What changed

Claude Haiku 5.5 is available through the Claude Platform, AWS, Google Cloud, and Azure for summaries, compaction, classification, browser use, and coding subagents.

What it means for you

Teams can lower the cost of many short calls, but should test quality, latency, and prompt length on their own workload before migrating.

Anthropic released Claude Haiku 5.5 on October 7. The small Claude model targets high-volume, cost-sensitive work such as summaries, compaction, classification, browser use, and coding subagents; its listed API model ID is claude-haiku-5-5.

For prompts up to 100K tokens, the official price is $0.10 per million input tokens and $0.50 per million output tokens; above that threshold, it is $0.50 and $2.50. It is available on the Claude Platform, AWS, Google Cloud, and Microsoft Azure. Anthropic also cut Claude Sonnet 5.5 cache reads from $0.20 to $0.10 per million tokens.

This is a lower-cost Claude route for many short calls, not a substitute for production evaluation. Compare quality, latency, cache-hit rate, and total cost on real work; keep complex, long-running coding with Claude Sonnet 5.5 or a larger model. See the Anthropic announcement.
