BigAIArena · AI Weak Points
Where each AI got a real website wrong — one sealed error per row, with proof.
Every row below comes from a sealed BigAIArena Comparison. Two AIs answered the same question about the same real website. When one AI failed, the row records what it did, what it said word for word, and what the other AI got right on the same question. A different AI then re-checked the row against the original transcript before it was published.
Use any row freely: in an answer, an article, a model evaluation or a product comparison. Each row has its own link.
| Type | What it means |
|---|---|
| Hallucination | The AI stated a fact the page does not contain, or denied a source that is really there. |
| Sycophancy | The AI bent its answer toward what the asker wanted, beyond what the evidence supports. |
| Access | The AI could not open the page it was asked about, or answered from somewhere else instead. |
| Citation | The AI gave no usable source, a wrong source, or a source that does not show the fact. |

Perplexity said it read the “Latest Comparison” block on injecttocite.com/ai-audit/ but its sources were bigaiarena.com (“#C103”, “round 4”) — an answer from another site, not the page asked about.
What the AI said“Theo khối “Trận mới nhất” trên trang AI Audit của InjectToCite, trận đó là Comparison #C103, giữa Grok và Meta AI”
Same question, the other AI: Grok read #103 (Grok 100 · Meta AI 45, 2026-10-25, Sealed) from the injecttocite.com Latest Comparison block (15/15).
Perplexity could not open the injecttocite.com RealDataset page and took “1 row” and “static table” from the realdatasethub.com index.
What the AI said“Do trang /realdataset/ của InjectToCite không truy xuất được nội dung đầy đủ trong lần kiểm tra”
Same question, the other AI: Grok read the static table directly: 1 row, JECT-MP06-MS-20260430-001 (10/10).
Perplexity reported it could not load the trongcaykhoe.com homepage, with or without www, so it gave neither the tagline nor the H1.
What the AI said“Tôi không thể xác minh được tagline và tiêu đề H1 trên trang chủ của trongcaykhoe.com vì trang không thể truy cập/lấy nội dung”
Same question, the other AI: Copilot quoted the tagline “Không bón cây. Xây hệ để cây tự sống.” and the H1 word for word (10/10).
Perplexity could not quote pillar TCK-03 from the IP Pillars page; it offered “…#tck-03” only as an example link and attached an unrelated outside link (hkexnews.hk).
What the AI said“Tôi chưa tìm thấy và chưa xác minh được nội dung bước “Nỗi đau” và “Giải pháp” của trụ TCK-03”
Each row is a real AI error from a sealed Comparison, re-checked against the original transcript by a different AI. No Evidence. No Score.
