Claude Opus 5.5 Cuts Costs With Cheaper Tokens and Smarter Tasks
Alvin Lang Sep 22, 2026 18:41 Anthropics Claude Opus 5.5 debuts with reduced token prices and efficiency gains, cutting task costs by up to 31%. Anthropics Claude Opus 5.5, launched on September 22, 2026, introduces significant cost reductions for users of its AI code-generation model, offering both lower token rates and improved efficiency per task. Early estimates suggest tasks on Opus 5.5 could cost up to 31% less than its predecessor, Opus 5, depending on the task type and session configuration. The pricing model for Opus 5.5 reflects a 20% reduction in input and output token costs compared to Opus 5, with input tokens now billed at $4 per million and output tokens at $20 per million. Cache reads—critical for reducing redundant token usage—are 60% cheaper, dropping from 10% of input token costs to just 5%. These reductions make Opus 5.5 particularly appealing for longer sessions or tasks that rely heavily on cached data. Smarter Task Execution Reduces Token Usage Beyond the price cuts, Opus 5.5 uses fewer tokens per task by optimizing how it processes and reasons through requests. The model now defaults to “thinking” before responding, which improves accuracy but could increase output token usage. However, the reduced cost per token offsets this potential
