Claude Haiku 5.5 puts everyday AI workloads in focus
Anthropic’s new small model targets frequent, repetitive tasks where speed and running costs matter.
What happened
Anthropic introduced Claude Haiku 5.5 on 7 October, positioning it for tasks such as summarisation, classification, database queries and customer support.
The company describes it as its fastest small model and says average running costs are around 75% below Haiku 4.5. That is Anthropic’s comparison, not a guaranteed saving for every application. Haiku 5.5 also introduces an adjustable effort setting within the Haiku family.
Our take
A smaller model can be a useful candidate for a well-defined, repeated job. The decision should depend on how often its answers need correction, alongside response speed and total cost.
What to test
Build a small set of realistic support messages with expected categories. Compare classification accuracy, difficult cases and the time needed for human review. Include ambiguous messages and examples in the languages your customers actually use before choosing a model.

Review time counts too. Negative results mean the example takes longer overall.
