Leaderboard changes & version history
See what moved, what first appeared, and how exact model versions differ—without mixing sources or inventing missing data.Change data is source-specific
Rank movement is calculated only between comparable LMArena Text Style Control overall snapshots. LiveBench remains current-only until OpenGPT has verified comparable historical snapshots; paused sources stay historical and are not used as current evidence.

Rank movement
Exact publisher record IDs are compared. New entries are not treated as rising from zero and can push existing records down, so a lower rank does not prove lower model quality.409

Why only one ranking has movement data
The frozen June and July LMArena snapshots use the same documented method epoch. The rolling current snapshot is shown separately above; earlier archive periods are labeled separately. OpenGPT has not frozen a comparable prior edition for the other ranking sources, so no movement is shown for them.
Version differencesCompare two catalog model IDs from one model family. Provider IDs, sources and published ranking signals are shown; OpenGPT catalog classification is labeled separately.

No verified feature-difference data is available. OpenGPT does not infer speed, price, context length, or quality.
Historical snapshotsOne frozen source snapshot is preserved for each calendar month. The manifest publishes a SHA-256 file check, and the generator refuses silent replacement.

Earlier records were imported later from LMArena’s official full-history dataset. They are source snapshots, not OpenGPT editions claimed to have been published at those earlier dates.
