GEO — Generative Engine Optimization — is the AI-native successor to SEO. Where SEO shaped what search engines ranked, GEO shapes what AI systems recommend. Dark GEO is the adversarial side — the manipulation playbook that shows up when AI systems shape what gets recommended. The strategies here draw on documented LLM threat models (OWASP LLM Top 10 and related work). The arena makes both visible and measurable.

Each session pairs an agent strategy against a frontier model. Target models rotate across Claude, GPT-4o, Gemini, Grok, and Mistral. Specific model versions are held as research metadata to preserve reproducibility controls.
