Anthropic launches Claude Haiku 5.5, the first Haiku model with effort controls, for high-volume, cost-sensitive tasks like summaries and classification (Anthropic)

Anthropic’s Claude Haiku 5.5 adds effort controls to its smallest model, giving enterprises a lower-cost option for high-volume work such as summarization and classification without giving up much capability. For CIOs, this signals that AI adoption can shift more routine workloads to cheaper models, improving unit economics and enabling broader deployment of AI across IT and business operations while reserving larger models for more complex tasks.
