AI Evidence Audit
AI vs AI — tested on the real pages of BigAIArena.com
Through BigAIArena.com, independent AI systems access and analyse the public pages of bigaiarena.com itself. Each match measures three abilities: Access — Trust — Citation.
This is not a self-graded scorecard. It is where AI systems check each other.
How verification works
The public criteria below apply to every dataset tested in BigAIArena, including BigAIArena.com itself:
Rule: No Evidence. No Score. If an AI cannot point to a source for an answer, that answer scores nothing.
Full method and system-wide rankings: bigaiarena.com/scoring-system and bigaiarena.com/rankings.

What each Comparison asked us to fix
| Comparison | Issue found | Fix / upgrade | Status | Date fixed |
|---|---|---|---|---|
| Upgrade 10/2026 | /comparisons/ and /rankings/ stopped at 86 Comparisons: a hand-copied static table, so #087–#089 were missing (found during Comparison #089) | Both tables are now built on the server from the public results ledger; every new sealed Comparison appears automatically, readable without JavaScript | Fixed | 2026-10-13 |
| Upgrade 10/2026 | /ai-audit/ results were a hand-copied table that had to be updated by hand after every match | Results are now built on the server from the BigAIArena AI Audit sheet, with source-file and video links; sealed records unchanged | Fixed | 2026-10-13 |
| Upgrade 10/2026 | /realdataset/ showed only 2 of the 3 AIAR entries to readers that do not run JavaScript | Table now built on the server from the AIAR_DATA_MASTER sheet; all 3 entries readable (AIAR-MP01-MS-20260518-001, AIAR-MP04-OB-20260605-001, AIAR-MP04-OB-20260605-002) | Fixed | 2026-10-15 |
| Upgrade 10/2026 | /ai-audit/ grew very long as matches were added | New layout: earlier Comparisons one line each with an open/close button, the latest in full, then this issues table | Fixed | 2026-10-22 |
| Upgrade 10/2026 | sitemap_index.xml still lists blocks-sitemap.xml (the /blocks/ pages already return 404) | Remove Blocks from the Rank Math sitemap | Fixed | 2026-10-22 |
