Claude Code's new Concise output style will not cut your token bill.

Anthropic added it in 2.1.237 on August 20, selectable under Output style in /config or settings.json. The r/ClaudeAI thread asking whether it reduces consumption drew 219 upvotes and a clear consensus of no: cost sits in input context, file reads, and reasoning traces, not user-facing output. One user posted the system prompt showing it technically adds tokens per request, and the new styles are injected as a system-reminder every turn, unlike the older Explanatory and Learning styles. r/ClaudeAI Use it because agent chatter is noise in an unattended run, not because it saves money.
