02 / OFFICIAL RATE CARD
Two tiers. One important threshold.
The threshold applies to prompt length for each request—not total monthly tokens.
| Per 1M tokens | Haiku 5.5 ≤100K | Haiku 5.5 >100K | Haiku 4.5 |
|---|---|---|---|
| Input | $0.10 | $0.50 | $1.00 |
| Output | $0.50 | $2.50 | $5.00 |
| Cache read | $0.01 | $0.05 | $0.10 |
| Cache write · 5 min | $0.125 | $0.625 | $1.25 |
Batch processing discount
Apply the Batch API switch in the calculator to model asynchronous workloads.
US-only inference multiplier
The optional US-only inference setting is priced at 1.1 times the global rate.
03 / CALCULATION METHOD
Know exactly what is being counted.
cost = input × input_rate + output × output_rate
+ cache_read × read_rate + cache_write × write_rateEvery token quantity is divided by one million. Monthly cost multiplies the result by requests per month. Batch and regional multipliers are applied last.
Important:
“90% cheaper” is a list-price comparison for requests up to 100K prompt tokens. Anthropic says Haiku 5.5 costs around 75% less on average; actual workloads depend on prompt length and tokenization.
04 / QUICK ANSWERS
Frequently asked questions
How much does Claude Haiku 5.5 cost?
On the Claude Platform, prompts up to 100K use $0.10 per million input tokens and $0.50 per million output tokens. Prompts over 100K use $0.50 input and $2.50 output.
Is Haiku 5.5 cheaper than Haiku 4.5?
At the published list prices, it is 90% cheaper for equivalent token counts in the short tier and 50% cheaper in the long tier. Actual task-level savings can differ.
What counts toward the 100K threshold?
This calculator treats normal input, cache reads and cache writes as prompt tokens for each individual request. Monthly token totals do not choose the tier.
What is the Haiku 5.5 model ID?
claude-haiku-5-5 on the Claude Platform. Check Anthropic’s current documentation before production use.
Does Haiku 5.5 support prompt caching?
Yes. The published cache-read and five-minute cache-write rates are included above. Other cache durations and providers may use different prices.
