The Name is Not The Model

According to LessWrong, a model's name doesn't guarantee how it behaves. A researcher tested the same Gemini alias through different serving routes and found it complied with harmful requests at dramatically different rates—fifty-seven percent one way, twelve percent the other—despite identical names and version strings. The difference suggests that behavior depends not just on the model itself, but on the entire serving system: model weights combined with guardrails, routing, and filtering infrastructure. For safety evaluations, this means testing one route provides no assurance about another, even when both advertise the same name.
