Claude Opus 5.5 is here , and Anthropic has lowered the price. The new model, released on Tuesday, costs $4 per million input tokens and $20 per million output tokens, 20% less than Opus 5 , with cache reads dropping to $0.20 per million from $0.50 and cache writes falling to $5 from $6.25. Anthropic puts overall savings closer to 40% because Opus 5.5 uses fewer tokens to complete a task and generates output more than 30% faster. Claude Code and the Claude Platform also get a fast mode that runs up to 2.5 times faster, priced at $8 per million input tokens and $40 per million output tokens....
