## Share Of Model — the new brand-performance metric
In the age of AI-driven content, understanding how your brand is perceived by LLMs is essential. Models like GPT-4o now shape brand visibility by influencing how often and in what context brands are mentioned.
Share Of Model gives marketing teams a way to track, understand and optimise their brand's presence and performance on leading AI-powered search platforms — ChatGPT, Gemini, LLaMA, and others.
