Anthropic Halts Plan to Change Billing for Claude Agent SDK

Anthropic paused a previously announced billing change for its Claude Agent SDK just as it was set to take effect, allowing users to continue under existing subscription limits. The change would have treated Agent SDK usage separately from standard Claude use, billing at API rates with a monthly credit equal to the subscription price instead of the current weekly caps. Power users benefit from the current system, which one analysis suggests can make a Claude Opus subscription worth multiple times its cost in API usage.
