Anthropic reversed a planned billing change to its Claude Agent SDK on the very day it was set to take effect. The change would have moved Agent SDK usage — used by third-party tools like Zed and Conductor — from a shared monthly subscription pool to a separate, capped credit billed at full API rates. Anthropic emailed subscribers saying the change is paused and updated its support docs accordingly. The reversal comes amid a turbulent period for Anthropic, including a US government export control order forcing it to pull two newly released models, a proposed class action lawsuit over advertised usage limits, and competitive pressure from OpenAI. The company says it is working on a revised billing approach but has not given a timeline.
