What Claude Haiku 4.5 costs
| Rate | Per 1M tokens | Per 1K tokens | What it covers |
|---|---|---|---|
| Input | $1 | $0.001 | Every token you send: prompt, history, documents. |
| Output | $5 | $0.005 | Every token the model generates, including hidden reasoning tokens. |
| Cached input | $0.1 | $0.0001 | Input served from the provider’s prompt cache. |
| Cache write (5 minutes) | $1.25 | $0.00125 | Charged once, to put a prefix into the cache for the default five minutes. Estimates use this rate. |
| Cache write (1 hour) | $2 | $0.002 | The same write with a one-hour lifetime, for prompts reused less often than every five minutes. |
What that means in practice
The same three workloads are costed on every model page, so these numbers are directly comparable across the catalog. No prompt caching and no batch discount is assumed — the figures are what you pay before you optimize anything.
Support chatbot
2,500 six-turn conversations a day
$4,028 / month
$0.054 per conversation · $48,330 a year
An 800-token system prompt, 400-token questions and 900-token answers, over six turns — each turn re-sending everything before it.
Document summarizer
1,000 single-shot summaries a day
$486 / month
$0.016 per conversation · $5,832 a year
One 12,000-token document in, an 800-token summary out, no conversation history. The case where input dominates the bill.
Coding agent
200 twelve-turn sessions a day
$2,808 / month
$0.468 per conversation · $33,696 a year
A 3,000-token system prompt, 1,500-token instructions and 2,500-token responses over twelve turns. Long sessions are where the quadratic cost of re-sent history stops being theoretical.
