Claude Haiku 5.5 targets high-volume tasks
Anthropic’s Claude Haiku 5.5 targets quick, repeated work such as classification, summaries and database queries. It gives the Claude 5.5 family a smaller option for applications where response time and volume matter.
Smaller tasks get an effort control
The Haiku 5.5 release describes live customer support, browser work and coding subagents among its intended uses. It is also the first Haiku-class model with an adjustable effort setting, allowing developers to trade more processing for capability.
