Ranking basis
Full published ranking and official model IDs
The main ranking preserves every publisher record and shows its source model ID or source name. Every row can be compared: exact, configuration-safe mappings use official versions; all other rows stay within one source ranking. Missing data never becomes a zero score.- 91 official model IDs

How to read this research edition
Scores stay on their original publisher scales. They are not combined into a composite score.
Missing data does not mean zero. It means the publisher did not report that metric for this snapshot.
When a source reports model settings, the position applies to that exact setup and source release—not every task, region, or deployment.
No provider can pay for placement. OpenGPT links directly to the evidence used.
