To add some clarity: you don't pay extra. It's the same subscription, same price per month. What's new our sub now covers two separate pools: · Interactive → sub limits, unchanged · Programmatic → new $20–$200 included(!!) credit, metered at API rates Community note: This is missing key context: programmatic use no longer draws from subscription limits. It uses a separate $20-$200 monthly Agent SDK credit, then extra usage is billed at standard API rates, so heavy sub users may get far less usage than before. support.claude.com/en/articles/15… platform.claude.com/docs/en/about-… support.claude.com/en/articles/12…
