The point: datasette-llm-limits allows administrators to define daily spending limits for LLM API calls in Datasette to control costs.
A new plugin for Datasette makes it possible to set spending limits for LLM usage — either per user or globally. Configuration is done via the Datasette plugin system.
The datasette-llm-limits plugin integrates with the existing extensions datasette-llm and datasette-llm-accountant. It enables the setting of spending limits for Large Language Models usage within a Datasette instance.
The limits can be configured granularly: either per user (based on the Actor object) or globally for the entire instance. The current example configuration shows a daily limit of $1.00 per user in a rolling 24-hour window. This is defined via the Datasette configuration file, for example under the key limits with sub-parameters scope, window and amount_usd.
For practitioners, this control function is relevant to prevent uncontrolled API costs. Particularly in multi-tenant setups or shared Datasette instances, such a limit protects against surprises in billing. The integration with datasette-llm-accountant suggests that usage is already being measured and can now also be limited.
