Lower Costs: Input starts at USD 0.10 and output at USD 0.50 per million tokens for prompts up to 100,000 tokens, according to the provided article.
Expanded Capabilities: A context window of up to one million tokens supports processing large documents, codebases, and detailed records.
Smarter Model Selection: Businesses can use Haiku for high-volume tasks and reserve more capable models for complex reasoning.
Anthropic has added Claude Haiku 5.5 to its AI model lineup, with a clear goal: deliver stronger results at a much lower cost. The new model targets tasks such as software development, customer support, data analysis, and computer control. Its low price and large context window make it a useful choice for businesses that need AI to handle many tasks each day.
Claude Haiku 5.5 offers a major price cut compared with earlier models in the Haiku family. Anthropic lists its standard price at USD 0.10 per million input tokens and USD 0.50 per million output tokens for prompts up to 100,000 tokens. Longer prompts have higher rates. This price structure can help businesses reduce costs when AI systems handle large amounts of text or repeat the same tasks many times.
The lower price does not mean the model serves only basic needs. Haiku 5.5 can support text summaries, data extraction, customer queries, code review, and other routine work. Companies can also use it for minor tasks within larger AI systems. A more powerful model can handle complex decisions, while Haiku 5.5 takes care of simpler steps at a lower cost.
Claude Haiku 5.5 supports a context window of up to one million tokens and can produce up to 128,000 tokens in a single response. A context window sets the amount of information a model can process at one time. This large limit can help with long reports, large code files, detailed records, and tasks that require many pieces of information.
The model also supports adaptive thinking, which lets developers adjust the effort level for a task. A simple request may need little reasoning, while a harder task may need more. This control gives developers a way to balance speed, cost, and answer quality. The right setting depends on the task and the level of accuracy that it requires.

Anthropic reports strong gains over Claude Haiku 4.5 in several tests. On the OSWorld 2.1 computer-use benchmark, Haiku 5.5 scored 72.4%, compared with 15.7% for its predecessor. The test checks how well an AI model can work with a computer interface. This result points to a major step forward for tasks that require screen control and action across software tools.
The model also scored 45.9% on Humanity’s Last Exam without tools, compared with 10.2% for Haiku 4.5. With tools, its score rose to 57.4%, while Haiku 4.5 reached 18.7%. On Terminal-Bench 4.0, a test for coding tasks in a command-line environment, Haiku 5.5 scored 39.2%, while Haiku 4.5 scored 0.0%.
These figures come from Anthropic’s own published tests, so they do not prove that the model will deliver the same gains in every real-world task. Still, the results show that Haiku 5.5 offers a much stronger option for several types of AI work.
Anthropic offers different Claude models for different levels of work. Haiku 5.5 targets speed, low cost, and high-volume tasks. Sonnet 5.5 serves as a more capable choice for general coding, knowledge work, and AI agents. Opus 5.5 targets demanding tasks that need deeper reasoning.
The standard rates for prompts up to 100,000 input tokens reflect these differences. Sonnet 5.5 costs USD 2 per million input tokens and USD 10 per million output tokens. Opus 5.5 costs USD 4 per million input tokens and USD 20 per million output tokens. Haiku 5.5 costs far less than both models.
This setup gives businesses more control over AI expenses. A company can assign Haiku 5.5 to classify records or extract details, then use Sonnet or Opus for tasks that need more advanced analysis. Such a system can reduce costs without forcing every task through the same model.
Teams that plan to move from Haiku 4.5 should review a few technical changes. Anthropic notes that the new tokenizer counts the same text as about 30% more tokens. The lower rates may still lead to savings, but actual costs depend on the amount of text and the type of work.
Developers should also review the new default for adaptive thinking, changes to some API parameters, and updates to assistant-message prefill support. Applications must handle refusal responses correctly as well. These checks can help prevent errors after a switch to the newer model.
Why this MattersClaude Haiku 5.5 could prove useful for those businesses looking for effective AI tools at affordable prices. The cost-effectiveness of this system could help firms automate processes, develop useful software, and process massive amounts of information. Thus, the pricing and performance of this algorithm could provide businesses with the opportunity to implement AI in their day-to-day operations.
