Extropic
Extropic opens the first transformer family built for a probabilistic chip: 294 nanojoules per token against the H100's 40.9 microjoules
Z1T is Extropic's family of sparse transformer-like models designed for its probabilistic Z1 chip. The company reports over 100x energy efficiency against GPUs, opens the weights and the training recipe, and lists the limits of the measurement itself.
