Brains with Gradients: Why Energy-Based Transformers Might Be the Future of Thinking Machines
TL;DR for operators Energy-Based Transformers are not another prompt trick, reasoning wrapper, or RL-flavoured attempt to make a chatbot show more homework. They change the model’s job. Instead of directly predicting the next token, frame, or image patch in one forward pass, an EBT learns a scalar energy function that scores whether a candidate prediction is compatible with its context. Lower energy means “this fits better.” Inference then becomes optimisation: start with a rough or random candidate, compute the gradient of the energy with respect to that candidate, and iteratively move toward a lower-energy prediction. ...
