New kind of AI uses a fresh approach to reasoning —‬ researchers say it costs up to 11 times less to run than a leading OpenAI model

Pathway's new BDH-CQ model uses a "post-transformer" architecture that processes reasoning through numerical arrays and iterative loops instead of text tokens, keeping memory and computing costs stable. Despite modest benchmark scores, it runs up to 11 times cheaper than OpenAI's comparable model, potentially making advanced AI far more affordable to deploy.
