Anthropic launches fast, low-cost AI Claude Haiku 5.5, cuts costs 75 percent

Anthropic has launched its low-cost AI model Claude Haiku 5.5, replacing Haiku 4.5 about a year after the last Haiku upgrade. The release extends a recent expansion of the Claude 5.5 lineup after earlier upgrades to Opus and Sonnet. The company said Haiku 5.5 is designed for high-volume, cost-sensitive work and is its fastest model. It also said operating costs are about 75 percent lower than the prior version and adjusted pricing for Sonnet 5.5.
