Claude Haiku pricing: 4.5 vs 5.5 list rates
Buyer-intent searches for claude haiku pricing want Anthropic list $/MTok — and a way to turn that into cost per thousand CSV rows. Here is both.
Anthropic list prices
USD per 1M tokens. Haiku 5.5 short-tier matches GPT-6 Luna’s headline rate; the threshold where the higher tier starts is what flips long-prompt bills.
| Model | Prompt tier | Input | Output | Cache read | Cache write |
|---|---|---|---|---|---|
| Haiku 5.5 | ≤100K tokens | $0.10 | $0.50 | $0.01 | $0.125 |
| Haiku 5.5 | >100K tokens | $0.50 | $2.50 | $0.05 | $0.625 |
| Haiku 4.5 | Prior-gen list (ref.) | ~$0.80 | ~$4.00 | — | — |

What actually drives Haiku 5.5 batch cost
- Tokenizer — same text ≈30% more tokens than Haiku 4.5.
- Adaptive thinking — thinking tokens count toward
max_tokens; tiny limits can stop before a label. - System prompt length — repeated on every row; keep templates short or use prompt caching.
- Long-context tier — prompts >100K jump to $0.50 / $2.50 while Luna stays at short rates until ~272K.
Rough cost formula
cost ≈ (system_tokens + avg_row_tokens + output_tokens) × rows × $/MTok
For single-label classification, output is tiny — system + row input dominate. Validate on 20–50 gold rows before a full dump.
