Claude Haiku 5.5 pricing
It is tied for the cheapest of 37 current text models priced per 1M input tokens.
Independent benchmark results
Scores come from independent evaluators that ran the model themselves, pinned to a dated snapshot. Rank is among current models in the same snapshot. Anthropic's own launch figures are listed under strengths with the publisher named, because they are not measured the same way.

Strengths, cautions and best uses
Strengths
- The cheapest model in this catalogue at $0.10 per million input and $0.50 per million output for prompts up to 100,000 tokens
- Carries the full 1M-token context window and a 128,000-token output cap, which earlier Haiku releases did not
- Cache reads at $0.01 per million make high-volume classification and routing nearly free on the input side
Cautions
- Priced by prompt length, and it is a cliff rather than a taper: a request whose prompt passes 100,000 tokens is billed at $0.50 input and $2.50 output for the whole request, five times the short rate
- Cache reads and cache writes both count toward that 100,000-token measurement, so a large cached prefix can tip a request into the higher band on its own
- It is the only current Claude model whose 1M window is not priced uniformly; every other 4.6-and-later model bills a 900k request at the same rate as a 9k one
Best for
- High-volume classification, extraction and routing under the 100,000-token line
- Cost-sensitive fan-out steps where a frontier model is overkill
