# Claude Code v2.1.278：API和企业用户默认启用服务端分类器

Claude Code发布v2.1.278版本。本次更新将Claude API和企业用户、以及Bedrock、Vertex、Foundry和网关上的自动模式默认切换为服务端分类器，该分类器不收取分类器开销费用。用户可通过设置CLAUDE_CODE_AUTO_MODE_SERVER=0在Bedrock、Vertex、Foundry和网关上选择退出。此变更降低了企业用户的自动模式使用成本。

## English Version

**Claude Code v2.1.278 Defaults to Server-Side Classifier for API Users**

Claude Code released v2.1.278. The update changes auto mode for Claude API and Enterprise users, as well as on Bedrock, Vertex, Foundry, and gateways, to default to the server-side classifier, which does not charge for classifier overhead. Users can opt out on Bedrock, Vertex, Foundry, and gateways by setting CLAUDE_CODE_AUTO_MODE_SERVER=0. This change reduces auto mode costs for enterprise users.
