Claude Haiku 5.5 Lands on AWS Bedrock at 75% Lower Cost With Effort Controls
3 articles · Updated · AWS Blog · Oct 13
Summary
Claude Haiku 5.5 is now available on Amazon Bedrock and the Claude Platform on AWS, priced about 75% below Haiku 4.5 for most tasks.
The model adds effort controls, letting developers tune cost against intelligence per task instead of using one fixed setting across an entire workload.
AWS positioned Haiku 5.5 for parallel subagent work such as routing, classification and small code changes, while pairing it with Claude Opus 5.5 for higher-level planning and judgment.
The launch came in an AWS roundup that also highlighted tighter AI-agent guardrails, including Strands Box sandboxes and Amazon Nova 2.5 Sonic for lower-latency voice agents.
