Anthropic Cuts Haiku Model Prices by 75%, Launches 1M-Token Context Version

Anthropic released Claude Haiku 5.5 on October 7, 2026, slashing prices by up to 75% compared to its predecessor while expanding the model's context window from 200,000 to 1 million tokens. The fastest and cheapest model in the Claude lineup now costs $0.10 per million input tokens and $0.50 per million output tokens for prompts under 100,000 tokens, with tiered pricing for longer inputs. In the same announcement, Anthropic halved the prompt-cache read cost on Claude Sonnet 5.5 from $0.20 to $0.10 per million tokens, reducing overall agentic-task costs by roughly 20% for applications relying on cached prompts.
