Simon Willison calls for hard usage caps by default on metered services
What happened
On October 4, Simon Willison argued that usage-billed services and APIs should ship with a hard budget cap by default: hitting the cap stops service, and only the user can lift it. He points out that coding agents and personal agents lower the barrier to running paid services, and that warning emails alone may not stop costs from piling up. Users can rack up charges while asleep, even waking to surprise bills above $10,000. The core proposal is a default hard budget limit that shuts service off.

Simon Willison 主张按用量计费的服务和 API 默认设置硬预算上限，超额即停止服务，仅在用户主动选择后解除限制。编码智能体和个人智能体降低了运行付费服务的门槛，仅发送警告邮件可能让用户在睡眠期间继续累积费用，甚至收到 $10,000+ 的意外账单。
