Anthropic launches Claude Opus 4.5 with API pricing of 5/25 USD per million tokens
Claude Opus 4.5 cuts API pricing to 5 USD per million input tokens and 25 USD per million output tokens, with better agentic and coding performance.
Anthropic has announced Claude Opus 4.5. The new model cuts API pricing to 5 USD per million input tokens and 25 USD per million output tokens. According to the company, Opus 4.5 is also improved in agentic capability and coding performance.
A token is the unit that measures how much text a model processes; API cost is usually charged separately for tokens sent in and tokens generated. Splitting the two prices reflects the fact that most of the cost sits on the output side. With the new pricing, cost planning becomes easier for businesses deploying at scale.
For businesses, price is often the factor that decides which model is used for which task. A lower price for a top-tier model opens the possibility of using it for more work, instead of reserving it for important cases only.
What to keep in mind is that list pricing per token is not the whole operating cost. The actual number of tokens depends on request length, the context sent along and the number of steps in an agentic workflow, so cost can rise quickly without controls.
