And so our leadership, our chief scientists, our heads of fine-tuning and RL, folks are actually really close to the training runs and actually look at things like how the training run is going, evals, looking at the underlying data. So actually staying really close and be excited to be in the details, I think have been a sign of really strong researchers and developing taste.
