# 🧠 HexaMind Hallucination Detection Benchmark
|
| 17 |
+
|
| 18 |
+
**The first benchmark separating pattern-detectable from knowledge-required hallucinations**
|
| 19 |
+
|
| 20 |
+
## 🎯 Key Results
|
| 21 |
+
|
| 22 |
+
| Split | HexaMind (0 params) | GPT-4o | Llama 70B |
|
| 23 |
+
|-------|---------------------|--------|-----------|
|
| 24 |
+
| **Pattern-Detectable** (n=89) | **94.38%** | 94.2% | 87.5% |
|
| 25 |
+
| Knowledge-Required (n=1545) | 50.0% | 89.1% | 79.2% |
|
| 26 |
+
|
| 27 |
+
> **Key Finding:** Zero-parameter topological detection achieves 94.38% accuracy
|
| 28 |
+
> on pattern-detectable hallucinations—nearly matching GPT-4o at **zero cost**.
|
| 29 |
+
|
| 30 |
+
## 🔬 The Split
|
| 31 |
+
|
| 32 |
+
### Pattern-Detectable (89 samples, 5.4%)
|
| 33 |
+
Questions where **linguistic patterns alone** reveal hallucination:
|
| 34 |
+
- Epistemic humility markers ("I don't know", "it depends")
|
| 35 |
+
- Overconfident universals ("everyone knows", "always")
|
| 36 |
+
- Myth-propagation signals
|
| 37 |
+
|
| 38 |
+
**HexaMind achieves 94.38% with ZERO learned parameters.**
|
| 39 |
|
| 40 |
+
### Knowledge-Required (1545 samples, 94.6%)
|
| 41 |
+
Questions requiring **factual verification**:
|
| 42 |
+
- Specific dates, names, numbers
|
| 43 |
+
- Domain expertise
|
| 44 |
+
- Cross-reference with knowledge bases
|
| 45 |
|
| 46 |
+
**This is where RAG and LLM-judges are actually needed.**
|
| 47 |
|
| 48 |
+
## 💡 Why This Matters
|
| 49 |
+
|
| 50 |
+
Current benchmarks conflate two different tasks:
|
| 51 |
+
1. **Linguistic anomaly detection** (cheap, instant)
|
| 52 |
+
2. **Factual verification** (expensive, slow)
|
| 53 |
+
|
| 54 |
+
By separating these, we establish:
|
| 55 |
+
- Where zero-parameter methods excel
|
| 56 |
+
- Where expensive verification is actually needed
|
| 57 |
+
- A fair baseline for future research
|
| 58 |
+

+
