arXiv:2506.05233v2 Announce Type: replace Abstract: Sequence modeling is currently dominated by causal transformer architectures that use softmax self-attention. Although widely adopted, transformers require scaling memory and compute linearly during inference. A recent stream of work linearized the softmax operation, resulting in powerful recurrent neural network (RNN) models with constant memory and compute costs such as DeltaNet, Mamba or xLSTM. These models can be unified by noting that their recurrent layer dynamics can all be derived from an in-context regression objective, approximately
The continuous drive for more efficient and scalable AI models is leading researchers to re-evaluate and improve foundational architectures like RNNs, which offer advantages in memory and compute over traditional transformers.
This development represents a significant step towards more efficient and scalable AI, potentially enabling advanced models to run on resource-constrained devices or at a lower operational cost, broadening AI accessibility and deployment.
The dominant paradigm in sequence modeling, heavily reliant on transformer architectures, is being challenged by advancements in RNNs that offer constant memory and compute costs without sacrificing performance.
