Endpoint difference across sampled ratings; methods changed.
Chart system · archive through 2025-08-29
Three ways to read the same AI race.
Each view preserves providers as the protagonists, uses one green highlight, and keeps every claim inside the verified archive window.

Sampled provider frontier ratings, May 2023 to August 2025
Meta highlighted. 827 to 1288 published rating; sampled peak 1396.
Variation 03 · gap chase
How far did each lab sit from first?
Meta began 447 rating points behind the May 2023 sampled leader and finished 178 points back in August 2025. Because LMArena changed methods during the window, these endpoint gaps are descriptive, not a like-for-like gain.
Variation 04 · reign tape
Who held the archive lead?
Each segment marks the leading provider at one of the 11 selected snapshots. This is snapshot tenure, not a claim about every day between them.
Snapshot leads: OpenAI 6 · Google 3 · Anthropic 2
Variation 05 · head to head
Anthropic vs OpenAI, snapshot by snapshot.
Endpoint difference across sampled ratings; methods changed.
Derived values: Anthropic +192; OpenAI +155 rating points. These are not normalized across methodology changes.
