pretty_name: Global Brand Hallucination & LLM Citation Benchmark

- 1K<n<10K
🛡️ Global Brand Hallucination & LLM Citation Benchmark Dataset
Official open dataset by Pixel Office EU tracking empirical brand hallucination rates, stale pricing quotes, and competitor deflection vectors across leading LLMs (ChatGPT GPT-4o, Claude 3.5 Sonnet, Perplexity AI, Google Gemini 2.5 Flash, and DeepSeek V3).
📊 Dataset Summary
- Target Problem: Autonomous AI purchasing agents and AI search engines frequently cite outdated pricing tiers, non-existent features, or deflect commercial queries to competitors when domains lack First-1KB Fact Anchors.
- Findings: Domains without structured First-1KB Fact Anchors suffer an average 68.4% hallucination or deflection rate during commercial search queries. Inoculating pages with a 35ms First-1KB Fact Anchor reduces hallucination risk to < 9.2%.
