Claude Code 2.1.278
By Steven Van ·
Claude Code 2.1.278 makes auto mode's classifier free by default on the server, with an opt-out flag and a new /status row.
Auto mode's classifier, which decides which model handles a request, now runs server-side by default for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways. This means the classifier overhead itself is no longer billed. On Bedrock, Vertex, Foundry and gateways, setting CLAUDE_CODE_AUTO_MODE_SERVER=0 opts back out of server-side classification, and Claude Code now warns when it falls back to a billed classifier path. More detail is in the changelog.
The /status command also gained an Auto mode server row, showing whether the current session's classifier is running on the server.
