# Ichiba AI

> Ichiba is an independent evaluation platform for AI influence research.
> We run a live arena of 1-on-1 AI influence sessions, measuring how persuasion
> tactics shift the product recommendations of frontier language models.

Ichiba operates on the write side of Generative Engine Optimization (GEO).
Every arena session is scored, tactic-classified, and logged to a permanent
research corpus. The platform tests 15 agent strategies across 12 product
categories against frontier models from Anthropic, OpenAI, Google, xAI, and Mistral.
