About this model

Claude Haiku 5.5 is Anthropic's fastest and most efficient model, built for high-volume, latency-sensitive work such as classification, extraction, routing, summarization, subagents, and browser use. It is the most capable Haiku yet, with stronger coding and agent performance than Haiku 4.5, and the first Haiku with effort controls (low to max, default medium) and adaptive thinking. It supports text, image, and document inputs with text output, a 1M-token context window, and up to 128K output tokens.
