What is changing?
Anthropic released Claude Haiku 5.5, the newest member of its small-model family, on October 7. It is designed for high-volume workloads such as summarization, context compaction, database queries, classification, routing and coding subagents. Haiku 5.5 supports adaptive thinking with an adjustable effort level, a 1-million-token context window and up to 128,000 output tokens.
For prompts up to 100,000 tokens, input costs $0.10 per million tokens and output costs $0.50. Above that threshold, the rates rise to $0.50 and $2.50 respectively. Anthropic says the average cost to run the model is about 75% lower than Haiku 4.5 after accounting for tokenizer and workload differences; this is the provider’s own calculation.
The model is active on the Claude API, Amazon Bedrock, Google Cloud, Microsoft Foundry and Claude Platform on AWS. In the same announcement, Anthropic halved Sonnet 5.5 cache-read pricing to $0.10 per million tokens.
