Anthropic Claude Code Auto Mode Defaults to Server-Side Classifier, Reduces Billing Overhead
Anthropic has updated the default behavior for Claude API, Enterprise, Bedrock, Vertex, Foundry, and gateway users employing auto mode. This change routes classifier operations to a server-side service, eliminating charges for classifier overhead. Users can opt out of this new default via an environment variable (`CLAUDE_CODE_AUTO_MODE_SERVER=0`) on supported platforms. A new status row in `/status` indicates if the server-side classifier is active for the session.

Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead (CLAUDE_CODE_AUTO_MODE_SERVER=0 opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback.
