Claude Haiku 5.5, sold by Anthropic, became available on AWS as the fastest and most efficient model in the Claude 5.5 family. Designed for real-time experiences like voice agents and high-volume tasks such as document summarization, it reportedly costs about 75% less than its predecessor, Haiku 4.5, for most workloads. Unique features include effort controls allowing cost versus intelligence tuning.
AWS provides access via Amazon Bedrock, which maintains data residency within AWS infrastructure and adds managed features like Guardrails, or through Claude Platform on AWS, offering direct API access unified with AWS billing. These deployment options facilitate scalable AI agent workflows and cost-managed performance, enhancing integration flexibility.
