Pathway has developed Baby Dragon Hatchling (BDH), described as a brain-inspired, post-transformer architecture. Unlike models that produce chain-of-thought tokens, BDH reasons in latent space. The AWS Machine Learning Blog outlines how Pathway builds and scales the architecture using Amazon SageMaker HyperPod. According to the post, a variant called BDH-CQ set a new cost-efficiency mark on the ARC-AGI-1 benchmark.

Why it matters

A post-transformer approach that reasons in latent space represents an alternative to prevailing transformer designs. The reported cost-efficiency result on the ARC-AGI-1 benchmark points to development aimed at balancing capability with resource use.

Who should care

Machine learning researchers and teams exploring alternatives to transformer architectures, as well as organizations evaluating training and scaling infrastructure such as Amazon SageMaker HyperPod, may find this development relevant.
