Anthropic released Claude Haiku 5.5 on October 7, 2026, pricing it at 0.10 U.S. dollars per million input tokens and 0.50 dollars per million output tokens below 100,000 tokens of context, with rates rising to 0.50 and 2.50 above that threshold. The company estimated realistic workloads see about 75% savings versus earlier tiers, even as headlines cited up to 90%. Sonnet 5.5 cache reads were also quietly halved to 0.10 dollars. The launch landed on the same day OpenAI set GPT-6 Luna at identical 0.10/0.50 dollar pricing, a convergence analysts read as a clear price floor rather than coincidence. Haiku 5.5 is positioned as Anthropic's fastest, lowest-cost model for high-volume, latency-sensitive tasks. The pricing pressure comes as several labs race to make persistent AI workers economically practical to run at scale.
