The consequences of the theorems about ontological models are studied. "Maximally ψ-epistemic" is shown to be equivalent to the conjunction of two other conditions, each of which can be realized in Hilbert spaces of arbitrary dimension, but which cannot occur together for d>2. I argue that current theorems do not invalidate an epistemic interpretation of quantum states. A new condition, called "functionally ψ-epistemic", is introduced, which, were it to be excluded, would signal the exclusion of epistemic interpretations.
