- Anthropic introduced Claude Haiku 5.5 and said it was aimed at high-volume, cost-sensitive work such as summaries, database queries and classification.
- The company said Haiku 5.5 was its first Haiku-class model with an adjustable effort setting.
- Anthropic said Haiku 5.5 cost about 75% less than Haiku 4.5 on average and was available on Amazon Web Services, Google Cloud, Microsoft Azure and the Claude Platform.
- It said Claude Sonnet 5.5 cache reads were cut by half to $0.10 per million tokens, lowering most agentic tasks by around 20%.
- Anthropic said Max 5x users would get $100 a month in credits, Max 20x users $200, and Team subscribers up to $500 pooled across users.
Anthropic introduced Claude Haiku 5.5 as a model for high-volume, cost-sensitive work, including summaries, compaction, database queries and classification. It also said the model suited coding subagent work and live customer support because of its speed.
The company said Haiku 5.5 was its first Haiku-class model with an adjustable effort setting. It said average running costs were about 75% lower than for Haiku 4.5, with different pricing depending on token counts.
Anthropic said the model scored better on its alignment evaluations than Haiku 4.5 and showed fewer cases of misaligned behaviour. It said the cybersecurity safeguards were stricter than Haiku 4.5’s, but still allowed more defensive work than some newer models while blocking penetration testing and related attack techniques.
Haiku 5.5 was available on Amazon Web Services, Google Cloud, Microsoft Azure and the Claude Platform. Anthropic also said it had halved cache-read prices for Claude Sonnet 5.5 and would give monthly API credits to Max and Team subscribers.
