How OpenGPT handles this evidence

Official identities come from provider documentation. Public ranking signals are attached only where the source label and exact catalog version have a reviewed mapping.

Comparison boundaries

Models in one provider or family are not interchangeable; mode, version, lifecycle, tools, and service tier may change results.
Absence from a public ranking means no comparable published signal was mapped, not a score of zero.
Provider documentation establishes identity, not independent quality or suitability.
