Claude Haiku 5.5 is the smallest and fastest model in Anthropic’s current Claude family. It was released on October 7, 2026, and it is built for tasks where you need many quick answers at a very low price: sorting messages, tagging products, short replies, translations and simple agents.
How Haiku 5.5 pricing works
Haiku 5.5 is the only current Claude model with a price step based on prompt length. If the whole request is up to 100,000 tokens, you pay the low rate. If it is longer, the higher rate applies to every token in that request, not only to the part above the limit.
| Haiku 5.5, per 1M tokens | Up to 100K tokens | Above 100K tokens |
|---|---|---|
| Input | $0.10 | $0.50 |
| Output | $0.50 | $2.50 |
| Cache read | $0.01 | $0.05 |
| Batch input / output | $0.05 / $0.25 | $0.25 / $1.25 |
For comparison, the older Haiku 4.5 costs $1 for input and $5 for output. Anthropic says most Haiku requests are short, so the average saving compared with Haiku 4.5 is large. Haiku 4.5 is still available for apps that need it.
What Haiku 5.5 is good at
- Customer support bots that answer common questions in seconds.
- Sorting and tagging large lists: leads, reviews, emails and products.
- Short marketing texts in bulk, such as product descriptions and ad variants.
- Sub-agents inside a bigger AI agent, where a stronger model plans and Haiku does the simple steps.
When to choose a bigger model
Haiku is fast, but it is not the best at deep reasoning. For long strategy documents, complex code or careful analysis, Sonnet 5.5 at $2 and $10 or Opus 5.5 at $4 and $20 per million tokens will give better results. A common setup is to test the task on Haiku first and move up only if the quality is not good enough.
Can I use Haiku 5.5 without coding?
In the Claude apps you can usually pick a model from the menu, and Haiku is the lightest choice. Its real strength, however, is the API, where a developer or an automation tool such as Make or n8n sends thousands of small requests for a few cents.
