Rates by prompt length
Claude Haiku 5.5 bills each request by the length of its prompt, counting cache reads and cache writes. A prompt of over 100,000 tokens reprices the whole request at the higher rates below. A dash means no such rate is listed.
| Prompt length | Input / 1M | Output / 1M | Cached input / 1M | Cache write / 1M | Batch input / 1M | Batch output / 1M |
|---|---|---|---|---|---|---|
| 100,000 tokens or less | $0.10 | $0.50 | $0.01 | $0.125 | $0.05 | $0.25 |
| Over 100,000 tokens | $0.50 | $2.50 | $0.05 | $0.625 | $0.25 | $1.25 |
Pricing note: Priced by prompt length, per request. Standard (prompt of 100K tokens or less): $0.10 in / $0.01 cached / $0.50 out. Over 100K tokens (counting cache reads and writes), the whole request is billed at $0.50 in / $0.05 cached / $2.50 out. Batch is 50% off both tiers: $0.05 in / $0.25 out standard, $0.25 in / $1.25 out over 100K. Cache writes: 5-minute TTL $0.125/MTok standard and $0.625 over 100K; 1-hour TTL $0.20 standard and $1 over 100K. US-only inference (inference_geo: "us") is billed at 1.1x, including the over-100K prices.
What Claude Haiku 5.5 costs per month
Token volume split 3:1 between input and output, with no prompt caching. These figures assume prompts of 100,000 tokens or less (the standard rates). A prompt over that length bills the whole request at $0.50 per million input tokens and $2.50 per million output tokens, so long-prompt workloads cost more.
| Tokens per month | Input / output | Standard | Batch API |
|---|---|---|---|
| 1M | 750K / 250K | $0.20 | $0.10 |
| 10M | 7.5M / 2.5M | $2.00 | $1.00 |
| 100M | 75M / 25M | $20.00 | $10.00 |
