What is the pricing for Claude Opus 5?

Claude Opus 5 is priced at $5 per million input tokens and $25 per million output tokens, identical to the pricing of its predecessor, Claude Opus 4.8.

A separate Fast mode, offered as a research preview, costs roughly double the standard rate - $10 per million input tokens and $50 per million output tokens - in exchange for output that's about 2.5 times faster.

Because pricing didn't change from Opus 4.8, the practical cost impact of migrating comes less from the sticker price and more from behavioral differences, like thinking now running by default, which can change how many tokens a given request actually consumes.
