needs the whole corpus in one prompt belongs elsewhere.
\nFor everything that fits, Haiku 4.5 is usually the correct default, and treating it as the
\nbaseline rather than the fallback is what keeps an AI feature’s unit economics viable.<\/p>","protected":false},"excerpt":{"rendered":"
