Foundation models are redefining how AI systems are built.

  • Practitioners now follow a standard procedure to build their machine learning solutions: from a pre-trained foundation model, they fine-tune the weights on the target task of interest.

  • In our opinion, this is a missed opportunity, as these specialized models contain rich and diverse features.
