. Claude Haiku 5.5 introduces adjustable effort settings for the first time in the Haiku line, allowing users to select Low, Medium, High, Xhigh, or Max settings depending on task complexity1
. Higher effort settings produce more intelligent responses but increase costs proportionally1
.Anthropic positions Haiku 5.5 as a supporting worker for Opus 5.5 and Sonnet 5.5 in agentic coding tasks
3
. A larger model might assemble a financial presentation while Haiku retrieves specific data points like revenue figures for individual slides, according to Alex Wang from financial AI company Rogo3
. "It's accurate enough that we'd trust it there and fast and cheap enough that we can run it a lot," Wang stated3
. The model pairs well with more capable siblings for complex projects requiring both sophisticated reasoning and rapid execution of routine subtasks2
