# Spend limits What stops spending on ZeroLog, and what does not. Your credit is the hard stop. the line you set ## At the limit, work stops the limit - Your credit - Delegated work, per chat turn nothing runs here - /goal run time, per run *Three limits that are built. At any of them, work **stops**: it does not continue and bill you later. Paid models stop at zero credit. Delegated sub-agents draw from a default cap of CHF 0.50 per chat turn, with at most four delegated calls. A /goal run ends at the time limit of your [plan](https://zerolog.ch/docs/plans).* what is not there ## No default spend cap per run, per chat or per agent No plan sets a spend cap per run by default, and there is no spend limit per chat. A long agent run can use all the credit you have until the run ends or the credit reaches zero. A run only carries a ceiling if one is given when it starts: `/ultracode` accepts a maximum spend, and the run stops when it reaches it. Check your credit and your plan's run time before you start a long run. A monthly budget governor exists, but the operator sets it, not you: see [Budget governor](https://zerolog.ch/docs/governor). choosing a model ## Check the price before you send The picker shows the models available to your account and their current prices. Choose one that fits your budget. If a model is unavailable, follow the message in chat or pick another model from the list. not a spend limit ## Hardware and abuse limits live elsewhere This page is about money. How much CPU, memory and disk a container gets, how many run at once, and how long an agent may run are set by your [plan](https://zerolog.ch/docs/plans). A few actions, such as signing in, are separately rate-limited to slow down automated abuse; if one stops you, wait a moment and try again. How unattended runs behave: [/goal and /ultracode](https://zerolog.ch/unattended-agents). ## What stops spending Mermaid source of the diagram on this page: ```mermaid %% Spend limits: what stops spending.
