AI models' response capability more critical than generation in simulated buyer tests

By PulseAugur Editorial · [1 sources] ·

A developer built an open-source tool called MarketMirror to simulate buyer responses to marketing campaigns using AI models. The tool tested three different LLMs—Claude Sonnet, Codex, and Gemini 3.8 Flash—by creating 2,999 simulated buyers across various demographics and locations. The results indicated that the AI model responsible for interviewing and responding to the simulated buyers was more critical to the campaign's success than the model that generated the initial buyer personas.
