What was announced?
In AWS What's New, AWS announced that Claude Haiku 5.5 is available on AWS. It is the fastest and most efficient model in the Claude 5.5 family, built for subagents and high-volume, cost-sensitive work.
Why it matters
According to Anthropic, it costs around 75% less than Claude Haiku 4.5 for most tasks. It is also a significant step up from Haiku 4.5 across coding, tool use, computer use, and agents.
What changes
Haiku 5.5 fits work where speed and cost matter most.
- Real-time experiences like voice agents, live support, and in-app assistants
- High-volume tasks like classification, summarization, and pulling key fields from documents
- Fast, cost-efficient subagents
For example, a more capable model like Claude Opus 5.5 can plan the work and hand off well-defined coding, tool use, and browser automation tasks to Haiku, which makes running many agents in parallel practical.
Dive Deep
Haiku 5.5 is the first Haiku with effort controls, so you can tune cost against intelligence for each task.
There are two ways to access it.
- Amazon Bedrock: keeps your data within AWS infrastructure with regional data residency, and gives you AWS-managed features such as Guardrails and Knowledge Bases through a unified service
- Claude Platform on AWS: direct access to Anthropic's native platform experience and capabilities through the AWS Console
Check the Amazon Bedrock documentation for regional availability.
Wrap-up
- Claude Haiku 5.5 is available on AWS
- Around 75% lower cost than Haiku 4.5 (according to Anthropic)
- First Haiku with effort controls for balancing cost and intelligence
- Available through Amazon Bedrock and Claude Platform on AWS
This is great if you want to cut the cost of real-time responses, high-volume jobs, or multi-agent setups!
