Claude Haiku 5.5
Claude Haiku 5.5 is positioned for fast, lower-cost, narrowly scoped work—not as the best choice for every complex agentic task.
Why it matters: Teams can consider Haiku 5.5 where speed and cost matter for repetitive or bounded tasks, while reserving larger models for complex agentic coding. Prompt length matters to the quoted pricing, and the benchmark evidence includes an offline subset.
