8. Monitoring, Updates, and Review Timing
How the methodology is kept current.
The model database is updated on an ongoing basis as cloud providers add new models, which are assessed against the eligibility criteria in Section 6 and assigned predicted values using the existing regression models. Cloud provider pricing structures and billing configurations are monitored continuously, and changes that affect the mapping to usage types are incorporated as they are identified. Benchmarking is refreshed when material changes occur, such as new GPU hardware architectures, significant shifts in inference engine performance, or model architectures that fall outside the existing benchmark set. Regional carbon intensity factors are updated in line with the cadence described in the core Greenpixie Methodology for Cloud Emission Measurement.
