Error Budget
In the SRE framework, it refers to the allowed failure margin equal to 100% minus the SLO, determining when to stop releasing new features and shift to fixing reliability. Together with SLIs and SLOs, it forms a closed loop.

An SLI is the actual measured value, an SLO is the internal target the team sets for the measured value, and the error budget is the room for failure allowed by 100% minus the SLO; the three form a closed loop.
For AI systems, attaching the SLO only to availability means model quality degradation will never exhaust the error budget, and thus will never trigger the brake.
SLOs (Service Level Objectives) and error budgets: mature platforms usually set quantitative targets for availability and use them to drive capacity planning and failure drills.
The error budget concept originated from Google SRE practices, quantifying reliability targets as an upper limit on allowable downtime and establishing a quantifiable trade-off framework between stability and release velocity.
