Haiku 5.5 lowers token prices for narrowly scoped agent tasks.
Summary
Released October 7 with adjustable effort. On Claude Platform, input/output cost US$0.10/0.50 per million tokens for prompts up to 100,000 tokens; above that, US$0.50/2.50. Sonnet 5.5 cache reads fall to US$0.10. Reported performance is Anthropic’s; tokenizer changes mean token prices alone do not establish task savings.
