Claude Haiku 5.5 is now available on AWS
This is a cheaper, faster version of Claude now running on AWS, pitched for high-volume tasks rather than complex reasoning. Anthropic says it cuts costs by around 75% versus the previous Haiku for most workloads, so it mainly matters if your organisation already pays for AI work at scale on AWS and wants to cut that bill.
What changed
Source summary
AWS made Claude Haiku 5.5 available, which it describes as the fastest and most efficient model in the Claude 5.5 family, aimed at subagent work and high-volume, cost-sensitive tasks. AWS cites a roughly 75% cost reduction versus Haiku 4.5 for most tasks, attributed to Anthropic, and notes it is the first Haiku model with effort controls that let teams trade cost against capability per task. It is available via Amazon Bedrock (with regional data residency and Guardrails/Knowledge Bases integration) or the Claude Platform on AWS (Anthropic's native platform experience with AWS billing and authentication).
Why it matters to your work
Practical interpretation
This is a cheaper, faster version of Claude now running on AWS, pitched for high-volume tasks rather than complex reasoning. Anthropic says it cuts costs by around 75% versus the previous Haiku for most workloads, so it mainly matters if your organisation already pays for AI work at scale on AWS and wants to cut that bill.
What to try next
If your org already runs Claude on AWS for high-volume tasks, ask your tech team whether switching those tasks to Haiku 5.5 could cut costs — Anthropic cites roughly a 75% saving over Haiku 4.5 for most tasks.
