Lower token costs, not a new plan price
Cursor says changes to its agent harness reduced token costs for users by 7% without reducing agent quality. The changes address how requests are assembled, context is reused and work is divided across agents.
The announcement describes efficiency improvements rather than a subscription price cut. It does not announce new plan prices or usage allowances.

Less repeated context
Cursor says it trimmed roughly 66% of its system prompt. Loading more built-in tools only when needed also cut static-context tool-description tokens by 60%.
Changes to cache reuse reduced the rate of cold cache misses by 20%. These are separate measures of the underlying improvements, not additional percentage reductions in users' bills.
