# In the News: September 19, 2026


Anthropic released Claude Code 2.1.278 today. Auto mode's safety classifier now
runs on the server and is not billed, on the Anthropic API and on the major
cloud platforms. The exception is a session whose traffic passes through a
company LLM gateway that rewrites it. Those sessions keep paying.

## 1. Claude Code stops billing server-side auto mode checks

**[Claude Code changelog, version 2.1.278](https://code.claude.com/docs/en/changelog)** · Anthropic · September 19, 2026

In auto mode a classifier checks actions such as shell commands and network
requests before they run. Anthropic's documentation says that from 2.1.278
Claude Code asks the server to perform those checks as part of the session's own
model requests, and "doesn't charge for them when the server performs them."
Server-side checks are on by default on the Anthropic API, Claude Platform on
AWS, Amazon Bedrock, Google Cloud's Agent Platform and Microsoft Foundry. Pro,
Max and Team plans never see the dialog. When the server's checks stop reaching
a session, Claude Code falls back to its own classifier requests, billed as
before, and holds the next checked action behind a message reading "Auto mode is
now free. This session isn't set up for that yet." A new `Auto mode server` row
in `/status` reports which side of that line the current session is on.

The documented cause is an LLM gateway or proxy that strips or rewrites request
headers, drops request fields it does not recognise, or edits responses by
rewriting IDs or dropping keys from streaming events. Outside Amazon Bedrock
sessions running a model older than Claude Opus 4.8, Anthropic says the dialog
should appear only in that case. A team that already knows its gateway cannot
carry the checks can set `CLAUDE_CODE_AUTO_MODE_SERVER=0` to suppress the dialog
and keep the billed behaviour. The documentation calls that variable "a
temporary measure that exists to avoid disrupting existing workflows" and says
Anthropic intends to deprecate and then remove it.

**Why it matters:** A gateway that rewrites requests or responses can now add
classifier charges to every auto mode session. The gateway operator must
preserve the server-side checks for users to receive the billing change. Teams
can check the new `/status` row before assuming their fleet is using the free
server-side classifier.
