Evidence scope
This page is an index of existing public evidence and provider-documented identities. Inclusion does not imply an OpenGPT endorsement or a universal rank. Anthropic: claude.
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.
