Mini Case Study #1: Toyota — Applying PSOS™ Under the AIVO Standard v3.0

Abstract:
This article is the first in a series of mini case studies demonstrating the AIVO Standard’s Prompt-Space Occupancy Score (PSOS™). Each study applies PSOS to a single brand as a preview of the forthcoming AIVO 100™ Global Index.
Case Study: Toyota
Prompts: reliability, hybrid SUV <$50k, safety, EV leadership, family car value.
Models: ChatGPT, Gemini, Claude, Perplexity.

Results:
- Frequency: 80%
- Persistence: 90%
- Decay Adj.: 0.85
- Consistency: 100%
- PSOS = 86.5/100
Interpretation: Strong visibility in reliability and hybrid prompts, weaker in EV-related queries, particularly in Perplexity.
Conclusion:
PSOS provides a transparent, replicable, governance-ready KPI for AI visibility. The AIVO 100 will apply this methodology at scale across 100 brands and 8 industries, launching September 9.
