Who read this fact

Each model reads the same question separately: whether the quote from the source says what the fact states. A person reads when the models have no clear majority.

Read by GLM-4-9B Supports the fact

An open-weights model we deploy ourselves. It only accepts what the quote states plainly, nothing that has to be assumed.
