Simon Willison advocates setting hard budget caps by default for AI usage
Start here
Researcher Simon Willison published an article arguing that in the future, hard budget caps should be set by default for almost all AI use cases. He further proposes that usage-based paid services and APIs should have hard budget caps by default, that is, after reaching $X per month, they should be cut off directly and return an error, rather than just sending a warning email; he believes that coding agents and AI agents will lower the barrier to creating paid services, and users may wake up to find that an out-of-control service has already consumed hundreds or even thousands of extra dollars, so the hard cap should be the default and opting out should require an active choice. He mentions that AWS launched a monthly spending cap feature on September 16, pausing projects for the month once the limit is reached, but this new experience is currently only available to a limited set of customers.
