Anthropic、Claude Agent SDK のトークン課金見直しを一時停止

“If you are a developer using Claude as your primary coding assistant with Opus, you will blow past breakeven in the first week,” developer Matthew Diakonov writes in that analysis.

“For anyone using agents heavily, this is a major cost increase,” the developers behind code editor Zed warned its users after Anthropic announced the Agent SDK price change plans.

On Monday, though, Anthropic gave these power users a pricing reprieve, updating its billing support page to say that it was “pausing the changes to Claude Agent SDK usage described below.” The company says that “for now, nothing has changed” and that it is “working to update the plan to better support how users build with Claude subscriptions.” Some users report receiving similar notices viaemailfrom Anthropic.

The sudden pullback on forcing API pricing comes just weeks after GitHub Copilot rolled out its own token-based billing changes, leading to sticker shock for many users who found themselves blowing past the new limits on their subscriptions. It also comes as Anthropic prepares for a possible initial public stock offering by filing confidential papers with the Securities and Exchange Commission.

While the temporary reprieve is welcome news for Claude Agent SDK users, they should probably expect to bear the full costs of their extensive use before long. In April, Anthropic Head of Claude Code Boris Cherny said “our subscriptions weren’t built for the usage patterns of these third-party tools,” referring to automated agent harnesses like OpenClaw that were no longer covered under standard subscription plans. “Capacity is a resource we manage thoughtfully and we are prioritizing our customers using our products and API. … We want to be intentional in managing our growth to continue to serve our customers sustainably long-term.”
