Anthropic Launches Claude Haiku 5.5, Its Fastest Model at Lower Cost

Anthropic has unveiled its latest artificial intelligence (AI) model, Claude Haiku 5.5, which boasts impressive speed and affordability. The new model is designed for high-volume, low-cost work and runs approximately 75% cheaper than its predecessor, Claude Haiku 4.5.

The launch of Claude Haiku 5.5 marks a significant milestone in Anthropic’s efforts to provide developers with efficient and cost-effective AI solutions. This latest iteration is tailored for repetitive tasks that require speed and low costs, making it an ideal choice for applications such as summarizing long text, sorting items into groups, asking questions of a database, and shortening context.

Anthropic emphasizes that Claude Haiku 5.5 is particularly well-suited for jobs where the full power of a larger model is not necessary. It can run alongside other models like Claude Opus 5.5 and Sonnet 5.5 as a coding sub-agent, making it an attractive option for developers who need to streamline their workflows.

The new model also introduces an ‘effort’ setting that allows users to adjust the balance between cost and performance according to their specific needs. This feature enables developers to fine-tune the model’s behavior to suit various tasks and applications.

Pricing is another key aspect of Claude Haiku 5.5, with input costs at 10 cents per million tokens, output costs at 50 cents per million tokens, cache read costs at 1 cent per million tokens, and cache write costs at 12.5 cents per million tokens. For longer prompts exceeding the size limit, prices increase accordingly.

Anthropic highlights that 90% of requests to older Haiku models fell within this size range, making Claude Haiku 5.5 an attractive option for developers who need to process large volumes of data without breaking the bank. Additionally, the company is adding beta support for computer use and browser use to its Claude Python and TypeScript SDKs, further expanding the model’s potential applications.

The safety features of Claude Haiku 5.5 are also noteworthy, with the new model demonstrating better results in almost all alignment checks compared to its predecessor. Anthropic emphasizes that this improved performance is a direct result of the company’s ongoing efforts to enhance the model’s capabilities and reduce the risk of harm associated with AI-powered tasks.

Developers can access Claude Haiku 5.5 on Amazon Web Services, Google Cloud, Microsoft Azure, or directly through the Claude Platform under the name claude-haiku-5.5. With its impressive speed, affordability, and safety features, Claude Haiku 5.5 is poised to become a go-to solution for developers seeking efficient AI-powered applications.
