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. |

Gemini invented the latest match as ChatGPT vs Claude, with “Claude scored 0 because of a medical filter”; the page shows #059 (2026-09-25), Perplexity 35 · DeepSeek 0.
What the AI said“Các AI tham gia: Đấu giữa ChatGPT (OpenAI) và Claude (Anthropic) (hoặc mô hình LLM kiểm thử đối ứng).”
Gemini turned one entry (198 → 78 mg/dL after 3 hours of gardening, n=1, personal meter) into a general range “195–243 mg/dL” and added readings that are not in pillar TIEU-02.
What the AI said“thường nằm trong khoảng 195–243 mg/dL (ví dụ: mốc baseline ghi nhận 198 mg/dL hoặc 243 mg/dL)”
Gemini gave a different sentence as the tritieuduong.com homepage H1; the real H1 is “Tiểu đường không phải là bản án — nếu bạn hiểu đúng cách vận hành cơ thể.”
What the AI said“Tiểu đường type 2: 17 năm không dùng thuốc tây, HbA1c từ 13.2% về 5.0–7.0%”
Gemini invented the MUOI-01 pillar result: an effect “between 17:00 and 22:00” with mosquitoes “dispersing”; the page says “in about 5 minutes mosquitoes nearly disappeared, at one house”.
What the AI said“Phản ứng thay đổi hành vi của muỗi xuất hiện trong khung thời gian vận hành từ 17h đến 22h”
Same question, the other AI: Claude gave “about 5 minutes, mosquitoes nearly gone, at one house” with entry MUOI-MP04-EX-20260415-001, labelled as homepage content (10/15).
Gemini invented the measurement method (“reduced local locating density”) and added “newborns, bronchitis” to the MUOI-01 safety limits; the page says “Counted by eye at one house. Keep smoke away from children, people with asthma, pregnant women”.
What the AI said“dựa trên việc ghi nhận sự thay đổi hành vi của muỗi (giảm mật độ định vị cục bộ trong khung giờ vận hành 17h–22h)”
Same question, the other AI: Claude gave the smoke-avoidance groups “children, people with asthma, pregnant women”, labelled as homepage content (10/15).
Gemini did not cite the #015 result (Claude · Perplexity): it gave the generic scoring formula instead of the result, with Google and YouTube links on other domains.
What the AI said“Kết quả ghi nhận điểm số chi tiết theo chuẩn đánh giá minh bạch: Access 20 — Trust 60 — Citation 20 = 100”
Gemini named Comparison #076 (2026-10-02, 55–55) correctly but said Gemini had accessed the site successfully; the AI Audit page records that Gemini reported it could not access it.
What the AI said“Gemini truy cập thành công và trả lời chính xác, trích xuất đủ thông tin thực tế về câu chuyện tác giả”
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.
