About Claude Haiku 4.5 pricing

Claude Haiku 4.5 is Anthropic’s small, low-cost model built for high-volume, latency-sensitive tasks. It is billed per token: $1.00 for every million tokens you send and $5.00 for every million tokens it generates, so output costs 5× as much as input.

For a typical request of 1,000 input and 500 output tokens, Claude Haiku 4.5 costs about $0.0035 — the 5th-cheapest of the 14 models we track. One million input tokens is roughly 2,000 pages of English prose.

With Anthropic’s batch API (50% off, results within 24 hours) the rate drops to $0.50 input and $2.50 output per million tokens.
