Claude Haiku 4.5 pricing and token costs
Claude Haiku 4.5 is a Anthropic model with a 200,000-token context window. Rates below are per million tokens, and are the ones in effect today.
In practice
At $1 per million input it is the cheapest Anthropic option, but its 200,000-token window is a fifth of what Opus 5 and Sonnet 5 accept — the window, not the price, is what usually rules it in or out. It is also the only Claude model here still on the claude-legacy tokenizer rather than claude-4-7, so its token estimates are derived differently from its siblings' even for identical text. Output is five times input, matching the rest of the Anthropic line.

Figures come from Anthropic’s published list prices and are checked against every article on this site that quotes them at build time. They are still estimates of what a request costs — verify against your own billing before committing to them. See the methodology page for how these numbers are actually calculated.
