Titans by Google: The Era of AI After Transformers?

Transformers, introduced in Google's 2017 paper "Attention is All You Need," revolutionized AI with their attention mechanism, enabling efficient processing of token sequences. However, their quadratic computational costs limit scalability for longer sequences. In contrast, recurrent models offer linear dependency but lack the performance of Transformers. Google Research's new architecture, Titans, mitigates Transformers' cost issues by implementing a deep neural long-term memory module inspired by human memory. This model updates weights based on surprising inputs, learns associations through a memory module, and shows promising results against various benchmarks, outperforming traditional models in long sequence tasks.

Transformers handle complete token sequences using an attention mechanism but face quadratic scaling costs.
