Plain reads on cutting the AI bill

Most AI bills grow for the same few reasons: long agent sessions resend their history on every turn, the strongest model answers easy questions, the same context is paid for again and again, and work that could wait runs at full price.

Some posts are about cost directly. Others cover the groundwork that makes a saving measurable and safe: a key per person and per agent, budgets with hard caps, and what a clean offboarding looks like. Where a post uses an example, it says so. We do not publish customer results we cannot show you.
