Clarifai's Enlight custom model training lets you take advantage of our pre-trained models, which are trained on millions of inputs. This lets you train high-performing models that leverage the understanding from our pre-trained models using a very small number of inputs. On the other hand, with deep training, you can build an entirely custom neural network for your application from the ground up, and thus requires a higher number of inputs. Deep training is extremely powerful, particularly when you have unique data and need to maximize model accuracy. Learn more about deep training.
