Anthropic has expanded its Claude 5.5 lineup with Haiku 5.5, a cost-optimized model priced at roughly one-quarter of its predecessor to target high-volume summarization and subagent workflows.

This release underscores a competitive shift toward offering specialized, cheaper models for specific operational tiers while maintaining superior performance on complex reasoning benchmarks.
