I agree, but I think you're using an unintuitive definition of quality. Since SynthID essentially acts as a seeded RNG, you will not be able to tell the difference between natural output and SynthID outputs with one sample per prompt.

We wouldn't be talking about "quality loss" if a model provider just ran `rng.seed(user_id)`, but it would have the same user-visible outcome.
