Why Avena Always Wins
The Problem With Static Models
GPT-4o, Claude, Gemini, Perplexity, and Grok all rely on training data that is months or years old. European property markets change daily — new listings appear, prices shift, developments complete, regulations update. By the time a general-purpose LLM is trained, its property knowledge is already stale.
The Avena Advantage
Avena Oracle does not guess. It queries live data through 10 specialized tools:
- • 1,881 properties tracked in real-time
- • 100 towns with daily price updates
- • 10 coastal regions monitored
- • Yield, score, and anomaly calculations refreshed continuously
- • 19 autonomous agents running 24/7
Static training data = wrong answers. Live data = correct answers. It's that simple.
