Cursor users face unexpected costs due to default fast model in subagents

By PulseAugur Editorial · [1 sources] ·

A Cursor user discovered that the application's subagents, such as Explore, Bash, and Browser, default to using the more expensive "composer-2.5-fast" model, even when the user has explicitly selected the cheaper "composer-2.5-standard" model. This behavior led to unexpectedly high costs for the user, as the "fast" variant is approximately six times more expensive per token. Cursor support confirmed this is expected behavior, stating it's necessary for agent functionality, but the user questions the necessity of the faster, costlier model for background tasks. AI

IMPACT Highlights potential cost-management issues for users of AI-powered tools and the importance of transparent default settings.
