Anthropic Launches Claude Haiku 5.5 With API Prices Starting at $0.10

Anthropic unveiled Claude Haiku 5.5, an affordable AI model priced as low as 10 cents per million input tokens, making it one of the cheapest options for developers. This new version demonstrates significant performance improvements, scoring 72.4% on the OSWorld 2.1 offline subset, a substantial gain from 15.7% in the previous Haiku 4.5.

It also outperformed GPT-6 Luna on several evaluations. With adjustable effort settings, developers can control the model's computing power for each task. Early customer testimonials suggest that Haiku 5.5 can reduce latency and improve inference speed. Anthropic has also cut Sonnet 5.5 cache-read prices by 50%, potentially cutting costs by around 20% for agentic workloads.

Users with Max and Team subscriptions will receive monthly API credits. For developers, Haiku 5.5 can be used for simpler, repetitive tasks, while more powerful models like Sonnet and Opus are better suited for complex assignments.
