Anthropic has released Claude Haiku 5.5, a small AI model priced around 75% less than Haiku 4.5 on average, and is halving cache read prices for Claude Sonnet 5.5.
Anthropic has released Claude Haiku 5.5, which the company describes as the cheapest, fastest, and most capable small model it has ever released. The model is designed for high-volume, cost-sensitive tasks such as summaries, database queries, and classification requests.
On average, Claude Haiku 5.5 costs around 75% less to run than Haiku 4.5. The company states it is priced 90% lower than Haiku 4.5 for requests up to 100,000 tokens and 50% lower for requests over 100,000 tokens.
The price per 1 million tokens for Haiku 5.5 is:
The first price in each pair applies to prompts up to 100,000 tokens; the second applies to prompts over 100,000 tokens.
Alongside the launch, Anthropic is halving the price of Claude Sonnet 5.5’s cache reads. Cache reads now cost $0.10 per million tokens rather than $0.20, which the company says makes Sonnet 5.5 run around 20% cheaper on most agentic work.
Anthropic provided benchmark results comparing Haiku 5.5 with Haiku 4.5, GPT-6 Luna, and Sonnet 5.5:
Claude Haiku 5.5 is available now on all platforms, including Amazon Web Services, Google Cloud, and Microsoft Azure. On the Claude Platform, developers can use claude-haiku-5-5.
Anthropic is also introducing a new monthly API credit for Claude Max, Ultra, and Team subscribers. Max users will get $100 in credits per month, Ultra users will get $200, and Team subscribers will receive up to $500, pooled across their users.
The release gives developers a lower-cost small model option for high-volume tasks, while the Sonnet 5.5 cache read price cut reduces costs for agentic work. The new monthly API credits are intended to support users building agents and applications on the Claude Platform.
