Knowledge cutoff vs training data cutoff

Knowledge cutoff and training data cutoff are different dates: the knowledge cutoff is roughly how current a model's world knowledge is, while the training data cutoff is when its training data ends. Both shape what a model knows about you.

What we use this model for

We ask this model directly about your company to see how it describes you and which names it brings up in your space. It is one of several frontier models in our measurement set, so your visibility is read across the assistants people actually use rather than from a single model.
