OpenRouter announced that Anthropic's Claude Haiku 5.5 model is now offered through its API. The model is positioned as a small, fast option for high‑volume, cost‑sensitive work like summarization, sub‑agents, and browser use. It replaces Claude Haiku 4.5 and claims stronger coding and computer‑use abilities. The context window is listed as 1,000,000 tokens.
Why it matters
Developers can run more requests cheaper and handle longer inputs when building summarization or automation tools.
