summary: "Cartesia has released an updated version of its Hierarchical Networks (H-Nets) architecture that allows large language models to learn from raw bytes, reportedly reducing training compute and data needs by 10x while matching the performance of a model trained on 11T tokens. The company also reported efficiency gains of 3-5x over existing methods in controlled scaling experiments."
