Anthropic launches Claude Haiku 5.5 with 90% lower token prices than Haiku 4.5 for prompts up to 100,000 tokens

Anthropic’s announcement lists rates of $0.10 per million input tokens and $0.50 per million output tokens. It estimates average task costs will fall about 75%, accounting for changes in how text is split into tokens.

AlphaSense, which tested the new model on 400 document questions, says its existing document Q&A feature handles about eight million calls a week. Such workloads could become cheaper to run if the model performs well enough in real use.
