Zero-Shot Brand Recall
Testing whether a model names your brand, with accurate attributes, from its own parameters, with retrieval switched off and no brand clue in the prompt.
Analogy Mental model
A closed-book recall test. Ask a class to name three Swiss watchmakers and the answers arrive without anyone consulting anything, because those names are simply known.
In practice What you actually do
Run a quarterly comparison: twenty category questions against the base model with no search tool, recording recall, then the same twenty with retrieval enabled. The gap between the two numbers tells you which layer you are winning.
Where people get burned Pitfalls
The diagnostic is direct. No recall but strong retrieval means good tactical positioning and thin brand history. Substantial recall means the brand is in the model's settled knowledge, which is a durable advantage that competitors cannot buy quickly.
